Abstract

Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly unless a phylogenetically unrelated species is excluded (explained further on). A new classification is proposed for the seven species left in the genus and considered valid, of the 13 nominal species previously recognized. Two out of the seven valid species are considered as species inquirendae: Sadocus allermayeri (Mello-Leitão, 1945) [= Carampangue allermayeri Mello-Leitão, 1945] and Sadocus nigronotatus (Mello-Leitão, 1943) [= Carampangue nigronotatum Mello-Leitão, 1943]. The following synonymies are proposed: Sadocus bicornis (Gervais, 1849) [original combination = Gonyleptes bicornis Gervais, 1849] is a junior synonym of Sadocus asperatus (Gervais, 1847) [= Gonyleptes asperatus Gervais, 1847]; Sadocus conspicillatus Roewer, 1913, Sadocus exceptionalis (Mello-Leitão, 1946) [= Araucanoleptes exceptionalis Mello-Leitão, 1946] and Sadocus guttatus Sørensen, 1902 are junior synonyms of the valid name Sadocus polyacanthus (Gervais, 1847) [= Gonyleptes polyacanthus Gervais, 1847]; and Sadocus calcar (Roewer, 1913) [= Lycomedes calcar Roewer, 1913] is a junior synonym of the valid name Gonyleptes horridus Kirby, 1819. Sadocus brasiliensis Soares & Soares, 1949 is not congeneric with Argentinean/Chilean species of the genus according to the cladistic analysis and is here synonymized with Discocyrtus catharinensis (Mello-Leitão, 1923 [= Sadocus catharinensis Mello-Leitão, 1923]).

Introduction

Harvestman systematics has advanced greatly in the last few decades, especially in the Neotropical region, with many supraspecific groups being recently revised, such as for example Stygnidae Simon, 1879 (Pinto-da-Rocha 1997), Sodreaninae Soares & Soares, 1985 (Pinto-da-Rocha and Bragagnolo 2010), Goniosomatinae Mello-Leitão, 1935 (DaSilva and Gnaspini 2010), Hernandariinae Sørensen, 1884 (DaSilva and Pinto-da-Rocha 2010), among others. Gonyleptidae Sundevall, 1833, the largest Neotropical family in number of species, includes two taxonomically challenging and species-rich subfamilies pending revision: Gonyleptinae Sundevall, 1833 and Pachylinae Sørensen, 1884. The lack of revisions is possibly due to the considerable number of species and their great morphological variation.

Pachylinae is the most species-rich subfamily of Gonyleptidae, and is currently considered polyphyletic (Pinto-da-Rocha 2002; Pinto-da-Rocha et al. 2014; Benavides et al. 2021). A phylogenetic analysis, based on molecular data (Pinto-da-Rocha et al. 2014), recovered a clade including Pachylus Koch (1839), the type genus of the subfamily. This clade was named Pachylinae sensu stricto and includes mainly Chilean species. This result was the first step towards the dismemberment of this large subfamily into smaller monophyletic units.

The sister group of Pachylinae sensu stricto is a clade that includes the genus Sadocus Sørensen, 1886, composed of rather large-sized (5.5–13.8 mm of dorsal scutum length) and colorful harvestmen. Although conspicuous and relatively common in Chilean preserved areas, it was never revised in more than 130 years of existence. Historically (see below), the genus has been subjected to many taxonomic acts, resulting in confusing species identities. One has to use poor (for modern standards), hundred-year-old descriptions to identify a given species. In addition, similar species are difficult to distinguish, raising doubts about their identities. Therefore, the revision of Sadocus focuses on determining the identity of the included species, which in turn will allow further understanding of their relationships, and more precise inferences of their distribution and diversity (Acosta 2002). The goals of this article are also to test the monophyly of the genus and propose a classification based on cladistic analysis.

Historical aspects of Sadocus Sørensen, 1886

The history of Sadocus Sørensen, 1886 can be quite confusing because many of its species were described before the proposition of the genus. Therefore, this historical section mentions many species in different genera and subfamilies that were later transferred to Sadocus (Kury 2003; Kury et al. 2020a, b), as explained further on in this article.

