Abstract

The Camponotus subgenus Myrmosaga subgen. rev. from the Malagasy region is revised based on analysis of both qualitative morphological characters and morphometric traits. The multivariate analysis used the Nest Centroid (NC)-clustering method to generate species hypotheses based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were confirmed by cumulative Linear Discriminant Analysis (LDA). Morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. The present study places the subgenus Myrmopytia syn. nov. in synonymy to Myrmosaga. It recognizes 38 species, of which 19 are newly described: C. aina sp. nov., C. aro sp. nov., C. asara sp. nov., C. atimo sp. nov., C. bemaheva sp. nov., C. bozaka sp. nov., C. daraina sp. nov., C. harenarum sp. nov., C. joany sp. nov., C. karsti sp. nov., C. kelimaso sp. nov., C. lokobe sp. nov., C. mahafaly sp. nov., C. niavo sp. nov., C. rotrae sp. nov., C. sambiranoensis sp. nov., C. tapia sp. nov., C. tendryi sp. nov., C. vano sp. nov. Eleven species are redescribed: C. aurosus Roger, C. cervicalis Roger, C. dufouri Forel, C. gibber Forel, C. hagensii Forel, C. hova Forel, C. hovahovoides Forel, C. immaculatus Forel, C. quadrimaculatus Forel, C. roeseli Forel, C. strangulatus Santschi. The following are raised to species and redescribed: C. becki Santschi stat. nov., C. boivini Forel stat. rev., C. cemeryi Özdikmen stat. rev., C. mixtellus Forel stat. nov., C. radamae Forel stat. nov. Camponotus maculatus st. fairmairei Santschi syn. nov., is synonymized under C. boivini. The following are synonymized under C. cervicalis: Camponotus cervicalis gaullei Santschi, syn. nov.; Camponotus perroti Forel, syn. nov.; Camponotus perroti aeschylus Forel, syn. nov.; Camponotus gerberti Donisthorpe, syn. nov. Camponotus dufouri imerinensis Forel, syn. nov. is a synonym of C. dufouri, Camponotus hova var. obscuratus Emery, syn. nov. is a synonym of C. hova, Camponotus quadrimaculatus opacata Emery, syn. nov. is a synonym of C. immaculatus, Camponotus maculatus st. legionarium Santschi, syn. nov. is a synonym of C. roeseli, Camponotus hova maculatoides Emery, syn. nov. is a synonym of C. strangulatus.

Introduction

Given the striking morphological variation of Malagasy Camponotus, taxonomic knowledge of this genus has been advanced recently using a combination of traditional morphology-based study and a morphometry-based approach. These techniques and the use of other sources of evidence have helped assign individual specimens to a species, facilitate species recognition, and improve precision of species delimitation in recent revisions (Rakotonirina et al. 2016, 2017; Rasoamanana et al. 2017; Rakotonirina and Fisher 2018). We continue to apply these techniques to revise the subgenus Myrmosaga (Forel 1912) as part of an ongoing project to revise the entire genus in the Malagasy region.

Myrmosaga was created by Forel (1912) as a subgenus of Camponotus, but later it was synonymized under Mayria by Emery (1925) based on a few morphological characters that are shared by both subgenera. However, our observation of the samples collected from the recent extensive inventory of ant fauna in the Malagasy region revealed two separate groups. One group includes the species of Myrmosaga and another contains species that remain in the group Mayria. In addition, Camponotus imitator, the type species of the subgenus Myrmopytia (Emery, 1920a) is grouped with the species of Myrmosaga. This grouping is also supported by the molecular analysis using UCE (Ultra-Conserved Element) phylogenomic data (Unpublished data). Species of Myrmosaga are remarkably different from those of Mayria and therefore the subgenus needs to be revived now from synonymy. Myrmopytia is also synonymized under Myrmosaga in the present study. The other three species (C. jodina, C. karaha, and C. longicolis) recently described under Myrmopytia will be moved to a different subgenus (Rasoamanana in prep.).

Members of Myrmosaga are found only in Madagascar and surrounding islands of the southwest Indian Ocean region. They occupy all the terrestrial ecoregions encountered in this region. Morphologically, the worker castes of the subgenus present a wide range of features that are the result of its substantial adaptive radiation across these islands, but particularly in Madagascar. Several species within the subgenus show development of a few or many characters similar to fauna from the Afrotropical region. Our understanding of this observed morphological diversification has triggered taxonomic changes for some of the species that were described and combined previously under different subgenera of Camponotus (Table 1).

This proposed Myrmosaga classification is based on the use of additional morphological features thought to be relevant in defining the subgenus more precisely. Minor workers of Myrmosaga are generally characterized by the combination of the following morphological characters: clypeus medially carinate, mandible armed with six teeth, laterodorsal angle of mesosoma never marginate, petiolar node never conical.

The present revision recognizes 38 species in the subgenus Myrmosaga, provides an illustrated species-level identification key, and a description of each species complemented by high-resolution montage images and a geographic distribution map.

Materials

The present study includes all specimens of the subgenus Myrmosaga collected from the arthropod survey project conducted in Madagascar and surrounding islands in the Malagasy region by the members of the Madagascar Biodiversity Center and other ant researchers. Most of these collections were sampled from 1992 through 2018. All pinned specimens examined in this study are available on the AntWeb portal (http://www.antweb.org) and can be accessed using the unique identifying specimen code (CASENTnumber) assigned to each pinned specimen.

A total of 776 specimens from 324 collecting events was measured in this study (see Suppl. material 1). Collection event codes with prefix AND, ANTC, ARA, BLF, MG, or PSW indicate distinct collecting events, and were used as grouping factors in the NC-clustering method. One grouping factor may contain up to three individual specimens for measurements.

Methods

Using a Leica MZ12 binocular microscope, qualitative morphological examinations were conducted on minor and major workers to evaluate patterns of morphological discontinuities and phenotypic similarity. Observed discontinuities in morphological space could indicate reproductive boundaries between populations and as such were used to infer potential species limits. Species limits based on qualitative morphological characters were compared with the species hypothesis derived from the quantitative analysis of measurements. Differences between the sizes of the measured worker castes in the present study might result in a conflict between the two approaches. To avoid this conflict any specimen with unusual size class was removed from the analysis.

Digital color images of lateral and dorsal views of the entire body and full-face views of the head of each species were created using a JVC KY-75 or a Leica DFC450 digital camera with a Leica Z16 APO microscope and Leica Application Suite software (v3.8). These images are also available online on AntWeb (www.antweb.org) and are accessible using the unique identifying specimen code.

Distribution maps for all species were generated by importing specimen distribution records into the Diva GIS program (Hijmans et al. 2011). The major ecoregions of Madagascar were superimposed on the distribution of each species. Specimens with inadequate geographic coordinates were excluded from these maps. Information about the biology of each species was based on data obtained from specimen sampling (the nest series and isolated worker specimens) in the field.

Article 74 in the ICZN’s code states that a lectotype may be designated from syntype specimens which directly match the original description of a named species in order to stabilize the nomenclature. Therefore, the phrase “by present designation” is used to indicate a lectotype. As stated in Article 75.1 of the ICZN’s code, neotype designation is necessary for a name with no extant name-bearing type to objectively define the nominal taxon. Thus, a neotype has been selected according to the qualifying conditions specified in Article 75.3.

Etymologies are provided for new species to facilitate name stability. Etymologies indicate if the new name is a non-Latin or Latin (or Latinized) word. For Latin names, we also include the part of speech (nouns, adjectives, participles), gender (masculine, feminine, or neuter), number (singular or plural) and grammatical case (e.g. subjective/nominative, possessive/genitive).

Measurements

Morphometric measurements of the minor and major workers were taken using a Leica MZ12 stereomicroscope equipped with a cross-scaled ocular micrometer and an orthogonal pair of micrometers. All measurements and indices are presented as arithmetic means and ranges are shown as minimum and maximum values in parentheses. Body size dimensions are expressed in millimeters (mm) and all values were rounded to the second decimal place.

The following 19 morphometric measurements were evaluated in the present revision:

CL (Maximum cephalic length): The maximum midline length of the head in full-face view, measured from the midpoint of the posterior margin to the midpoint of the anterior margin of the clypeus.

ClyL (Clypeal length): the maximum midline length of the clypeus measured from the posterior margin to the anterior margin in anterodorsal view, in which the anterior and posterior clypeal margins are aligned to the same focus. Median concavity on either or both margins reduces the length of the clypeus.

CS (Cephalic size): The arithmetic mean of CL and CWb. CS is used to indicate the general body size of the ant.

CW (Maximum cephalic width): The maximum distance between the lateral margins of the compound eyes in full-face view.

CWb (Maximum head capsule width): The maximum width of the head excluding the compound eyes.

EL (Eye length): Maximum diameter of the compound eye.

FR (Frontal carina distance): The maximum distance between the frontal carinae.

GPD (Maximum tentorial pit distance): The longest distance between the centers of the fossae located at or very close to the posterolateral margin of the clypeus.

HTL (Maximum hind tibia length): Straight line length of the hind tibia measured from the constriction immediately before its proximal insertion to its distalmost point, excluding the bristles or spines. The measurement of the tibia is taken from any view where the constriction before its proximal insertion is visible.

ML (Mesosoma length): The longest median anatomical line that connects the posteriormost point of the propodeal lobe with the anteriormost point of the pronotal collar; preferentially measured in lateral view, but if one of the reference points is not visible, dorsal view may be used.

MPD (Mesothoracico-propodeal distance): With the promesonotal suture and the anterior petiolar foramen margin in the same plane of focus in dorsal view, the maximum midline length between the promesonotal suture and the posteriormost point of the propodeal process dorsal to the petiolar insertion (see Rakotonirina et al. 2016: fig. 1).

MPH (Mesothoracico-propodeal height): With the mesosoma in lateral view, the length of the line between the anteroventral corner of the mesopleuron dorsal to the insertion of the mesocoxa, and the dorsalmost point of the propodeum that is crossed by the measured line. The line is perpendicular to the diagonal line of the mesosoma that connects the anteriormost point of the pronotal shield and the posteriormost point of the propodeal process dorsal to the petiolar insertion, in lateral view.

MW (Mesosoma width): Maximum width of the pronotum in dorsal view, which in the subgenus Myrmosaga is also the maximum mesosomal width (hence “mesosoma width”).

NOH (Petiolar node height): The maximum distance between the petiolar spiracle and the dorsalmost point of the petiolar node.

OMD (Oculo-mandibular distance): The smallest distance between the anterior margin of the compound eye and the mandibular insertion to the head.

PEW (Petiolar width): The maximum width of the petiole in dorsal view.

PoOc (Postocular distance): The distance between the posteromedian margin of the head and the level of the posterior margin of the compound eyes measured along the midline of the head in full-face view.

PrOc (Preocular distance): The distance between the anteromedian margin of the clypeus and the level of the anterior margin of the compound eyes measured along the midline of the head in full-face view.

SL (Scape length): Straight line length of the first antennal segment excluding the basal condyle.

TCD (Torular carina distance): The minimum distance between the torular arches that surround the antennal insertion.

Multivariate statistical analyses

The datasets assessed in the present study consist of (1) the primary measurement data of the 19 morphological characters and the one calculated character CS (a widely applied size indicator) of each measured specimen (see table of basic measurements of the specimens in the Suppl. material 1), and (2) the ratios (indices) of measurements involving the comparison of one measured trait (variable) over another (CS, CL, or ML) to show the body proportions or shape of the specimen (Table 2). In Table 2, the ratios of measurements for minor and major workers of each species are presented as arithmetic means with standard deviation in the upper line and as ranges in square brackets in the lower line if more than two individual specimens are measured.

In some species, the existing samples were below the threshold level to apply the quantitative, morphometry-based classification methods and were not included in the analysis. However, the measurement values of the individual specimens were used in the description of each of these species whose delimitations are supported by the qualitative morphological traits and other data from their biology and ecology.

Morphometric data of the major workers are also provided in the description but were excluded in statistical analysis.

As different allometric properties are present in the Malagasy Camponotus (see Rakotonirina et al. 2016, 2017), we applied morphometric data obtained from minor workers for multivariate statistical analysis.

Species hypotheses were generated using the Nest Centroid clustering (NC-clustering) technique. The procedure followed Rakotonirina et al. (2016).

To validate the species boundaries and reliability of the clusters recognized by the exploratory analyses, cumulative Linear Discriminant Analysis (LDA) was performed repeatedly until the final classification, showing the highest posterior probability values, was attained.

Results and discussion

Multivariate statistical analysis of morphometric data

The NC-clustering dendrogram revealed 33 clusters, which are interpreted as 33 species (Fig. 1). The 33 species hypothesis proposed by the exploratory analysis was supported by the cumulative LDA, with 98.2% identification success (Table 3). Few species have conflicting identification features. These misidentifications could be attributed to similar morphology. Morphologically similar species frequently exhibit overlapping ranges of quantitative measurements and share qualitative morphological characters (Table 3).

Morphological diagnosis of the worker caste of Malagasy Myrmosaga

As for most Camponotus species, minor and major worker castes exist within a colony of the subgenus Myrmosaga. In addition, various worker forms showing continuous morphological variation between these two castes are observed. The following combination of characters can be used to reliably distinguish the two extreme worker castes in the subgenus Myrmosaga from other Malagasy subgenera and species groups of Camponotus.

Minor worker

Head elongate in full-face view, sides either converging or diverging posteriorly towards eye level to approximately parallel to each other and start rounding to posterior margin at ca. posterior 1/3 to posterior 1/5; posterior margin sometimes indistinct from lateral margins.
Mandible triangular, apical margin armed with six teeth. In some species, two apical teeth closer to each other than the other teeth.
Palp formula: 6,4.
Clypeus with median carina, its anteromedian margin mostly broadly convex, sometimes straight (C. dufouri, C. lubbocki, C. gibber, C. rotrae, C. immaculatus, etc.), projecting into triangular lobe (C. sambiranoensis, C. liandia); anterior margin rarely excised medially (C. lokobe).
Antenna with 12 antennomeres, elongate flagellomeres; antennal scape long, generally its distal 1/2 surpassing posterior cephalic margin, either covered or without erect hairs; apical antennomere slightly longer than other flagellomeres;

Major worker

Major worker similar to minor worker, but characterized by the following distinctive traits: larger, heart-shaped head; less protruding eye not breaking lateral cephalic margin; more robust mesosoma; stronger mandibles (armed with at least seven teeth and denticles); clypeus with anterolateral angle and straight anterior margin; antennal scape shorter, at most apical 1/3 extending beyond posterior margin of head; metanotum distinctly visible; petiolar node much higher than long (more flattened anteroposteriorly); more erect hairs on promesonotum and the junction of propodeal dorsum and declivity.

Comments

Originally Forel (1912) created Myrmosaga as a separate subgenus of Camponotus. Its synonymy under Mayria by Emery (1925) was based on similarity in the form of the clypeus, number of mandibular teeth, and shape of the mesosoma, and the petiole. It also was based on insufficient samples and comparative studies of different species belonging to these two subgenera. In the present study, we revealed many characters (in the Morphological diagnosis above) to distinguish Myrmosaga from Mayria. Members of Mayria are differentiated by the combination of the following characters: the clypeus lacks median carina, its anterolateral corner is rounded; the anterior margin of the pronotum is strongly convex in lateral view, forming a rounded flange and extended laterally to form an obtuse humeral angle; in dorsal view, the pronotal disc is rectangular with distinct lateral margins; the propodeum dorsum is never concave. Thus, Myrmosaga is revived from this synonymy here.

Species of the Malagasy Camponotus that have been previously placed in the subgenera Dinomyrmex and Myrmoturba by Forel (1914), in the subgenus Tanaemyrmex by Emery (1925), and two species (C. liandia and C. lubbocki) placed in the subgenus Mayria (Santschi 1914; Rakotonirina and Fisher 2018) are now moved into the subgenus Myrmosaga. This is because our detailed examination of the samples of Camponotus from the recent extensive survey of ants in Madagascar revealed that morphological differences between these taxa are due to their ability to adapt to diverse habitats. Similarities among them are the result of convergence by using similar techniques in exploiting similar habitats.

Camponotus imitator and the following three species C. jodina, C. karaha, and C. longicollis have morphologically similar minor worker caste and have been grouped together in the subgenus Myrmopytia (Rasoamanana et al. 2017). They are specifically characterized by the elongate mesonotum, which is constricted at midlength, and by the dorsally protruding rounded propodeum. However, C. imitator has a medially carinate clypeus with a broad rectangular projection, and a dorsally tapering petiolar node that are considered as some of the strong characteristics of the subgenus Myrmosaga. The other three species have triangular anterior clypeal margin and a lower anterior face and conical petiole. The specific shape of the mesosoma is just a result of the adaptive radiation among these three morphologically similar species across the terrestrial landscapes in Madagascar. Accordingly, C. imitator is presently moved to Myrmosaga and thus Myrmopytia is synonymized under the same subgenus. The three other species recently described under Myrmopytia are moved to a different subgenus (Rasoamanana in prep.).

Discussion

Camponotus aina looks similar to C. joany in that it has a straight propodeal dorsum, but in the latter species the propodeal dorsum is 2 × as long as the declivity and the dorsal margin of the petiolar node is shorter than the posterior margin.

Etymology

The species name aina is a non-Latin singular noun and is being used as a noun in apposition.

Figure 41.

Camponotus aro A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0489917 D distribution map.

Discussion

Camponotus aro is morphologically similar to C. gouldi in that both species are characterized by a broadly convex anteromedian margin of clypeus, but the latter species is diagnosed as having a head that extends posteriorly into a broad, short neck and its propodeal dorsum is straight.

The definition for C. aro is supported by the congruence between the results of traditional qualitative morphology and the NC-clustering technique. The classification of the samples for the species is at 100% success.

With characteristics of minor worker, except for the following characters: enlarged head (CS: 3.22±0.15; 3.03–3.39; CWb/CL: 0.93±0.01; 0.92–0.93) with noticeable medial excision on posterior margin; straight anterior clypeal margin; apical 1/4 of antennal scape surpassing posterior cephalic margin; propodeum dorsum and declivity the same length.

Distribution and biology

Camponotus asara is endemic to Madagascar and geographically restricted to the dry forest of the PN Zombitse in the southern high plateau of the island and the relict montane rainforest of the PN Ambohijanahary (Fig. 42D). Colony nests can be in rotten logs and in rot pockets above the ground. Workers have been found foraging in leaf litter and on the ground.

Figure 42.

Camponotus asara A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0493252 D distribution map.

Discussion

Camponotus asara is morphologically similar to C. bozaka and C. becki in that its petiolar node is more or less compressed anteroposteriorly in lateral view and its body color is black to dark brown, or the posterior portion of the mesosoma is pale brown to yellow. However, C. bozaka has a scalelike petiolar node, short and high mesosoma, and propodeal dorsum that joins the declivity in a blunt angle with a length < 2 × height of the declivity, the junction being angulate. Regarding C. becki, its anteromedian clypeal margin is truncate and a few erect hairs are present on the lateral margin of the head behind the level of the posterior ocular margin.

The cluster of the samples for C. asara in the NC-clustering dendrogram is supported by LDA with a classification success of 100%.

Etymology

The species name asara is a non-Latin singular noun used in apposition.

Description

Minor worker. With head in full-face view, lateral margins anterior to eye level parallel, converging abruptly towards posterior margin behind eye level; eye large and convex (EL/CS: 0.28±0.01; 0.26–0.30), interrupting lateral cephalic border, level of its posterior margin situated approximately at posterior 1/3 of head (PoOc/CL; 0.27±0.01; 0.25–0.29); frontal carinae close to each other, their distance equal to or smaller than their smallest distance to eye (FR/CS: 0.23±0.01; 0.22–0.25); clypeus with anterolateral angle and broadly convex anteromedian margin; mandible with two apical teeth distant from each other; antennal scape relatively long (SL/CS: 1.66±0.09; 1.48–1.84). Promesonotum weakly convex and mesopropodeum feebly convex (MPH/ML: 0.33±0.02; 0.29–0.36), mesonotum flat near weakly visible metanotal groove; propodeal dorsum anteriorly convex, posteriorly flat, rounding to declivity; propodeal dorsum 2 × as long as declivity. Petiole nodiform, its dorsal margin inclined posteriorly, rounding to anterior margin; anterior face 1/2 height of posterior face; femur of hind leg rounded axially, not twisted near base.

First and second gastral tergites without a pair of white spots; lateral margin of head without erect hairs; posterior cephalic margin with a pair of erect hairs; in profile, four pairs of erect hairs arranged from level of anterior margin of eye to posterior cephalic margin; erect hairs lacking from antennal scape, pubescence present; pronotum with a pair of erect hairs; posterodorsal angle of propodeum without erect hairs.

Major worker. With characteristics of minor worker, except for the typically broader head (CS: 3.23±0.34; 2.80–3.77; CWb/CL: 0.97±0.04; 0.89–1.03), with broadly concave posterior margin; apical 1/3 of antennal scape extending beyond posterior cephalic margin; robust mesosoma, with propodeal dorsum convex immediately posterior to metanotal groove and < 2 × as long as declivity; petiolar node compressed anteroposteriorly.

Distribution and biology

Camponotus atimo, endemic to Madagascar, generally occurs in the southern part of the island (Fig. 43D). Its habitats range from dry forest and coastal scrub on limestone of the southwestern region to the transitional forest in the extreme southeastern region and Uapaca woodland in the south-central region through the spiny forest and thicket in the extreme south of the island. Field work during the past 25 years has found this species foraging mostly on the ground and through leaf litter, and very rarely on lower vegetation. It usually nests under stones, in rotten logs and soil layers, and rarely in tree stumps.

Figure 43.

Camponotus atimo A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0454042 D distribution map.

Discussion

Camponotus atimo may be difficult to distinguish from C. tapia in that both species have the same body shape and the dorsum of the head is fringed with four or more pairs of erect hairs arranged successively from the level of the anterior ocular margin towards the posterior cephalic margin. However, in C. tapia, the junction of the propodeal dorsum to declivity surface is angulate.

Camponotus atimo also may be confounded with C. strangulatus, but the latter is characterized by the head having only three pairs of erect hairs arranged successively from the level of anterior ocular margin towards the posterior cephalic margin.

The identity of C. atimo, based on traditional qualitative taxonomy, has been confirmed by multivariate morphometrics. The grouping of the samples of C. atimo generated by the NC-clustering method is corroborated by cumulative LDA with a classification success of 100%.

Etymology

This new name atimo is a singular non-Latin noun used in apposition, derived from the Malagasy word for “south” in reference to the restricted distribution of the species to the southern half of Madagascar.

Major worker. Differing from minor worker in the following characters: larger head (CS: 2.24±0.11; 2.15–2.37; CWb/CL: 0.92±0.03; 0.87–0.95), with broadly slight medial concavity on posterior margin; apical 1/3 of antennal scape surpassing posterior cephalic margin; with mesosoma in lateral view, length of propodeal dorsum the same as height of propodeal declivity; petiolar node more compressed anteroposteriorly.

Distribution and biology

The distribution of C. aurosus is restricted to Mauritius and Reunion islands (Fig. 44D). In these islands, this species occupies primary and disturbed rainforest habitats, where workers have been found foraging on the ground and on lower vegetation and nest sites have been located in rotten logs, in the ground, under stones, and in tree trunks.

Figure 44.

Camponotus aurosus A lateral view B head in full-face view C dorsal view of minor worker CASENT0064815 D distribution map.

Discussion

Camponotus aurosus is similar to C. hagensii with respect to the shape of the head and the presence of erect hairs on the lateral cephalic margin, but the latter is characterized by the straight anteromedian margin of its clypeus, low and long mesosoma, and the presence of some pubescence on the gastral tergites.

The grouping of the C. aurosus samples in the same cluster shown by the dendrogram of multivariate morphometric analysis is corroborated by the cumulative LDA at 100% identification success. This result is congruent with that of the qualitative morphology-based study.

Major worker. Unknown

Distribution and biology

Camponotus bemaheva is restricted to the spiny bush and thicket of the southern region and the dry forest habitats of western Madagascar (Fig. 46D). The few colony nests that have been found were collected from rotten logs and under stones, but workers have been collected while foraging on the ground or on low vegetation.

Figure 46.

Camponotus bemaheva A lateral view B head in full-face view C dorsal view of minor worker CASENT0154158 D distribution map.

Discussion

Workers of C. bemaheva look very similar to those of C. daraina in that they have closely spaced apical teeth on the mandibles and the lateral margins of their head converge posteriorly towards eye level, but the latter is characterized by the presence of erect hairs on the lateral cephalic margin posterior to eye level.

The alignment of C. bemaheva in the same cluster displayed by the dendrogram of multivariate morphometric method is confirmed by the cumulative LDA at 100% identification success, validating the taxonomy hypothesized by qualitative morphology.

Etymology

The new species bemaheva is a non-Latin proper noun used in apposition and is named in honor of Fidelis Bemaheva for his help collecting ants in the Malagasy region.