Guérin-Méneville (1844) described the eldest species related to Sadocus, Gonyleptes planiceps in Cuvier’s ‘Iconographie du Règne Animal’. However, the publication of this issue was delayed, and Gervais’ (1842) “redescription” was actually published first. Gervais (1842) did credit the authorship of G. planiceps to Guérin-Méneville, and he redescribed that species in 1844. Gervais also described the next five species relevant to Sadocus: Gonyleptus asperatus, G. polyacanthoides, and G. polyacanthus in 1847, and G. bicornis and G. subsimilis in 1849. Butler (1873) mistakenly proposed G. subsimilis as a senior synonym of G. polyacanthoides. A year later, Butler (1874) described Gonyleptes funestus. In 1884, Simon transferred G. planiceps to Pachylus.

In 1886, Sørensen proposed the monotypic genus Sadocus, to include the type and new species S. vitellinosulcatus. In 1899, Loman described Discocyrtus calcitrosus and Gonyleptes platei, which are relevant to Sadocus, and transferred G. funestus to Discocyrtus Holmberg, 1878.

In 1902, Sørensen: (i) synonymized S. vitellinosulcatus and G. platei Loman, 1899 with G. polyacanthus; (ii) created the new genus Lycomedes (without indication of a type species), to which he transferred G. asperatus, G. bicornis, D. calcitrosus, D. funestus and Pachylus planiceps; and (iii) described Sadocus guttatus. On that paper, Sørensen placed these species in Gonyleptidae, but without assigning them to any subfamily. Therefore, at the beginning of the 20th century, named species relevant to Sadocus were placed in both Sadocus, comprising two species (S. polyacanthus and S. guttatus) and Lycomedes, with five species (L. asperatus, L. bicornis, L. calcitrosus, L. funestus and L. planiceps).

Roewer (1913) designated L. asperatus as the type species of Lycomedes, and placed it in the Pachylinae. In that same work, he: (i) proposed the synonymy of G. subsimilis and L. calcitrosus with L. asperatus; (ii) described Lycomedes calcar; (iii) placed Sadocus in the Gonyleptinae and described S. dilatatus and S. conspicillatus. In his large work of 1923, Roewer proposed Lycomedicus as a replacement name for Lycomedes, which was preoccupied, and described as new the genus Eubalta.

Mello-Leitão (1937) described the genus Carampangue for his new species C. ingens, placing it in the Pachylinae, and in 1943, he described C. nigronotatum. In that same year, Roewer (1943) described the monotypic genus Jighas for the new species J. vastus, and placed it in the Pachylinae.

In 1945, Mello-Leitão described Carampangue allermayeri, and in the next year (1946), he described Araucanoleptes for the new species A. exceptionalis, and placed it in the Gonyleptinae. A few years later, Mello-Leitão (1949) synonymized J. vastus with the older Carampangue ingens. In that same year, Soares and Soares (1949) described Lycomedicus brasiliensis, and later, H. Soares (1968) transferred Sadocus dilatatus to Lycomedicus. During the next 30 years, only few catalogues (Cekalovic 1968, 1976, 1985) mentioned the species related to Sadocus. 154 years after its first description, Acosta (1996) studied the collection of type material of Pachylinae described by Roewer and found differences between Guérin-Méneville’s (1844) description of L. planiceps and the redescription by Roewer (1913).

At the beginning of the 21st century (prior to this study), species relevant to Sadocus were placed in the following genera and subfamilies: the monotypic Araucanoleptes (Gonyleptinae); Carampangue (Pachylinae), with three species (C. allermayeri, C. ingens and C. nigronotatum); Lycomedicus (Pachylinae), with seven species (L. asperatus, L. bicornis, L. brasiliensis, L. calcar, L. dilatatus, L. funestus and L. planiceps); and Sadocus (Gonyleptinae), with three species (S. conspicillatus, S. guttatus, and S. polyacanthus).

Kury (2003), in his complete catalogue of New World Laniatores, proposed the synonymy of Lycomedicus, Carampangue, and Araucanoleptes with Sadocus. Hence, Sadocus comprised 14 species (actually, there are entries for 15 species, but that of S. subsimilis is clearly a mistake, which should be listed as a junior synonym under S. asperatus). Finally, Pessoa-Silva et al. (2020), transferred S. planiceps to Eubalta. Sadocus hitherto was composed of 13 species (Kury et al. 2020b). In the present publication, we accept only seven species of Sadocus as valid.