Diagnosis

Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible normally spaced; antennal scape covered with suberect hairs inclined at ca. 45°; in lateral view, posterior 1/2 of mesonotum to posterodorsal corner of propodeum somewhat convex, propodeal dorsum ca. 2 × as long as the height of declivity surface.

Description

Minor worker. In full-face view, lateral cephalic borders anterior to level of eye parallel to each other, converging progressively towards posterior margin behind eye level; eye protruding and large (EL/CS: 0.32±0.02; 0.29–0.36), breaking lateral cephalic margins; head sides behind eye level 1/4 length of head (PoOc/CL: 0.27±0.01; 0.24–0.30); frontal carinae widely diverging posteriorly (FR/CS: 0.32±0.01; 0.30–0.35); clypeus with anterolateral angle, its anteromedian margin with blunt angle or convex; mandible with two apical teeth distant from each other; antennal scape relatively long (SL/CS: 1.37±0.10; 1.22–1.56). Promesonotum weakly convex and mesopropodeum feebly convex, mesonotum with posterior portion flat immediately anterior to metanotal groove, metanotum weakly visible, propodeal dorsum anteriorly convex and posteriorly flat, dorsal margin of propodeum and declivity joining at a blunt angle, height of propodeal declivity 1/2 length of propodeal dorsum. Petiolar node flattened, short, and high, without noticeable dorsal margin; tibia of hind leg rounded axially, without twist in the basal portion.

First and second gastral tergites without a pair of white spots; lateral margin of head anterior to eyes level with erect hairs, which are absent behind eyes; posterior margin of head with a pair of erect hairs; antennal scape covered with erect hairs inclined at 45°; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Differing from minor worker in having larger head (CS: 2.29±0.28; 1.96–3.12; CWb/CL: 0.91±0.04; 0.86–0.99), short antennal scape barely surpassing posterior cephalic margin; robust mesosoma with distinct metanotum, and petiolar node as high as long. Other characters as in minor worker.

Distribution and biology

The distribution of C. boivini is generally limited to western and the high plateau of Madagascar (Fig. 47D). This species occurs mostly in dry forest habitats in the north through spiny forest areas in the south. Along its north-south range it can be found in gallery forests, disjunct montane rainforest, Uapaca woodlands, and savannah grasslands. When nesting in rotten logs, rotting tree stumps, under stones, in dead branches, twigs on the ground, and in the soil, C. boivini typically forages in leaf litter and seldom on the forest floor and low vegetation.

Figure 47.

Discussion

Camponotus boivini may be confused with C. cemeryi but the latter is characterized by a short and high mesosoma which shows a strongly convex dorsal outline. Camponotus boivini can be confounded with C. mixtellus but workers of the latter species have an antennal scape covered with suberect hairs inclined at ca. 30°, are generally larger (CS: 1.56±0.13; 1.16–1.83; ML: 2.76±0.16; 3.10–3.45), and are mostly found in the rainforest of the region.

Santschi (1911a) originally described Camponotus maculatus st. fairmairei without any comparison of the specimens to those of other species, though his description corresponds to the type specimens of C. boivini. The observation of the samples and the distributional data obtained from the recent ant survey in Madagascar combined with this information are sufficiently enough to reasonably synonymize Camponotus maculatus st. fairmairei here.

The definition of C. boivinii based on traditional qualitative morphology is congruent with the results achieved by the exploratory analysis and the cumulative LDA, which has an identification success of 100%.

Diagnosis

With head in full-face view, lateral margin of head anterior to eye level parallel, lacking erect hairs; clypeus with noticeable anterolateral corner; in profile, petiolar node anteroposteriorly compressed.

Description

Minor worker. In full-face view, lateral cephalic margins anterior to level of eye approximately parallel, evenly rounding to posterior margin; eye protruding and large (EL/CS: 0.28±0.01; 0.26–0.30), breaking lateral cephalic margin, level of its posterior margin located at ca. posterior 1/4 of head (PoOc/CL: 0.25±0.01; 0.23–0.26); frontal carinae close to each other, their distance equal to or smaller than smallest distance of one to the eye (FR/CS: 0.28±0.01; 0.28–0.29); clypeus with anterolateral corners, its anteromedian margin broadly triangular or convex; mandible with two apical teeth normally spaced; antennal scape relatively short (SL/CS: 1.19±0.05; 1.08–1.25). Promesonotum weakly convex, mesopropodeum almost flat; mesonotum flat immediately anterior to metanotal groove; metanotal groove weakly visible; dorsal margin of propodeum straight and joining declivity at a noticeable angle, propodeal dorsum < 2 × as long as declivity. Petiolar node scalelike with sharp dorsal margin; femur of hind leg rounded axially and not twisted basally.

First and second gastral tergites without a pair of white spots; erect hairs on lateral margin of head not present; posterior margin of head with two erect hairs; with head in profile, four pairs of erect hairs arranged from level of anterior margin of eye to posterior cephalic margin; antennal scape covered only with appressed hairs; pronotum, mesonotum, and posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 2.07±0.18; 1.91–2.40; CWb/CL: 0.95±0.03; 0.90–0.98) with slightly concave to almost straight posterior margin; apical 1/3 of antennal scape extending beyond posterior cephalic margin; robust mesosoma with length of propodeal dorsum approximately the same as height of declivity.

Distribution and biology

Known only from the south-central high plateau of Madagascar, C. bozaka occupies rubicole thicket, Uapaca woodland, savannah grassland, and shrubland habitats (Fig. 48D). Worker specimens have been found foraging through leaf litter and on low vegetation. The nest sites are in the ground or under stones.

Figure 48.

Camponotus bozaka A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0217309 D distribution map.

Discussion

See discussion under C. asara. The taxonomic identity of C. bozaka based on conventional qualitative morphology is supported by multivariate morphometric analysis. The grouping shown by the morphometric dendrogram and confirmed by cumulative LDA at 100% success supports the existence of the species.

Etymology

This new name bozaka is a singular non-Latin noun used in apposition and is derived from the Malagasy word for “dried grass” in reference to the abundant grassland where this species occurs.

Major worker. Characteristics the same as minor worker, except the enlarged head (CS: 2.41±0.22; 2.19–2.72; CWb/CL: 0.87±0.05; 0.83–0.94); stronger mandible; apical 1/5 of antennal scape surpassing posterior cephalic margin; metanotum visible; propodeal dorsum slightly convex joining a vertically built declivity at rounded angle; petiolar node much higher than long.

Distribution and biology

Camponotus cemeryi occurs in dry forest and spiny forest of west Madagascar and in the savannah shrubland and woodland of the central plateau (Fig. 49D). Along its distribution, members of the species can also be found in gallery forest habitats and in transitional forest between dry and humid forests. It may also establish colonies in human-modified habitats on the high plateau. Specimens have been collected mostly foraging on the forest floor and rarely on lower vegetation. The species nests in rotten logs, in the ground, under stones, and in rotting tree stumps.

Discussion

Members of C. cemeryi can be separated from similar species like C. boivini by the strongly convex dorsal outline of its short and high mesosoma. It can be differentiated from C. mahafaly by the presence of erect to suberect hairs on the antennal scape.

Worker specimens that show the typical form of C. cemeryi are generally found across the western dry forest of Madagascar, but specimens have been collected from the mountaintops on the high plateau of the island that present morphological variation in which the lateral margin of head posterior to eye level is covered with erect hairs, three pairs of erect hairs are present on posterior cephalic margin, and body color is generally depigmented yellow or brown with depigmented yellow in some parts of the body. Based on these characters, this variant may constitute a separate species; however, the dendrogram based on quantitative morphological analysis did not support this hypothesis. The variant is nested within the cluster of the typical form of the species according to the NC-clustering method, and all of these samples were correctly classified by LDA at 100% success.

Description

Minor worker. In full-face view, head sides converging progressively towards short posterior margin; eye protruding and large (EL/CS: 0.28±0.01; 0.26–0.30), breaking lateral cephalic margin, level of posterior margin located at posterior 1/3 of head (PoOc/CL: 0.30±0.01; 0.29–0.31); frontal carinae wide (FR/CS: 0.27±0.01; 0.26–0.28), distance between them larger than smallest distance to eye; clypeus with anterolateral angle and anteromedian margin with blunt angle or convex; mandible with two apical teeth distantly spaced; antennal scape relatively long (SL/CS: 1.81±0.12; 1.57–1.94). Promesonotum weakly convex, mesopropodeum almost flat, joining declivity with rounded angle; metanotal groove weakly visible; propodeal declivity 1/2 length of the dorsum. Petiolar node as long as high, with dorsal margin inclined posteriorly and rounding to anterior margin; anterior face 1/2 height of the posterior; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral margin of head with erect hairs; more than six erect hairs present near posterior margin of head; antennal scape covered with erect to suberect hairs inclined at ca. 45° as well as appressed hairs; pronotum covered with few erect hairs, mesonotum with a pair of hairs; posterodorsal angle of propodeum with two pairs of erect hairs.

Major worker. Characteristics the same as minor worker, except the enlarged head (CS: 4.17±0.35; 3.83–4.63; CWb/CL: 0.91±0.03; 0.85–0.93); the more strongly built mandible; apical 1/4 of antennal scape surpassing posterior cephalic margin; pronotum convex, mesonotum sloping towards metanotum, propodeal dorsum feebly convex and its junction to declivity broadly angulate; petiolar node much higher than long.

Distribution and biology

Camponotus cervicalis is only known to occur in littoral forests and lower elevations of the rainforests in the east of Madagascar between the Ambanitaza forest in the north and the RNI Betampona in the south (Fig. 50D). Workers of the species have been found foraging on the ground and through leaf litter, but nest sites range from rotten logs, rotting tree stumps, rot pockets above the ground, live trees, under tree bark, and in moss and leaf litter.

Figure 50.

Camponotus cervicalis A lateral view B head in full-face view C dorsal view of minor worker CASENT0217303 D distribution map.

Discussion

Camponotus cervicalis and C. niavo look similar, but in the latter, the level of the posterior ocular margin is located at posterior 1/4 of length of head and its antennal scape lacks appressed hairs.

In his original description of Camponotus gaullei, Santschi (1911a) discussed the resemblance of the species to C. cervicalis and C. dufouri and no strong separating characters were provided. However, with recent extensive sampling of the Malagasy ant fauna, the observation of the range of worker class sizes in these latter species indicates the closer similarity between C. cervicalis and C. gaullei. Combined with the close distance between the type localities of both species, this information would be enough to synonymize C. gaullei under C. cervicalis.

The description of C. perroti by Forel (1897) was based on a limited number of worker specimens which had a close similarity to C. cervicalis and C. dufouri. Careful examinations of more specimens obtained from the recent ant surveys in Madagascar show that C. perroti and C. cervicalis belong to the same species and that C. perroti merits its placement as a junior synonym of C. cervicalis.

Forel’s description of C. perroti aeschylus was based only on a single alate queen, and the comparison of this specimen with the queen specimens of C. cervicalis collected from its geographical range across Madagascar revealed that this type specimen was a queen of C. cervicalis.

Donisthorpe’s description of Camponotus gerberti did not compare the characters of the taxa to those of other species, although this description morphologically matches the type specimens of C. cervicalis. The data obtained from the recent ant survey in Madagascar and this information are sufficient to reasonably synonymize C. gerberti under C. cervicalis.

The identity of C. cervicalis based on conventional qualitative taxonomy is recognized by multivariate morphometric analysis. The cluster of the samples of the species created by NC-clustering method is confirmed by cumulative LDA with an identification success of 100%.

With head in full-face view, lateral borders gradually converge to anterior eye level, strongly converging behind eye level; eyes protruding and large (EL/CS: 0.28±0.01; 0.26–0.30), interrupting lateral cephalic border, level of its anterior margin located at posterior 1/3 of head (PoOc/CL: 0.29±0.01; 0.28–0.30); frontal carinae not widely opened posteriorly (FR/CS: 0.25±0.001; 0.24, 0.26), distance between them larger than smallest distance to eye; clypeus without well-defined anterolateral angle and with anteromedian margin broadly convex; mandible with two apical teeth closely placed; antennal scape relatively long (SL/CS: 1.72±0.06; 1.56–1.82). Promesonotum weakly convex, mesonotum posterior portion flat immediately anterior to weakly visible metanotal groove; propodeal dorsum almost straight, rounding to short declivity 1/2 length of propodeal dorsum. Petiolar node is short and high, with dorsal margin inclining posteriorly and forming a blunt angle with anterior face that has a height ca. 1/2 that of posterior face; femur of hind leg axially rounded, not twisted near base.

First and second gastral tergites without a pair of white spots; head covered with erect hairs on lateral margin, six erect hairs near its posterior margin; antennal scape covered with suberect hairs inclined ca. 30°; pronotum and anterior part of mesonotum covered with erect hairs; posterodorsal angle of propodeum with two pairs of erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 13.54±0.25; 3.12–3.76; CWb/CL: 0.90±0.04; 0.85–0.94) with markedly concave posterior margin; apical 1/4 of antennal scape surpassing posterior margin of head; two apical teeth of mandible distantly spaced; robust mesosoma, with promesonotum forming even convexity, metanotum distinctly visible, propodeal dorsum slightly convex immediately behind metanotum, joining declivity surface at a blunt angle, < 2 × as long as declivity; petiolar node much higher and more compressed anteroposteriorly.

Distribution and biology

The distribution of C. daraina is generally limited to the northern and western slopes of Madagascar. The species occurs in dry forest habitats, transitional forests, and rainforests of the Daraina region, transitional forests of Montagne d’Ambre and the Ampasindava Peninsula, and rainforests of RS Manongarivo (Fig. 51D). Camponotus daraina is strictly terrestrial; its workers forage mainly on the forest floor and through leaf litter, while its nests have been found in rotten logs and under stones.

Figure 51.

Camponotus daraina A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0077433 D distribution map.

Discussion

Camponotus daraina looks similar to C. bemaheva and C. roeseli but C. bemaheva lacks erect hairs from the lateral margin of the head posterior to the eye level and in C. roeseli the integument is either entirely reddish black or the head and the gaster are reddish black and the mesosoma is yellowish orange to reddish orange.

The identification of C. daraina based on conventional morphology-based taxonomy has been confirmed by multivariate morphometrics. The grouping of the samples of C. daraina produced by the NC-clustering method is corroborated by LDA with a classification success of 100%.

Etymology

The species name daraina is a singular non-Latin noun used in apposition and refers to the type locality.

Diagnosis

With head in full-face view, lateral cephalic margins converge posteriorly towards eye level, strongly converging from posterior ocular margin to occipital corner of head; anteromedian margin of clypeus straight; two apical teeth of mandible normally spaced; lateral cephalic margin anterior to eye level covered with erect hairs.

Description

Minor worker. In full-face view, lateral cephalic margins converging progressively towards posterior margin or slightly converging to level of anterior ocular margin and strongly converging posteriorly; eye large and convex (EL/CS: 0.28±0.02; 0.25–0.31), breaking lateral cephalic border, located at midlength of head, level of its posterior margin within the posterior 1/3 of head (PoOc/CL; 0.33±0.01; 0.31–0.36); frontal carinae more or less wide, posteriorly parallel (FR/CS: 0.25±0.01; 0.24–0.27), their distance larger than smallest distance to eye; clypeus with anterolateral angle and medially slightly concave anteromedian margin; two apical teeth of mandible distantly spaced; antennal scape relatively long (SL/CS: 1.93±0.08; 1.76–2.12). Mesosoma long and low (MPH/ML: 0.29±0.01; 0.27–0.32), with slightly convex promesonotum, nearly flat mesopropodeum, and feebly visible metanotal groove; junction of propodeal dorsum to declivity bluntly angulate; propodeal declivity 1/3 length of dorsum. Petiole nodiform, tapering dorsally; its dorsal margin inclined posteriorly and forming a blunt angle to anterior face; posterior face 3 × as high as the anterior; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral margin of head covered with erect hairs; near posterior margin of head with more than six erect hairs; antennal scape covered with erect hairs inclined at ca. 45°; pronotum with numerous erect to suberect hairs; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. With characteristics of minor worker except for the following divergent characters: larger head (CS: 3.93±0.51; 3.46–4.54; CWb/CL: 0.88±0.08; 0.80–0.97), with concavity on posterior margin; anteromedian margin of clypeus slightly concave; apical 1/3 of antennal scape surpassing posterior cephalic margin; promesonotum and propodeum in separate convexity; mesonotum and propodeal dorsum 2 × as long as declivity, with blunt angle junction.

Distribution and biology

Camponotus dufouri is only known from Madagascar. Its distribution follows that of eastern humid forests ranging from the littoral to the montane rainforest of the island (Fig. 52G). Its colony nests have been found mostly in rotten logs, rotten sticks, and rotting tree stumps, and rarely in dead branches, twigs, and bamboo on the ground. Workers forage frequently on the ground and in leaf litter, rarely on low vegetation.

Figure 52.

Discussion

A clypeus with a straight anteromedian margin makes C. dufouri easy to separate from C. lokobe. Also, in C. tendryi, when the head is set in full-face view, the lateral cephalic margin posterior to the eye level is without erect hairs and its body size is smaller (CS: 1.57±0.01; 1.56–1.58), while in C. dufouri, erect hairs are present on the lateral cephalic margin posterior to the eye level and its body size is larger (CS: 1.97±0.19; 1.66–2.26).

A verification of the syntype workers of C. dufouri imerinensis demonstrates that they were indistinguishable from the syntypes of C. dufouri. Moreover, since the geographic distribution of C. dufouri is ranging from the littoral to the montane rainforests of Madagascar where the type specimens of the subspecies name were collected, it is consequently correct to synonymize it under C. dufouri.

The qualitative morphology-based study of C. dufouri agrees with the multivariate statistical analysis and both methods support the taxonomic delimitation for this species. The validity of the species, supported by the grouping obtained from NC-clustering, is confirmed by LDA with an identification success of 100%.

In full-face view, head sides diverging towards broadly convex posterior margin; eye slightly protruding and small (EL/CS: 0.27±0.01; 0.24–0.30), not breaking lateral cephalic margin, level of its posterior margin located at ca. posterior 1/4 of head (PoOc/CL: 0.25±0.01; 0.23–0.28); frontal carinae wide and diverging posteriorly (FR/CS: 0.35±0.01; 0.33–0.36), distance between them larger than their smallest distance to eye; clypeus with anterolateral angle and straight anteromedian margin; mandible with two apical teeth distant from each other; antennal scape relatively long (SL/CS: 1.17±0.07; 0.93–1.27). Pronotum and mesonotum forming a separate convexity; propodeal dorsum convex anteriorly, concave medially, then flat posteriorly, joining declivity in noticeable angle; metanotal groove weakly visible; propodeal declivity 3/4 length of dorsum. Petiolar node short and high, with dorsal margin straight then rounding to both anterior and posterior faces; anterior face almost 2/3 height of posterior face; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites with a pair of white spots; lateral margin of head without erect hairs; three pairs of erect hairs present near posterior margin of head; antennal scape only covered with appressed hairs; pronotum with few erect hairs; mesonotum with a pair of erect hairs; posterodorsal corner of propodeum with two pairs of erect hairs. Body color shining brown to dark brown; apical section of appendages lighter in color.

Major worker. With characteristics of minor worker except: enlarged head (CS: 2.45±0.21; 2.21–2.82; CWb/CL: 1.05±0.04; 1.01–1.10) with broadly concave posterior margin; anteromedian clypeal margin noticeably excised medially; antennal scape hardly extending beyond posterior cephalic margin; robust mesosoma, pronotum, and mesonotum an even convexity, metanotum distinct, propodeal dorsum sloping straight to declivity, approximately the same length as declivity; petiolar node more flattened anteroposteriorly.

Distribution and biology

Camponotus gibber occurs in mid-altitude rainforest, montane rainforest, open areas on the forest edge, and the savannah grassland of the high plateau of Madagascar. Its distribution ranges from the RS Manongarivo and PN Marojejy in the north through the Corridor Forestier Analamay-Mantadia and PN Andringitra in the south-central region to the PN Andohahela and Anosyenne Mountains in the south. It has also colonized the littoral rainforest of Ambondrobe Vohemar, the dry forest of the PN Isalo, and cultivated land in the Andrambovato Forest (Fig. 53D). Individual workers forage mostly on the ground and through leaf litter, and rarely on lower vegetation. Nests are typically in rotten logs and rotting tree stumps, but seldom in the ground, in root mats on the ground, in dead twigs above the ground, in moss and leaf litter on live trees, and under tree bark.

Discussion

Camponotus gibber may be difficult to differentiate from C. rotrae and C. quadrimaculatus in that they have two pairs of white spots on the second and third abdominal tergites. In both latter species, however, the pronotum, mesonotum, and propodeum do not form separate convexities, the metanotal groove is not depressed, and the dorsal face of its petiolar node joins the posterior face at an angle.

There are apparently three forms within C. gibber. These are geographically isolated across their distribution along the eastern rainforest of Madagascar due to the presence of high mountain chains in northwestern Madagascar. In the first form, the mesosoma strongly forms separate convexities and the propodeal dorsum is more or less straight. The second form is characterized by a more or less continuous dorsal outline of the mesosoma and a broadly concave propodeal dorsum. The third form constitutes intermediate degrees of these phenotypic variations because workers present separate convexities of mesosoma and a slightly concave propodeal dorsum. The members of the first two forms show morphological variabilities that gradually merge in the third form.

The relatively low 91.89% classification success attained by LDA is due to the misclassification of three minor workers as C. quadrimaculatus. This is because the third variant in C. gibber and members of C. quadrimaculatus species share qualitative morphological traits, and both species display overlapping ranges of quantitative measurements. The grouping of C. gibber in the same cluster shown by the dendrogram of multivariate morphometric analysis corroborates the species hypothesized by the taxonomic revision based on qualitative morphology.

Diagnosis

With head in full-face view, lateral margins of head anterior to eye level parallel and lacking erect hairs, posterior portion of head extending into a neck and anteromedian clypeal margin continuously forming broad convexity; dorsal outline of mesosoma broadly convex; body color black to dark brown.

Description

Minor worker. In full-face view, head sides anterior to level of eye approximately parallel; lateral cephalic margins posterior to level of eye converging posteriorly and projecting into short neck; eye medium (EL/CS: 0.24±0.01; 0.23–0.26), protruding, and breaking lateral cephalic border, level of posterior margin located approximately at posterior 1/3 of head (PoOc/CL: 0.29±0.02; 0.26–0.32); frontal carinae more or less wide posteriorly (FR/CS: 0.26±0.01; 0.25–0.27), the same width as its smallest distance to eye; clypeus without anterolateral angle, anteromedian margin broadly rounded, mandible with two apical teeth distantly spaced; antennal scape relatively long (SL/CS: 1.56±0.06; 1.44–1.66). Mesosoma presenting even convexity; promesonotum strongly convex, posterior portion of mesonotum flat immediately anterior to weakly visible metanotal groove; propodeal dorsum almost flat, its junction to declivity bluntly angulate; propodeal dorsum 3 × as long as declivity. Petiole nodiform, with dorsal margin inclined posteriorly, forming a blunt angle to anterior margin, medially excised at the junction to posterior margin, anterior face 1/2 height of posterior face, which is inclined anteriorly to the dorsum; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral margin of head without erect hairs; erect hairs lacking near the end of neck; antennal scape without suberect hairs and covered with short appressed hairs; pronotum with a pair of erect hairs; posterodorsal angle of propodeum without erect hairs.

Major worker. Characteristics the same as minor worker, except the enlarged head (CS: 5.19±0.23; 4.89–5.51; CWb/CL: 0.98±0.01; 0.97–1.00), which has no prolonged neck; the more strongly built mandible; antennal scape not extending beyond posterior cephalic margin; promesonotum convex; metanotal groove visible; propodeal dorsum feebly sloping towards declivity, its length the same as the height of declivity; petiolar node compressed anteroposteriorly.

Distribution and biology

The dry forest of the west, the spiny forest and thicket of the southwest, the transitional humid forest in the PN Andohahela, the savannah shrubland and woodland, and the Uapaca woodland and montane rainforest of the south-central high plateau of Madagascar are all habitats where C. gouldi occurs (Fig. 55D). This species nests mostly in rotten logs, in the ground, and under stones, rarely in rotting tree stumps and rotten sticks. Workers forage most often on the ground and seldom on lower vegetation.

Discussion

Camponotus gouldi is mostly similar to C. aro, but the posterior portion of the head for the latter is normally rounded, not extending into a short neck, and the propodeal dorsum immediately posterior to the metanotal groove is convex, then becomes concave medially and rounds to the declivity surface.

For C. gouldi, the decisions drawn from qualitative morphology-based taxonomy agree with the classification hypothesis provided by the exploratory data analysis and the cumulative LDA of the multivariate morphometrics. The combination of this information corroborates the status of C. gouldi as a species.

Neotype designation has been made for C. gouldi because its type is presumed lost. No type specimen could be found at the renowned museums in Europe that might have held the specimen. One of the author BLF visited the Forel collection at MHNG, MNHN, NHMB, and MSNG and could not find the type for C. gouldi. Also, the type specimen appears to be absent from the little-known collection of Forel types at Naturmuseum Solothurn (Germann 2017). Morphological characters that define the designated neotype are in accordance with the original description of the former holotype specimen. Since the original type locality was not precisely located within Madagascar, the new locality type has been chosen on the basis of where the species was most often collected across its geographical distribution.