The topological nomenclature follows Acosta et al. (2007), nomenclature of integumentary ornamentation of dorsal scutum and legs, dorsal scutum outline and ventral plate penial macrosetae follows DaSilva and Gnaspini (2010), Kury and Medrano (2016) and Kury and Villarreal (2015), respectively. Nomenclature of ovipositor morphology generally follows Townsend et al. (2015). We adopted the orientation of the captured images to reference the ovipositor lobes, because we had no topological reference after detaching it. It is unlike the penis, which has a sclerotized ventral feature, thus being easily referenced topologically. In Sadocus, we realized that leg IV is twisted retro-laterad from the trochanter (gradually untwisting along the femur), rendering the otherwise prolateral structures as dorsal (Fig. 3A, E). To standardize the topological nomenclature, we opted to consider (and call) those as prolateral, despite being functionally dorsal (in situ). We illustrated the external morphology using a stereomicroscope with a camera lucida and the material immersed in 70% ethanol. We prepared male and female genitalia according to Pinto-da-Rocha (1997) to take pictures using a scanning electron microscope (SEM) or to illustrate using a compound microscope with a camera lucida. The generic characteristics are not repeated in the specific (re)descriptions. Only characters differing from those of the males are listed in the female (re)descriptions. The variation on the number of tubercles on the dorsal scutum and other parts of the body or legs were included in the intraspecific variation. The color descriptions are based on specimens preserved in 70% ethanol and living photograph examples presented in the section “variation in males (or females)” under each species. Many species of Sadocus present a white patch on the body, commonly known as a dry-mark (Kury in DaSilva and Gnaspini 2009). It is an external serose layer of the cuticle that often forms white patches/shapes. Distribution maps for Sadocus species were prepared using QGIS 3.10 (QGIS.org 2019). The identification key is only for males. Synonymic listings follow Kury’s catalogue (2003), to which we add the category of its content between parentheses (see abbreviations section above). All measurements are in millimeters. We followed the view of Kury et al. (2020a) regarding the use of the correct inflection of specific epithets that are adjectives throughout the article to avoid inviting further confusion for the reader. Therefore, despite Kury himself (2003) proposing the combination Sadocus funestis (Butler, 1874), we use Sadocus funestus (Butler, 1874) as Kury et al. (2020b) in all sections (except for synonymic listing), including the historical aspects of Sadocus.

We chose the outgroups based on available hypotheses including Pachylinae, such as Pinto-da-Rocha et al. (2014), Hara et al. (2012) and Hara (2016). We rooted the tree in Stygnidae (Stygnus polyacanthus (Mello-Leitão, 1923)) based on Kury (1994). We added other taxa to account for the morphological diversity of Pachylinae sensu stricto and its sister group.

We include records of distribution in maps only for vials with males. We used LibreOffice Calc to edit the character matrix and TNT 1.0 (Goloboff, Farris and Nixon 2008) to perform an implicit enumeration search under parsimony using equal weights. No character was ordered. We calculated Absolute and Relative Bremer support (Bremer 1994) to evaluate the support of clades using the Bremer Support Script for TNT 1.0 written by Pablo Goloboff (available at http://tnt.insectmuseum.org/index.php/Scripts/bremer). We used Winclada 1.00.08 (Nixon 1999) to edit the tree under ACCTRAN optimization and the notation of taxon+ proposed by Amorim (1982).

Results and discussion

Cladistic analysis

To test the monophyly of Sadocus, we used a matrix of morphological characters composed of 18 taxa (13 outgroups and five ingroups) and 64 characters (Table 1). The 64 characters are distributed as follows: 18 from dorsal scutum, four from free tergites, one from the chelicera, 23 from male legs, 17 from male genitalia, and one from coloration. We only included the valid Sadocus species with known males, as most of the characters are based on armature of male leg IV and penis. The cladistic analysis resulted in a single most parsimonious tree (182 steps, L = 182; C.I. = 45; R.I. = 53, Fig. 1).

According to the retrieved tree, Sadocus is not monophyletic, as it excludes Sadocus brasiliensis (Soares & Soares, 1949). Acosta (2020) first mentioned that S. brasiliensis may not belong to this genus based on the overall distribution of the other Sadocus species. That suspicion is corroborated here, and we propose its synonymy with the Brazilian Discocyrtus catharinensis (Mello-Leitão, 1923) (see taxonomic notes in this species’ entry). In turn, the close relationship of D. catharinensis with Roeweria bittencourti (Roeweriinae Brazilian species) is supported by seven synapomorphies, three of them exclusive: hexagonal shape of the penial ventral plate [49(1)]; penial ventral process apex tapering distally, becoming rolled [57(1)]; and penial stylus with latero-apical projections [59(1)]. Discocyrtus catharinensis is probably a Roeweriinae especially based on the shape of the penial ventral plate as well as the overall penial morphology. However, we refrained further taxonomic actions as Roeweriinae diversity grows further fueled by the dismemberment of Discocyrtus, which is currently under revision (Kury and Carvalho 2016; Carvalho and Kury 2018, 2021).