In full-face view, lateral margin of head anterior to eye level diverging posteriorly and covered with erect hairs; anterior clypeal margin truncate; mesosoma in profile low and long; gastral tergites without abundant pubescence; head and gaster black, mesosoma reddish orange to brown.

Description

Minor worker. In full-face view, head sides diverging towards broadly convex posterior margin or parallel anterior to eye level and rounding evenly to posterior border; eye protruding and large (EL/CS: 0.30±0.01; 0.28–0.33), breaking lateral cephalic margin; level of its posterior margin located ca. at posterior 1/4 of head (PoOc/CL: 0.25±0.01; 0.23–0.25); frontal carinae wide (FR/CS: 0.34±0.01; 0.31–0.35), posteriorly diverging, distance between them larger than their smallest distance to eye; clypeus without well-defined anterolateral corner, anteromedian margin approximately truncate; mandible with two apical teeth distantly spaced; antennal scape relatively long (SL/CS: 1.24±0.06; 1.09–1.36). Promesonotum weakly convex, mesonotum with posterior portion flat immediately anterior to weakly visible metanotal groove; propodeal dorsum almost straight, its junction to declivity bluntly angulate; height of propodeal declivity 3/4 length of dorsum. Petiolar node short and high; its dorsal margin inclined posteriorly, rounding to anterior margin; height of anterior face 2/3 that of posterior; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; erect hairs on lateral margin of head lacking; more than six erect hairs present near posterior margin of head; antennal scape covered only with suberect hairs inclined at ca. 30° and appressed hairs; pronotum with few erect hairs, mesonotum bearing a pair of erect hairs; posterodorsal corner of propodeum with two pairs of erect hairs. Head, antenna, and gaster dark brown or reddish brown; mesosoma, petiolar node, and legs yellow to orange-yellow.

Major worker. Differing from minor worker in having larger, heart-shaped head (CS: 2.37±0.26; 2.00–2.70; CWb/CL: 0.97±0.05; 0.92–1.04) with broadly concave posterior margin, anteromedian margin of clypeus slightly excised medially; apical 1/4 of antennal scape extending beyond posterior cephalic margin; robust mesosoma with distinct metanotum; propodeal dorsum convex immediately behind metanotum, < 2 × the height of declivity surface; petiolar node much higher than long and tapering dorsally.

Distribution and biology

Camponotus hagensii is known mostly from montane rainforest, montane ericoid thicket, philipia forest, montane shrubland, and savannah grassland of the high plateau ranging from the PN Marojejy in the north to the Anosyenne Mountains in the south (Fig. 56D). The species has been found nesting in the ground, in root mat layers on the ground, and in rotting tree stumps. Workers have been found foraging frequently on the ground and leaf litter, rarely on low vegetation.

Figure 56.

Camponotus hagensii A lateral view B head in full-face view C dorsal view of minor worker CASENT0191568 D distribution map.

Discussion

Camponotus hagensii is similar to C. aurosus with respect to the bicolored body and the presence of erect hairs on the lateral margin of the head anterior to eye level, but in C. aurosus the anterior clypeal margin is broadly triangular, the mesosoma is short and high in profile, and the gastral tergites are covered with abundant pubescence.

The cluster of C. hagensii samples presented by the dendrogram of multivariate morphometric analysis is supported by the cumulative LDA at 100% identification success. This finding is consistent with the results of the qualitative morphology-based study.

Body color orange-brown with darker coxa, junction of segments, abdominal sternites, and appendices.

Major worker

Unknown.

Distribution and biology

Endemic to Madagascar, C. harenarum is only known from the littoral rainforest of Analabe in Daraina, in the northeastern region of the island (Fig. 57D). This species has been found nesting in rotten logs and foraging on the forest floor and on lower vegetation.

Figure 57.

Camponotus harenarum A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0499207 D distribution map.

Discussion

Camponotus harenarum can be confounded with C. karsti, but the latter has a more sloping anterior portion of the propodeum that makes a noticeable angle with the posterior region, and a shorter anterior margin of the petiolar node.

Etymology

The species name harenarum is a Latin plural noun in the genitive case of harena, which means sand. It is in reference to the littoral rainforest, the only habitat in which it has been found.

Differing from minor worker in the following characters: enlarged head (CS: 3.17±0.16; 2.94–3.48; CWb/CL: 0.94±0.03; 0.89–1.01) with broadly concave posterior margin; two apical teeth of mandible normally spaced; apical 1/4 of antennal scape surpassing posterior cephalic margin; robust mesosoma, metanotum distinctly visible, propodeal dorsum joining declivity in broad angle; dorsal margin of petiolar node inclined posteriorly from shorter anterior face towards much longer posterior face. More pairs of erect hairs on promesonotum, junction of propodeal dorsum and declivity, and posterodorsal margin of petiolar node.

Distribution and biology

Camponotus hova is a widespread species that occurs in dry forests of the west from the north throughout the center and the southwest of Madagascar, and is also known from Juan de Nova, Europa, and Mayotte islands (Fig. 58D). On these small islands, members of this species occupy coastal spiny bush on sand, spiny forest on coral, and coastal dune vegetation. This species is also capable of colonizing human-modified habitats. Workers are found foraging on the ground and nest sites are located in rotten logs, in the ground, and in rot pockets above the ground.

Figure 58.

Camponotus hova A lateral view B head in full-face view C dorsal view of minor worker CASENT0055710 D distribution map.

Discussion

Camponotus hova shows significant morphological variation across its wide distribution in Madagascar and nearby islands. Two variants are recognized according to the forms of the dorsum of the propodeum, but these merge gradually into the typical form through their geographical distribution.

Variant 1. Workers of this variant express the typical form by which the posterior 1/2 of the mesonotum to the posterodorsal corner of the propodeum is straight in profile. The petiolar node is characterized by the posterior inclination of the dorsal margin toward the anterior face, which is ca. 1/3 the height of the posterior face. This variant occupies the southwest region of Madagascar and surrounding islands. Integument is brown to dark brown or blackish brown in color.

Variant 2. This variant is known from the northwestern part of Madagascar and is characterized by the presence of a slightly broad concavity from the posterior 1/2 of mesonotum to posterodorsal corner of propodeum in lateral view and by the pale yellow to reddish orange color the body. Its petiole is nodiform, and the dorsal margin rounds to the anterior face, which is 1/2 height of the posterior face.

Based on the original description of C. hova (Forel, 1891) and C. hova obscuratus (Emery, 1925) and the examination of their respective syntype specimens, there are no distinctive characters that were found to differentiate both taxa. The observation of the collection obtained from the recent survey of the Malagasy ant fauna indicates that the distinctive characters of C. hova obscuratus vary within and across the populations of C. hova. Therefore, it is reasonable to place safely C. hova obscuratus in synonymy here.

Although qualitative morphology recognized the two variants in C. hova, the exploratory analysis of NC-clustering did not completely detect their distinction. The combination of the two variants is classified by confirmatory LDA at 100% of success.

Diagnosis

Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible normally spaced; antennal scape covered with suberect hairs; in lateral view, dorsum of mesosoma from mid-mesonotum to posterodorsal corner of propodeum approximately straight, propodeal dorsum ca. 3 × as long as the height of declivity surface; petiolar node flattened anteroposteriorly.

Description

Minor worker. Head sides anterior to level of eye parallel; lateral margins posterior to level of eye converging progressively to posterior margin; length of posterior portion of head behind eye level 1/3 length of head (PoOc/CL: 0.28±0.01; 0.25–0.31). Eyes protruding and large (EL/CS: 0.30±0.01; 0.27–0.34), breaking lateral cephalic margin. Frontal carinae strongly diverging posteriorly (FR/CS: 0.30±0.01; 0.28–0.33); clypeus projecting into anterolateral angle and medially with blunt angle or convex. Two apical teeth of mandible distantly spaced. Antennal scape relatively long (SL/CS: 1.54±0.08; 1.43–1.75) with erect to suberect hairs inclined to 45°. Promesonotum weakly convex and mesopropodeum almost flat, metanotal groove weakly visible, propodeal dorsum anteriorly convex and posteriorly flat, joining the declivity in a blunt angle, propodeal declivity height 1/2 dorsum length.

First and second gastral tergites without a pair of white spots. Lateral margin of head covered with erect hairs; posterior margin of head with two or three pairs of erect hairs; posterodorsal angle of propodeum with one or two pairs of erect hairs.

Major worker. Characteristics the same as minor worker, except the enlarged head (CS: 2.66±0.20; 2.40–3.07; CWb/CL: 0.77±0.02; 0.72–0.80); the more strongly built mandible; apical 1/5 of antennal scape surpassing posterior cephalic margin; metanotum visible; propodeal dorsum convex and its junction to declivity broadly angulate; petiolar node much higher than long.

Distribution and biology

A widely distributed species, C. hovahovoides occurs mainly in the eastern lowland to montane rainforests and montane shrublands of Madagascar (Fig. 59G). Colonies can be found mostly in rotten logs and sticks or in rotting tree stumps; they are seldom established in dead branches or twigs above the ground. Workers forage on the ground or through leaf litter, rarely on lower parts of vegetation.

Discussion

See also discussion under C. mixtellus. Camponotus hovahovoides is one of the more common species of Myrmosaga occupying the montane rainforests of Madagascar and shows notable morphological variation. Two variants are recognized based on the shapes of the mesosoma and body colors, but these merge progressively into one typical form across the geographic distribution of the species.

Variant 1. In this variant the posterior 1/2 of mesonotum to posterodorsal corner of propodeum is not straight in lateral view and the body is pale yellow to reddish orange in color.

Variant 2. This variant is known by a dorsum of mesosoma from mid-mesonotum to posterodorsal corner of propodeum that is approximately straight, and its body is dark brown to black in color or the mesosoma is lighter in color relative to the darker head and gaster. Workers of this variant have been collected from mountaintops.

Camponotus hovahovoides has a wide distribution across the humid forest in Madagascar, this information combined with the results of the comparison of the syntype specimens of C. radamae var. hovoides with those of C. hovahovoides indicate that there is no strong morphological difference between both taxa. The few specimens of C. radamae var. hovoides represent a rare variation of C. hovahovoides across its geographic distribution.

The NC-Clustering technique was used to reveal the two variants and demonstrates that the quantitative morphological characters did not identify the difference between both variants. The members of each variant are scattered along the cluster of C. hovahovoides. More robust molecular phylogenetic information is needed to determine whether the variants constitute separate species and to study the ecological and evolutionary forces underlying these morphological variations.

Camponotus imitator Forel

Fig. 16A (see Rasoamanana et al. 2017 for the description)

Diagnosis

With head in full-face view, posterior portion of head extending into a neck, and anteromedian clypeal margin continuously forming broad convexity; dorsal outline of mesosoma complex; body color black to dark brown.

Distribution and biology

See the geographic distribution and biology in Rasoamanana et al. (2017).

Discussion

Camponotus imitator can be easily separated from the other species of the Myrmosaga group in that it is the only species that is characterized by an elongate mesonotum that is constricted at midlength, and its propodeum is broadly convex when the mesosoma is viewed in profile.

See also discussion under the section “Morphological diagnosis of the worker caste of the Malagasy Myrmosaga”.

The grouping of C. imitator revealed by the NC-clustering method dendrogram is confirmed by the cumulative LDA at 100% identification success, indicating the support of the species hypothesized by qualitative morphology-based taxonomy.

Diagnosis

In full-face view, lateral margins of head anterior to eye level diverging posteriorly; anterior clypeal margin truncate; white spots absent on second and third abdominal tergite.

Description

Minor worker. With head in full-face view, lateral margins diverging towards almost straight posterior margin; eye slightly convex and small (EL/CS: 0.25±0.01; 0.23–0.28), not interrupting lateral cephalic border, level of its posterior margin located at ca. posterior 1/4 of head (PoOc/CL: 0.26±0.02; 0.22–0.28); frontal carinae wide, posteriorly diverging (FR/CS: 0.32±0.01; 0.30–0.33), distance between them larger than their smallest distance to eye; clypeus with bluntly angulate anterolateral corner and straight anteromedian margin; two apical teeth of mandible normally distant; antennal scape relatively short (SL/CS: 1.28±0.05; 1.19–1.34). Promesonotum evenly convex; posterior portion of mesonotum flat immediately anterior to weakly visible metanotal groove; propodeal dorsum strongly concave medially; junction of dorsal margin of propodeum with declivity bluntly angulate; propodeal dorsum ca. 2 × as long as declivity. Petiole nodiform, its dorsal margin inclined posteriorly and rounding to anterior margin; anterior and posterior faces almost the same height; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; erect hairs on lateral margin of head absent; two erect hairs present near posterior cephalic margin; antennal scape with appressed hairs only; pronotum and mesonotum with a pair of erect hairs each, posterodorsal angle of propodeum with a pair of erect hairs. Integument shining; body color dark brown; distal portion of leg reddish brown.

Major worker. Characteristics the same as minor worker, except the enlarged head (CS: 2.32±0.12; 2.13–2.46; CWb/CL: 1.00±0.03; 0.96–1.04), with slight concavity of posterior margin; anteromedian margin of clypeus noticeably concave; apical 1/4 of antennal scape extending beyond posterior cephalic margin; robust mesosoma, promesonotum convex, propodeal dorsum straight immediately posterior to metanotum, feebly concave towards declivity, length the same as height of declivity; petiolar node tapering dorsally.

Distribution and biology

Occupying the high plateau of Madagascar, C. immaculatus occurs in shrubland and grassland areas, montane rainforest, savannah grassland, and Uapaca woodland habitats (Fig. 60D). It is also known from rainforest and forest transitioning to montane forest in the southeast, and from human-modified habitats in the west, south, and high plateau of the island. Nest sites are typically established in the ground, under stones, and under rotten logs, while foraging is carried out in the leaf litter, on the ground, and on lower vegetation.

Figure 60.

Camponotus immaculatus A lateral view B head in full-face view C dorsal view of minor worker CASENT0082438 D distribution map.

Discussion

Camponotus immaculatus can be easily separated from C. kelimaso and C. lubbocki by the presence of the broad concavity on the propodeal dorsum. It also can be distinguished from other species because the anteromedian margin of its clypeus is truncate and no white spots are visible on the abdominal tergites.

When describing C. quadrimaculatus opacata, Emery (1925) did not make any comparative study with C. immaculatus. He stated no morphological characters that separate the former species from the later, and our examination of the syntype specimens of both taxa indicates that morphological variation observed in the former is found across the large geographical distribution of the latter. Hence, there is no doubt to make C. quadrimaculatus opacata under synonymy here.

The delimitation argument for C. immaculatus is strengthened by the congruence between the results of traditional qualitative morphology and the NC-clustering method. However, LDA produces a high 8.4% error rate in the classification of C. immaculatus, due to a misidentification of a single minor worker as C. quadrimaculatus. The high error rate is due in large part to the small range of minor worker forms of C. immaculatus available for this study.

Figure 62.

Camponotus karsti A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0217292 D distribution map.

Discussion

Camponotus karsti can be confounded with C. harenarum because both species are characterized by the presence of a blunt angle at approximately the posterior 1/2 of propodeal dorsum. However, C. harenarum can be distinguished by the separate convexity of its mesonotum and anterior 1/2 of propodeum, and its petiolar node is approximately as high as long.

Etymology

The species name karsti is a non-Latin singular noun used in apposition.

Diagnosis

In full-face view, lateral margins of head anterior to eye level diverging posteriorly; anterior clypeal margin truncate; dorsum of second and third abdominal tergites lacking white spot; propodeal dorsum straight; body color dark brown; antennal scape without erect hairs.

Description

Minor worker. In full-face view, head sides diverging towards anterior to level of eye, evenly rounding to approximately straight posterior margin; head widest at eye level; eyes almost flattened and small (EL/CS: 0.19±0.01; 0.16–0.21), not breaking lateral cephalic margin, level of posterior margin located approximately at posterior 1/3 of head (PoOc/CL: 0.28±0.01; 0.27–0.29); frontal carinae more or less wide (FR/CS: 0.31±0.02; 0.28–0.34), posteriorly diverging, distance between them smaller than their smallest distance to eye; clypeus with anterolateral angle and approximately straight anteromedian margin; mandible with two apical teeth distantly spaced; antennal scape relatively short (SL/CS: 1.19±0.05; 1.11–1.27). Promesonotum weakly convex; mesonotum with posterior portion flat immediately anterior to weakly visible metanotal groove; propodeal dorsum almost straight, its angle to declivity widely rounded; propodeal dorsum ca. 2 × as long as declivity. Petiolar node flattened anteroposteriorly, without obvious dorsal margin; anterior face almost the same height as posterior face; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral cephalic margin with erect hairs anterior to level of eyes; no erect hairs on lateral margin of head posterior to eye level; two erect hairs present near posterior margin; antennal scape only covered with appressed hairs; pronotum with few erect hairs; mesonotum with a pair of erect hairs; two erect hairs present on anterior to posterodorsal corner of propodeum. Body color reddish brown to pale brown.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 2.83±0.25; 2.35–3.15; CWb/CL: 0.99±0.04; 0.92–1.04) with broadly concave posterior margin; apical 1/4 of antennal scape surpassing posterior cephalic margin; robust mesosoma with separate convexity of promesonotum, lower position of metanotum and propodeum, propodeal dorsum approximately the same length as declivity surface and with rounded junction; petiolar node more flattened anteroposteriorly.

Distribution and biology

The distribution of C. kelimaso is limited to the eastern lowland rainforest of Madagascar between the Makirovana forest in the north and the Forêt d’Ambalagoavy Nord in the south (Fig. 63D). It nests mainly in rotten logs and rarely in root mat layers in the ground. Foraging is carried out on the ground and through leaf litter.

Figure 63.

Camponotus kelimaso A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0487718 D distribution map.

Discussion

Camponotus kelimaso can be separated from C. immaculatus by its straight propodeal dorsum. It can be differentiated from C. lubbocki by the approximately straight posterior margin of the head and its small compound eyes.

Based on the information provided by the NC-clustering method, the grouping of C. kelimaso supports the distinction of the species by conventional qualitative taxonomy. The confirmatory LDA identified the samples successfully at 100%.

Etymology

The species name kelimaso is a non-latin word derived from the Malagasy word for “small eye”. It refers to the fact that its compound eyes are small compared to those of other species in the subgenus Myrmosaga.

Camponotus liandia Rakotonirina & Fisher

Figs 34A, 64 (See Rakotonirina and Fisher 2018 for the description)

Diagnosis

In full-face view, lateral margins of head anterior to eye level diverging posteriorly; anterior clypeal margin broadly triangular.

Distribution and biology

In the present study, more samples have been attributed to C. liandia. The species is generally known from coastal scrub and littoral forest in the east, montane rainforest, grassland, shrubland, savannah grassland, woodland, and Uapaca woodland on the central high plateau (Fig. 64D). It has also colonized dry forest on tsingy and burned savannah in the west, degraded forest below granite outcroppings, and montane shrubland on rock in the high plateau. Nests are established in rotten logs, under stones, and in the ground. Workers may forage on the ground and on low vegetation.

Figure 64.

Camponotus liandia A lateral view B head in full-face view C dorsal view of minor worker CASENT0491145 D distribution map.

Discussion

With the additional samples, C. liandia presents two morphological variations: a matte integument covered with microreticulate sculpture, and a smooth and shining body. The first form has been observed from samples collected from the Forêt d’Atsirakambiaty in the grassland of the south-central high plateau. The second form occupies coastal scrub and littoral forest in the east and dry forest on Tsingy and burned savannah in the west.

Camponotus liandia was originally described under the subgenus Mayria (Rakotonirina and Fisher 2018) but the presence of a median carina on a broadly projected rectangular clypeus and a dorsally tapering petiolar node that are a few of the strong features characterizing the subgenus Myrmosaga has led to the placement of the species to this latter subgenus. The subgenus Mayria has generally rounded anterior clypeal margin and a nodiform petiole.

The cluster for C. liandia is composed of a larger number of worker samples to include the qualitative morphological variation within the species. The results of the exploratory analysis using NC-clustering methods are congruent with the definition of C. liandia based on traditional qualitative morphology. Identification of this species is confirmed by LDA with 100% success.

Diagnosis

With head in full-face view, lateral cephalic margins converging posteriorly towards eye level, then rounding to occipital corner of head; anteromedian margin of clypeus noticeably excised medially; two apical teeth of mandible normally spaced; lateral cephalic margin anterior to eye level covered with erect hairs.

Description

Minor worker. With head in full-face view, lateral cephalic borders anterior to level of eye parallel to each other, converging strongly towards posterior margin behind eye level; eye large and convex (EL/CS: 0.30±0.01; 0.27–0.31), breaking lateral margin of head, level of its posterior margin located approximately at posterior 1/3 of head (PoOc/CL: 0.29±0.01; 0.28–0.31); frontal carinae not widely opened (FR/CS: 0.26±0.01;0.25–0.27), posteriorly parallel, distance between them larger than smallest distance to eye; clypeus with anterolateral angle and medially slightly concave anteromedian margin; two apical teeth of mandible distantly spaced; antennal scape relatively long (SL/CS: 1.80±0.03; 1.76–1.85). Mesosoma long and low (MPH/ML: 0.29±0.01; 0.29–0.30), with its dorsal outline almost flat; metanotal groove feebly visible; propodeal dorsum feebly convex anteriorly and flat posteriorly; junction of propodeal dorsum to declivity bluntly angulate; propodeal declivity 1/3 length of the dorsum. Petiole nodiform, tapering dorsally; its dorsal margin inclined posteriorly and forming a blunt angle to anterior face; posterior face 2 × as high as the anterior; femur of hind leg rounded axially, without twist near base.

First and second gastral tergites without a pair of white spots; with head in full-face view lateral margin covered with erect hairs; near posterior margin of head with a pair of erect hairs; antennal scape covered with erect hairs inclined at ca. 45°; pronotum with numerous erect to suberect hairs; a pair of erect hairs present on posterodorsal angle of propodeum.

Major worker. Unknown.

Distribution and biology

Camponotus lokobe is endemic to Madagascar and restricted to the rainforest of the RNI Lokobe in the north of the island (Fig. 65D). Nest sites have been found in rotten logs.

Figure 65.

Camponotus lokobe A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0436584 D distribution map.

Discussion

Camponotus lokobe can be separated from C. dufouri and C. tendryi by the fact that its clypeus is characterized by a medially excised anteromedian margin.

The grouping of C. lokobe in the same cluster shown by the dendrogram of multivariate morphometric analysis is confirmed by the cumulative LDA at 100% identification success, corroborating the species hypothesized by the taxonomic revision based on qualitative morphology.

Etymology

The species name lokobe is a singular non-Latin noun used in apposition and refers to the type locality.

Camponotus lubbocki Forel

Figs 36B, 37B (See Rakotonirina and Fisher 2018 for the taxonomic history and redescription of the species)

Diagnosis

In full-face view, lateral margin of head anterior to eye level diverging posteriorly; anterior clypeal margin truncate; no white spot on dorsum of second and third abdominal tergites; body color black; antennal scape without erect hairs, propodeal dorsum slightly concave.

Distribution and biology

See the geographic distribution and biology in Rakotonirina and Fisher (2018).

Discussion

Camponotus lubbocki might be confused with C. liandia but the latter has a broadly convex anteromedian margin of the clypeus. It looks similar to C. immaculatus and C. kelimaso because they too lack white spots on the second and third abdominal segments, but in C. immaculatus the propodeal dorsum is transversely concave and in C. kelimaso the eyes are small and the posterior cephalic margin is approximately straight.

Forel (1912) originally placed C. lubbocki under the subgenus Myrmosaga, which was later synonymized by Emery (1925) under Mayria (see also Rakotonirina and Fisher 2018). Whereas this species was recently redescribed under Mayria, it is morphologically similar to those within Myrmosaga because of its broadly projected rectangular clypeus that is medially carinate, and a more or less anteroposteriorly flattened petiolar node. The subgenus Mayria is characterized by the clypeus that has no median carina, but with a rounded anterior margin, and a nodiform petiole. Therefore, C. lubbocki is moved back to the subgenus Myrmosaga here.

The species delimitation of C. lubbocki based on qualitative morphology is sustained by the NC-clustering method. Identification of this species is confirmed by LDA with 100% success (see also Rakotonirina and Fisher 2018).

Distribution and biology

Camponotus mahafaly is geographically restricted to dry forest and spiny bush and forest habitats of the southwest and south of Madagascar (Fig. 66D). Nest sites are generally located in rotten logs, and foraging occurs on the surface of the ground.

Figure 66.

Camponotus mahafaly A lateral view B head in full-face view C dorsal view of minor worker CASENT0115287 D distribution map.

Discussion

Camponotus mahafaly might be confounded with C. cemeryi because the petiole of both species is not nodelike, but in the latter species the antennal scape is covered with suberect hairs and the mesosoma is generally short and high, with a dorsal outline that is strongly convex.