Once we settled the issue related to S. brasiliensis, we propose a new concept of Sadocus. Under the new definition, Sadocus is monophyletic and supported by seven synapomorphies, four of which are exclusive: leg IV twisted from the trochanter to patella [28(0)]; trochanter IV with a finger shaped, robust prodorsal apical apophysis, its basal half of ca. uniform diameter [32(3)], trochanter IV twice longer than wide [37(1)] (modified from Hara 2016); and penis ventral plate with slightly concave distal margin [47(1)]. Sadocus is also the best supported clade of the analysis, with a high Goodman-Bremer support (4).

So far, Sadocus (represented especially by S. polyacanthus, its type species) has often been used in cladistic analysis as outgroups (Hara et al. 2012; Hara 2016) or as an ingroup taxon of a more comprehensive analysis testing monophyly of Gonyleptidae or Gonyleptoidea (Pinto-da-Rocha et al. 2014; Benavides et al. 2021). According to the analyses based on morphological characters (Hara et al. 2012; Hara 2016), Sadocus is nestled in a clade mainly composed of Brazilian species. However, we have to stress that the clade with Sadocus in Hara’s analyses is not well supported (Bremer support: 1), its sole homoplastic synapomorphy being the proventral apical armature of tibia IV as a tubercle. In the present analysis, we have a roughly similar outcome, as the clade including Sadocus (Sadocus + Neogonyleptes) is sister group to a clade composed of solely Brazilian species. This outcome differs considerably from Pinto-da-Rocha et al. (2014) or Benavides et al. (2021): in those analyses based on molecular data, Sadocus is often retrieved closely related to Chilean Pachylinae genera. Regarding this, Pinto-da-Rocha et al. (2014) indicate that Sadocus is in a clade with other Chilean species (Neogonyleptes karschii and Tumbesia aculeata), which in turn is sister group to Pachylinae sensu stricto. Benavides et al. (2021) also corroborates a close relationship of Sadocus with Chilean genera.

The sister taxon closest to Sadocus is also an unsettled issue, mainly because different taxa are employed in those analyses. In the present analysis, Sadocus sister group is the Chilean genus Neogonyleptes, supported by seven synapomophies, two of them exclusive: ventral row of granules increasing in size apically on tibia IV [46(1)]; and apex of glans ventral process flattened circle shaped [57(2)]. This sister group relationship is similar to Pinto-da-Rocha et al. (2014) sampling wise. On the other hand, Benavides et al. (2021) did not include Neogonyleptes in their analysis, and the Chilean Eubalta planiceps is the sister taxon to Sadocus. It is interesting to note that Sadocus sister taxon is strongly affected by the Chilean Pachylinae sampling not belonging to Pachylinae sensu stricto.

The main goals of this study were to revise and to test the monophyly of Sadocus, a hundred-year-old genus, with a convoluted taxonomic history. We believe that we succeeded in those, and the present study is an important step towards the understanding the evolution of the genus. Considering all the evidence (including the taxonomic history), Sadocus seems to be related to the Chilean-Argentinean Pachylinae. We understand that Sadocus relationship within Gonyleptidae is still an unsettled issue that deserves further investigation. As a mean to tackle that, we can suggest the inclusion of more Chilean Pachylinae genera (especially those already used in previous analyses and not belonging to Pachylinae sensu stricto) and Brazilian species as well, such as DRMN (Carvalho and Kury 2018) and K92 (Kury 1992). The latter suggestion is because of the Brazilian clade closest to Chilean Pachylinae clade depicted by Pinto-da-Rocha et al. (2014) and Benavides et al. (2021).

Diagnosis

Sadocus are large Pachylinae (dorsal scutum maximum length 5.5–13.8 mm) with paired spines on ocularium and prominent frontal hump on dorsal scutum anterior margin. Dorsal scutum shape types gamma triangular and gamma pyriform, its posterior margin concave. Dorsal scutum mid-bulge placed close to scutal groove IV (scutal groove III in S. funestus) and transversal (S. funestus, S. ingens, S. polyacanthus) or oblique (S. asperatus, S. dilatatus); free tergites II and III each with a pair of spines. Legs IV are twisted retro-laterad from the trochanter and gradually distorted along the femur and patella (except in S. funestus). Coxa IV bearing a long, large prodorsal apical apophysis and a short, retro-apical one (except in S. funestus, in which is lacking). Trochanter IV with a short, blunt prolateral sub-basal apophysis and a long, robust prodorsal apical one. Penis glans turgid and dorsally projected (with antero-lateral projections), with ventral process (half stylus length) and without dorsal process. General color (in living specimens) of the body and most parts of legs and ventral area dark brown, with lighter tones at the tips of podomeres. Yellowish to reddish tone in scutal area, scutal posterior margin, free tergites, part of legs and apophysis. Green on the arthrodial membranes between the free tergites.

Redescription

Male: Dorsum. Anterior margin of carapace with a prominent median frontal hump (bell shaped in dorsal view). Ocularium with one pair of spines posterior to the eyes. Dorsal scutum type varying from gamma to gamma triangular and gamma pyriform, its posterior margin concave, mid-bulge slightly asymmetrical and displaced posteriorly, widest at the scutal groove IV (scutal groove III in S. funestus). The curvature of mid-bulge can be transversal (S. funestus, S. ingens, and S. polyacanthus) or oblique (S. asperatus and S. dilatatus). Four scutal areas (three in S. polyacanthus); scutal area I divided into right and left halves by a longitudinal median groove. Scutal area III with one pair of paramedian spiniform tubercles or spines. Two pairs of ozopores close to coxa II. Lateral margin of dorsal scutum with an external and internal rows of tubercles (the external row of slightly larger tubercles) (except S. asperatus, with granules covering most of the lateral margin of dorsal scutum and S. ingens, smooth or with only few granules). Posterior margin of dorsal scutum and free tergite I each with one paramedian pair of tubercles (except S. funestus and S. polyacanthus, unarmed). Free tergites II and III each with one paramedian pair of spines. Venter. Coxa I–IV granulate; coxa I with a median longitudinal row of granules increasing in size apically, becoming tubercles. Chelicerae. Isomorphic in males and females. Segment I with well-marked bulla. Segment II fixed finger and segment III toothed. Pedipalps. Trochanter dorsal face inflated; ventral face with one or two setiferous tubercles. Femur bearing sub-apical mesal seta; dorsal face with few granules; ventral face with one basal setiferous tubercle. Tibiae and tarsi dorsal and lateral faces with few minute granules and variable setation. Legs. Coxae I–III each with one prodorsal and one retro-dorsal spiniform tubercles, ventral faces granulate (except S. polyacanthus, coxa I with tubercles and others with setae). Coxa IV dorso-lateral face with sparsely distributed granules, ventral face entirely granulated, with one long, oblique, bifid prodorsal apical apophysis (transversal in S. dilatatus, uniramous in S. funestus), dorsal branch longest and curved ventrad and ventral branch short and blunt; and one ventro-apical retro-lateral spine. Trochanters I–III granulate. Leg IV twisted retro-laterad from the trochanter, gradually untwisting along the femur (except S. funestus, straight). Trochanter IV longer than wide; prolateral face with one short, conical, blunt sub-basal apophysis, and one robust, blunt dorso-apical apophysis. Femora I–IV with granules roughly organized in six longitudinal rows (prodorsal, retro-dorsal, pro- and retro-lateral, proventral and retro-ventral rows); femora I and II unarmed. Femur IV curved, with marked inner curvature on the distal half (S. asperatus and S. ingens) or almost straight (S. dilatatus, S. funestus, and S. polyacanthus).

Tibiae I–III granulate, unarmed (except S. dilatatus and S. funestus, tibia III dorsal face granulate with retro-ventral row of tubercles increasing in size apically). Tibia IV dorsal face granulate, ventral face with tubercles sparsely distributed. Metatarsi I–IV minute granulate, unarmed. Tarsus III and IV each with ventral process, tarsal claws smooth. Penis. Ventral plate distal margin with slight (but conspicuous) to moderate concavity, two or three pairs of MS A, one pair of MS B or entirely absent, four or five pairs of MS C, one or two pairs of MS D, and one or two pairs of MS E. Glans sac tall, turgid, dorsally projected with antero-lateral projections, forming a sheath for the stylus. Glans without dorsal process; stylus inserted ventrally and smooth. Glans ventral process is short (half of stylus length), parallel to the stylus, apex curved ventrad, with a short semi-circular antero-lateral projection.