The qualitative morphology-based study of this species agrees with the multivariate morphometrics to support the taxonomic determination of C. mahafaly. Separation of this species is confirmed by LDA with 100% success.

Etymology

The species name mahafaly is a singular non-Latin noun used in apposition and refers to the Mahafaly region in the southwest of Madagascar.

Diagnosis

Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible normally spaced; antennal scape covered with suberect hairs inclined at ca. 30°; in lateral view, posterior 1/2 of mesonotum to posterodorsal corner of propodeum somewhat convex, propodeal dorsum ca. 2 × as long as the height of declivity surface; petiolar node flattened anteroposteriorly.

Description

Minor worker. In full-face view, head sides anterior to level of eye parallel; lateral margins posterior to level of eye converging progressively to posterior margin; length of posterior portion of head behind eye level 1/3 length of head (PoOc/CL: 0.30±0.01; 0.28–0.31). Eyes protruding and large (EL/CS: 0.30±0.02; 0.27–0.33), breaking lateral cephalic margin. Frontal carinae not strongly diverging posteriorly (FR/CS: 0.28±0.01; 0.26–0.30) and posteriorly parallel; clypeus with anterolateral angle and its anterior margin with medial blunt angle or convex. Mandible with six teeth, two apical teeth normally placed. Antennal scape relatively long (SL/CS: 1.55±0.07; 1.40–1.73) with suberect hairs inclined 30°. Promesonotum weakly convex and mesopropodeum feebly convex (MPH/ML: 0.39±0.02; 0.36–0.42), posterior portion of mesonotum flat immediately anterior to metanotal groove, metanotal groove weakly visible, propodeal dorsum anteriorly convex and posteriorly flat, junction of dorsal margin and declivity with blunt angle, propodeal dorsum 2 × as long as the declivity. Petiolar node flattened anteroposteriorly or short and high, its dorsal margin rounding to anterior margin. Tibia of hind leg rounded.

First and second gastral tergites without a pair of white spots. Erect hairs on lateral margin of head anterior to level of eyes present, but absent posterior to level of eyes; posterior margin of head with two pairs of erect hairs; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 2.92±0.15; 2.62–3.10; CWb/CL: 0.93±0.03; 0.90–0.99), in full-face view with slightly concave posterior margin, eye not breaking lateral cephalic margin; apical 1/4 of antennal scape surpassing posterior cephalic margin; robust mandibles and mesosoma, metanotum distinctly visible; petiolar node tapering dorsally.

Distribution and biology

Camponotus mixtellus is a widespread species of the Malagasy region that occurs in the eastern lowland to montane rainforests and part of the western dry forests of Madagascar; it is known also from secondary rainforest and dry forest habitats of Grand Comore and Moheli of the Comoros islands (Fig. 67D). As this species is both arboreal and terrestrial, its members are commonly found foraging on low vegetation and on the ground, and nest in dead branches and twigs above the ground, in rotten logs and rotting tree stumps, in the ground, or under stones.

Figure 67.

Camponotus mixtellus A lateral view B head in full-face view C dorsal view of minor worker CASENT0076675 D distribution map.

Discussion

Camponotus mixtellus can be confused with C. hovahovoides, but the latter has a longer propodeal dorsum that is ca. 3 × as long as the declivity. It looks similar to C. boivini but the latter is characterized by an antennal scape covered with suberect hairs inclined at ca. 45°.

The cluster of C. mixtellus shown by the NC-clustering method is confirmed by the cumulative LDA at 100% identification success, indicating support of the species hypothesized by qualitative morphology-based taxonomy.

Diagnosis

With head in full-face view, lateral cephalic margin converging posteriorly towards eye level, covered with erect hairs anterior and posterior to eye level; anteromedian margin of clypeus broadly convex; two apical teeth of mandible normally spaced.

Description

Minor worker. In full-face view, head widest at midlength, lateral margins posterior to level of eye rounding evenly to posterior margin; eye large, slightly convex (EL/CS: 0.27±0.01; 0.26–0.30), not breaking lateral cephalic margin, level of its posterior margin located approximately at posterior 1/4 of the head (PoOc/CL: 0.28±0.02; 0.25–0.32); frontal carinae wide (FR/CS: 0.25±0.01; 0.24–0.28), distance between them larger than their distance to eye; clypeus with anterolateral angle and anteromedian margin with blunt or convex angle; mandible with two apical teeth distantly spaced; antennal scape relatively long (SL/CS: 1.70±0.11; 1.59–1.88). Promesonotum weakly convex, posterior portion of mesonotum flat immediately anterior to weakly visible metanotal groove; propodeal dorsum almost straight; dorsal margin of propodeum and declivity junction bluntly rounded; propodeal dorsum 2 × as long as declivity. Petiolar node short and high, its dorsal margin inclined posteriorly and joining anterior face in a blunt angle; anterior face 1/3 of height of the posterior; femur of hind leg rounded axially, without torsion near base.

First and second gastral tergites without a pair of white spots; erect hairs present on lateral margin of head, near its posterior margin bearing more than six erect hairs; antennal scape with suberect hairs inclined at ca. 30°, appressed hairs lacking; promesonotum covered with erect hairs; posterodorsal angle of propodeum with more than two erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 4.02±0.35; 3.69–4.61; CWb/CL: 0.92±0.08; 0.79–1.01); more robust mandible; apical 1/4 of antennal scape surpassing posterior cephalic margin; pronotum convex, mesonotum sloping towards metanotum, propodeal dorsum feebly convex and joining the declivity at a broad angle; petiolar node higher than long.

Distribution and biology

Camponotus niavo is geographically restricted to the transitional humid forest of Ampasindava Peninsula, the rainforests of the Galoko chain and RS Manongarivo, and the montane rainforest of the PN Montagne d’Ambre (Fig. 68D). Colony nests are established in rotten logs and rotting tree stumps, while foraging is carried out on the forest floor and through leaf litter.

Discussion

See discussion under C. cervicalis.

The qualitative, morphology-based analysis of this species agrees with the multivariate morphometric analysis to provide 100% support for the taxonomic determination of C. niavo.

Etymology

The species name niavo is a non-Latin singular noun used in apposition and is derived from the Malagasy word that means “from above”. It refers to the high mountains where the species has been collected.

Promesonotum slightly convex; posterior portion of mesonotum flat immediately anterior to feebly visible metanotal groove; propodeal dorsum immediately posterior to metanotal groove convex, medially strongly concave, then posteriorly flat, joining declivity at a remarkably visible angle; declivity height 3/4 length of dorsum. Petiolar node short and high, with dorsal margin inclined posteriorly and rounding to anterior margin; anterior face shorter than posterior face; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites with a pair of white spots; lateral margin of head lacking erect hairs; two erect hairs present close to posterior margin of head; antennal scape covered only with appressed hairs; pronotum with two and mesonotum with one pairs of erect hairs, respectively; posterodorsal corner of propodeum with a pair of erect hairs. Body color shining reddish black, dark brown to orange-yellow; apical portion of appendages pale in color.

Major worker. Differing from minor worker in the following characters: enlarged subquadrate head (CS: 2.44±0.14; 2.19–2.66; CWb/CL: 1.04±0.03; 1.00–1.08), with broadly concave posterior margin; anteromedian clypeal margin with median excision; antennal scape barely surpassing posterior cephalic margin; strongly built mandible; robust mesosoma, with distinct metanotum; propodeal dorsum slightly to strongly concave towards declivity surface; petiolar node scalelike.

Distribution and biology

Endemic to the Malagasy region, C. quadrimaculatus is known from Madagascar, the Comoros islands (Anjouan, Grand Comore and Moheli), and Mayotte (Fig. 69D). In Madagascar, this species is widely distributed across most of the terrestrial habitats of the island except spiny bush and thicket in the southern region. Camponotus quadrimaculatus is typically found from littoral rainforest and dry forest through rainforest and montane rainforests to savannah woodland habitats. It also can colonize human-modified habitats adjacent to its natural areas of distribution. The yellowish orange variant of the species has a range restricted to the northern part of Madagascar, where it occupies not only natural rainforest areas of the RS Manongarivo and the Galoko Montain Chains and the littoral rainforest of Nosy Faly, but also human-modified areas such as coffee plantations, urban garden habitats, and disturbed littoral rainforest habitats.

Discussion

Camponotus quadrimaculatus is similar to C. rotrae but in the latter the propodeal dorsum is straight.

The minor workers of C. quadrimaculatus display a remarkable range of phenotypic diversity. This assertion of the diversity of morphological characters is made on the basis of specimens with similar promesonotum shape, dorsal outline of the propodeal dorsum, and color of the body. However, the geographic range of differences among the observed variants does not follow a simple pattern. One variant of the yellowish orange body color has a restricted geographic boundary in the north of Madagascar, while others, showing variation in the strength of the concavity on the propodeal dorsum, are widely distributed along the rainforests of the island.

Across the wide geographic range of Camponotus quadrimaculatus, trait variations in the worker castes of C. quadrimaculatus sellaris, Camponotus kelleri and Camponotus kelleri var. invalidus have been observed. However, these variations do not present any pattern that separates them from the former species. Accordingly, C. quadrimaculatus sellaris, Camponotus kelleri and Camponotus kelleri var. invalidus are synonymyzed under Camponotus quadrimaculatus in present study.

Multivariate morphometric analysis through the NC-clustering method was applied to identify the presence of variants detected by the qualitative morphology-based study. However, NC-clustering did not reveal the existence of discrete variants. The samples from each of the variants are spread across the cluster of C. quadrimaculatus. Also, its classification success is only 97.2% because one of these samples was identified by LDA as C. gibber. This might be due to the fact that one of the variants belonging to this species is very similar to C. quadrimaculatus based on the qualitative morphology-based study.

Diagnosis

Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible closely spaced; lateral cephalic margin posterior to eye level without erect hairs; antennal scape covered with appressed hairs; mesosoma much higher and short, with propodeal dorsum 3 × as long as declivity; petiolar node more or less flattened anteroposteriorly and tapering dorsally.

Description

Minor worker. With head in full-face view, lateral margins anterior to eye level parallel, posteriorly rounding evenly towards short-necked rear margin; eye protruding and large (EL/CL: 0.31±0.01; 0.29–0.34), breaking lateral cephalic margin, location of its posterior margin at posterior 1/3 of head (PoOc/CL: 0.29±0.01; 0.27–0.31); frontal carinae widely opened posteriorly (FR/CS: 0.32±0.01; 0.30–0.34); clypeus with blunt or poorly defined anterolateral angle, anteromedian margin broadly convex; mandible with two apical teeth closely spaced; antennal scape relatively long (SL/CS: 1.52±0.07; 1.42–1.64). Mesosoma with weakly convex promesonotum (MPH/ML: 0.34±0.01; 0.31–0.36), posterior portion flat immediately anterior to metanotal groove; metanotal groove weakly visible, propodeal dorsum almost straight, junction of propodeal dorsum and declivity bluntly angulate, propodeal declivity almost 1/2 length of the dorsum. Petiolar node flattened anteroposteriorly, with dorsal margin rounding to anterior margin; tibia of hind leg rounded axially, without basal twist.

First and second gastral tergites without a pair of white spots; erect hairs on lateral margin of head anterior to level of eyes present but absent behind eye level; antennal scape covered with appressed hairs; posterior margin of head with two erect hairs; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 2.68±0.31; 2.29–3.02; CWb/CL: 0.95±0.04; 0.89–0.99) with broadly concave posterior margin; two apical teeth of mandible normally spaced; antennal scape barely surpassing posterior cephalic margin; robust mesosoma, metanotum distinctly visible, propodeal dorsum almost as long as the height of much more vertical declivity, their junction forming a broad angle; more pairs of erect hairs on promesonotum, junction of propodeal dorsum, declivity, and posterodorsal margin of petiolar node.

Distribution and biology

Endemic to Madagascar, Camponotus radamae normally occurs in eastern humid forests ranging from the littoral region to mountaintops (Fig. 70D). The species is arboreal and terrestrial, and nests in rotten logs, tree stumps, dead branches, twigs, and rot pockets above the ground, while its workers rarely forage on the ground and on lower vegetation.

Figure 70.

Camponotus radamae A lateral view B head in full-face view C dorsal view of minor worker CASENT0066777 D distribution map.

Discussion

Camponotus radamae is similar to C. vano in that the two apical teeth of their mandible are closely spaced, but C. vano has a more elongate body in which the mesosoma is very low and long, and its propodeal dorsum is at least four times as long as the declivity surface. In C. radamae the propodeal dorsum is 3 × as long as the declivity.

In Camponotus radamae the species definition is supported by the clustering shown by the dendrogram and confirmed by cumulative LDA at 100% classification success.

Diagnosis

In full-face view, lateral cephalic margins converging posteriorly towards eye level, posterior to eye level covered with erect hairs; two apical teeth of mandible closely spaced; head and gaster reddish black and mesosoma reddish orange or integument entirely reddish black.

Description

Minor worker. In full-face view, lateral margins slightly converging progressively towards level of anterior border of eye, strongly converging to a short posterior margin; eye large and broadly convex (EL/CS: 0.27±0.01; 0.25–0.29), breaking lateral cephalic margin, level of its posterior margin located at ca. posterior 1/3 of head (PoOc/CL: 0.28±0.01; 0.26–0.29); frontal carinae medially diverging (FR/CS: 0.24±0.01; 0.23–0.27), posteriorly parallel; clypeus without well-defined anterolateral angle, its anteromedian margin broadly convex, with anterolateral angle and anteromedian margin medially slightly concave; mandible with two apical teeth closely placed; antennal scape relatively long (SL/CS: 1.70±0.08; 1.50–1.81). Pronotum and anterior section of mesonotum weakly convex, posterior portion of mesonotum flat immediately anterior to a barely visible metanotal groove; propodeal dorsum anteriorly convex and posteriorly flat, rounding to declivity; propodeal dorsum ca. 3 × as long as declivity. Petiolar node approximately conical or with short anterior face and posteriorly inclined dorsal margin; femur of hind leg axially rounded, not twisted basally.

First and second gastral tergites without a pair of white spots; head with numerous erect hairs on lateral margin, more than six erect hairs present near its posterior margin; antennal scape covered in suberect hairs inclined at ca. 30°; promesonotum, posterior portion of propodeum, and higher level of declivity covered with more or less long, erect hairs.

Major worker. With characteristics of minor worker except: broader head (CS: 14.07±0.19; 3.81–4.40; CWb/CL: 0.89±0.04; 0.85–0.96), apical 1/3 of antennal scape extending beyond posterior cephalic margin; two apical teeth of mandible normally spaced, usually area ranging from third to basal teeth of mandible divided into two teeth or denticles; mesosoma very robust, promesonotum and metanotum forming even convexity, propodeal dorsum forming separate convexity and rounding to a short declivity surface; petiolar node more flattened anteroposteriorly. Hairs numerous and shorter on body dorsum.

Distribution and biology

As an endemic and widespread species of Madagascar, C. roeseli generally occurs in the western portion of the island in areas ranging from littoral and rainforest habitats in the north to dry forest areas in the west-central region through spiny forest and thicket in the south (Fig. 71G). This species is also known to occupy savannah, Uapaca woodland, montane rainforests, and human-modified habitats of the south-central high plateau. Foraging behavior is mostly carried out on the ground surface and infrequently on low vegetation, while nests are located mainly in rotten logs, in the ground, and under stones, and rarely in rotting tree stumps and under root mat-litter on rocks.

Figure 71.

Camponotus roeseli A, C head in full-face view B, D lateral view E, F dorsal view of minor workers CASENT0492473 and CASENT0179449 G distribution map.

Discussion

Camponotus roeseli might be confused with C. daraina because of the presence of erect hairs on the lateral margin of the head posterior to the eye level; however, the latter species can be distinguished by the reddish orange color of the entire body.

The species name C. roeseli and the subspecies name C. maculatus legionarium were created and described by Forel (1910) and Santschi (1911b), respectively, based on major worker specimens. However, observations of the type specimens of the species and subspecies reveal no robust morphological characters to distinguish them. Samples of the minor workers for C. roeseli show striking morphological variation along the western dry forest of Madagascar, especially in body coloration that ranges from dark brown to black through the head; brown gaster; and mesosoma, petiolar node, and the basal portion of the legs yellowish orange. This indicates morphological variation of major workers within the species is likely. Therefore, C. maculatus legionarium is presently synonymized under C. roeseli.

The taxonomic identity of C. roeseli established by conventional qualitative morphology is supported by multivariate statistical methods. The grouping of samples of this species achieved by the NC-clustering method is confirmed by LDA with an identification success of 100%.

Distribution and biology

Endemic to Madagascar, C. rotrae is geographically limited to the south-central high plateau of Madagascar. The species occupies montane rainforests of the PN Andringitra, gallery forest and grassland of the PN Isalo, savannah woodland of Itremo, and relict montane rainforest of the Forêt Classée d’Analavelona (Fig. 72D). The species nests mainly in rotten logs and under stones. Based on collection data, workers most often forage on the ground and rarely on lower vegetation.

Diagnosis

With head in full-face view, lateral cephalic margins converging posteriorly towards eye level; anteromedian margin of clypeus broadly convex; two apical teeth of mandible normally spaced; lateral cephalic margin anterior to eye level without erect hairs.

Description

Minor worker. In full-face view, lateral margins of head converging progressively to level of anterior ocular margin, strongly converging to a short posterior margin behind eye level; eye protruding and large (EL/CS: 0.28±0.01; 0.27–0.29), breaking lateral cephalic border, level of its posterior margin at least at posterior 1/3 of head (PoOc/CL; 0.32±0.04; 0.30–0.42); frontal carinae wide (FR/CS: 0.22±0.0; 0.21–0.23), posteriorly parallel, distance between them larger than smallest distance to eye; clypeus without well-defined anterolateral angle, its anteromedian margin broadly convex or triangular; mandible with two apical teeth closely spaced; antennal scape relatively long (SL/CS: 2.04±0.07; 1.97–2.18). Mesosoma low and long (MPH/ML: 0.33±0.03; 0.28–0.36), with weakly convex promesonotum and approximately flat mesopropodeum; metanotal groove barely visible; propodeal dorsum almost straight or anteriorly slightly convex and posteriorly flat; dorsal margin of propodeum and declivity joined at blunt angle; propodeal declivity 1/3 of length of dorsum. Petiole nodiform, dorsal margin inclined posteriorly, its junction to anterior face bluntly angulate; anterior face of petiolar node 1/2 height of posterior face; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral margin of head without erect hairs; two erect hairs present near posterior cephalic margin; antennal scape without erect hairs but covered with numerous appressed hairs; pronotum with a pair of erect hairs; posterodorsal angle of propodeum without erect hairs.

Major worker. Differing from minor worker in the following characters: larger head (CS: 4.45; CWb/CL: 0.98); apical 1/4 of antennal scape extending beyond posterior cephalic margin; very robust, short, and high mesosoma, with promesonotum and metanotum forming an even convexity; and propodeal dorsum sloping and joining declivity with blunt angle. Petiolar node much compressed anteroposteriorly, anterior face shorter than posterior.

Distribution and biology

Camponotus sambiranoensis is only known to occur in the north of Madagascar. It colonizes the dry forests of Binara, RS Ambre, and RS Ankarana, the transitional forests of Ampasindava and Binara, the rainforests of Makirovana and RS Manongarivo, and the montane forest of RS Manongarivo (Fig. 73D). This species nests in rotten logs and in the ground, and forages on the ground, in leaf litter, and on low vegetation.

Discussion

Camponotus sambiranoensis shares a broadly convex anteromedian margin of clypeus with C. niavo, and C. cervicalis, but in the two latter species the lateral cephalic margin anterior to the eye level is covered with erect hairs.

The qualitative, morphology-based delimitation of C. sambiranoensis is confirmed by the multivariate morphometric technique. The validity of the species is also confirmed by LDA at 100% classification success.

Etymology

The species name sambiranoensis is a Latin singular adjective in the nominative case of masculine gender. This species name refers to the region of Sambirano where the species was found.

In full-face view, head sides anterior to eye level parallel, converging strongly towards posterior margin behind eye level; eye convex (EL/CS: 0.28±0.01; 0.26–0.30), breaking lateral cephalic margin, level of its posterior margin located approximately at posterior 1/3 of head (PoOc/CL: 0.27±0.01; 0.26–0.29); frontal carinae close, distance between them equal to or smaller than their smallest distance to eye (FR/CS: 0.25±0.01; 0.24–0.27); clypeus with anterolateral angle and an almost straight or bluntly angulate anteromedian margin; two apical teeth of mandible normally spaced; antennal scape relatively long (SL/CS: 1.58±0.05; 1.50–1.66). Mesosoma low and long (MPH/ML: 0.33±0.01; 0.31–0.36); promesonotum weakly convex, mesonotum and propodeum nearly flat, separated by weakly visible metanotal groove; propodeal dorsum rounding to declivity; propodeal dorsum roughly 2 × as long as declivity. Petiolar node tapering dorsally, its dorsal margin inclined posteriorly, rounding to anterior margin; anterior face 1/2 height of posterior face; femur of hind leg rounded axially, not twisted near base.

First and second gastral tergites without a pair of white spots; lateral margin of head without erect hairs; a pair of erect hairs present near posterior cephalic margin; with head in profile, three pairs of erect hairs arranged from level of anterior margin of eye to posterior cephalic margin; antennal scape without erect hairs, covered with distantly spaced pubescence; pronotum with two pairs of erect hairs; mesonotum and propodeum without erect hairs.

Major worker. With characteristics of minor worker, except for the following divergent features: enlarged head (CS: 3.22±0.36; 2.73–3.74; CWb/CL: 0.91±0.06; 0.80–0.98), apical 1/4 of antennal scape surpassing posterior cephalic margin, much more robust mesosoma, promesonotum forming a convexity, separated from propodeum by a distinct metanotum; propodeal dorsum convex immediately behind metanotum, length almost equal to height of declivity, their junction at a rounded angle; petiolar node tapering dorsally.

Distribution and biology

Endemic to the Malagasy region, C. strangulatus occurs in Grand Comore and Moheli of the Comoros islands, in Mayotte, in Aldabra of the Seychelles, and in Madagascar (Fig. 74D). In the Comoros and Mayotte this species occupies mangrove and coastal dry forest scrub, while in the Seychelles it also inhabits forest habitats. Regarding the distribution of C. strangulatus in Madagascar, it is found in rainforest and littoral rainforest in the north, in dry forest in the west, in spiny forest and thicket in the south, in montane rainforest and Uapaca woodland on the south-central high plateau, and in human-modified habitats in its southern range. It also occurs in littoral vegetation on Juan de Nova Island. Due to its capacity to colonize different types of habitats, C. strangulatus also builds nests in a large array of microhabitats such as rotten logs and rotten sticks on the ground, dead branches and dead twigs above the ground, under stones, and in the ground. Workers forage on the forest floor, in leaf litter, and on lower vegetation.

Discussion

Camponotus strangulatus may be difficult to distinguish from C. tapia and C. atimo but the dorsum of the head in the latter species bears four or more pairs of erect hairs arranged successively from the level of the anterior ocular margin towards the posterior cephalic margin.

As generally known, the genus Camponotus displays polymorphism in the worker castes and this feature is amplified by the phenotypic variation within the castes when the species has specifically a large geographic distribution. This is especially true for C. strangulatus which inhabits most of the terrestrial landscapes, but not the rainforests in the east of Madagascar. Camponotus hova maculatoides, created by Emery (1920b) was found in Nosibe, north of Madagascar, an area within the range of C. strangulatus. Observations of the type specimens of the species and subspecies prove the absence of strong morphological traits to differentiate them. The comparison of the type specimens of C. hova maculatoides with the samples of workers for C. strangulatus did not show striking morphological difference. Consequently, C. hova maculatoides is placed under synonymy here.

Species delimitation of C. strangulatus on the basis of traditional taxonomic study is congruent with the results of the NC-clustering method. The species was also classified correctly at 100% by confirmatory LDA.

Discussion

See discussion under C. atimo.

In the present study, the definition of C. tapia is based on both qualitative morphological analysis and morphometrics, which are congruent. The grouping of the samples of this species obtained from the NC-clustering is confirmed by LDA with an identification success of 100%.

Etymology

The species name tapia is non-Latin singular noun used in apposition and refers to the Malagasy name for Uapaca in reference to the type of habitat where the ant was most frequently found.

Distribution and biology

A species endemic to Madagascar, C. vano is geographically restricted to the PN Zahamena and the Corridor Forestier Analamay-Mantadia in humid forests in the east of the island (Fig. 77D). Collection data indicate that the species is arboreal; nests have been found in dead bamboo on the ground, while workers have been found foraging on lower vegetation.

Figure 77.

Camponotus vano A lateral view B head in full-face view C dorsal view of holotype minor worker CASENT0217316 D distribution map.

Discussion

See discussion under C. radamae.

Camponotus vano was not included in the NC-clustering analysis due to an inadequate number of minor workers. However, its qualitative morphological traits are sufficient to supports its status as a real species.

Etymology

The species name vano is a non-Latin singular noun used in apposition and refers to the Malagasy name for “heron”. It refers to the elongate body form of the species.