Geographic distribution

(Fig. 2). Central Chile, Región XIV Los Ríos; Metropolitan Region of Santiago; Región V Valparaíso; Región VIII Bio-Bío; Región IX Araucanía; and Region X Los Lagos. There are other localities mentioned in the literature besides the material studied here for S. polyacanthus in Neuquén (Argentina) and Magallanes, in the extreme south of Chile, however, we did not examine any material from there. The record of Sadocus funestus for Ecuador (Chimborazo, Riobamba) by Roewer (1913) is certainly a mislabeling because it does not agree with the known generic distribution (Cekalovic 1985; Kury 2003). Two species are widely distributed (S. asperatus and S. polyacanthus) and three others occur mainly in coastal mountains of Central Chile (S. funestus, S. dilatatus, and S. ingens).

Diagnosis

Sadocus asperatus resembles S. ingens, S. polyacanthus, and S. dilatatus by the bifid prodorsal apical apophysis on coxa IV. S. asperatus can be distinguished from the latter species by the combination of the following characters: lateral margin of dorsal scutum covered by granules; trochanter IV with a blunt retro-dorsal apical apophysis being half of the podomere length, and a rhombus retro-ventral apical tubercle; femur IV curved (in dorsal view), with a retro-lateral row of spiniform apophysis (the middle one longest).

Taxonomic notes

After examining the original description and the drawing of Gonyleptes bicornis, we concluded that it is of a male of S. asperatus. In the original description, the spines on the free tergite, the two apical apophyses on the trochanter IV and uneven spines in the inner part of the “leg” (referring to the femur IV) are mentioned. Those characters lead us to conclude that it is S. asperatus.

Note

The allotype MZSP 7874 was not used for the variation or in the distribution maps because it is a female, which lacks the diagnostic characters of the species (solely based on male characters).

Erratum

H. Soares (1968) incorrectly cited the collection number 7676 for the vial labelled: CHILE, Región de Biobío, Provincia Concepción, Quebrada Pinares, 4.XI.1964, T. Cekalovic coll., 1 ma. It is in fact 7876. The vial with number 7875 mentions 2 ma, when in fact, it includes 2 ma and 1 fe, and vial 7874 mentions only 1 ma, when it is in fact 1 fe.

Diagnosis

Sadocus polyacanthus resembles S. dilatatus by the posterior apophysis on the lateral margin of dorsal scutum, and femur IV almost straight. It is distinguished from the latter by the lack of a long, single retro-central apophysis (present in S. dilatatus) on femur IV, and by the presence of prolateral and retro-lateral rows of similar sized tubercles on femur IV and coxa IV being closer to the body (instead of spread to the sides as S. dilatatus).

Taxonomic notes

After examining the holotypes of S. conspicillatus, S. guttatus, and S. exceptionalis, we concluded that they were males within S. polyacanthus size variation. The apophyses size and shape on trochanter IV and the armature of femur IV (especially the retro-dorsal and retro-lateral row of spines size pattern) of all species are the same.

Species inquirendae

Sadocus allermayeri (Mello-Leitão, 1945)

Carampangue allermayeri Mello-Leitão, 1945: 158 [desc]; Soares and Soares 1954: 241 [cat]; Cekalovic 1968: 7 [cat]; 1985: 16 [cat] (type material MNRJ, 1 ma & 1 fe syntypes, destroyed, not examined).

Sadocus allermayeri: Kury, 2003: 191 [cat]; Kury et al. 2020b [cat].

Type locality

Chile. Región de Biobío. Concepción. Concepción.

Taxonomic notes

The type material, belonging to MNRJ, was lost in the fire that destroyed most of the arachnid collection (Kury, pers. comm.; Kury et al. 2018). The original description is poor for modern standards and it has no illustrations. However, the description allows to be diagnosed by: the presence of scutal area IV on dorsal scutum, coxa IV with one prodorsal apical bifid apophysis; trochanter IV with one retro-basal apophysis and three proapical apophyses. Sadocus asperatus, S. dilatatus, and S. ingens have the scutal area IV in dorsal scutum and coxa IV with a bifid prodorsal apical apophysis; but none of them has three apical apophyses on trochanter IV. The only species with four scutal areas on the dorsal scutum and trochanter IV with three apical apophyses is S. funestus, but the prodorsal apical apophysis on coxa IV is uniramous. Assuming that the description is correct, it implies that this is a valid species that we have not yet located among the material gathered for this revision of Sadocus.

Sadocus nigronotatus (Mello-Leitão, 1943)

Figure 8K

Carampangue nigronotatum Mello-Leitão, 1943: 8, fig 7 [desc]; Soares and Soares 1954: 242 [cat]; Cekalovic 1968: 7 [cat]: 1985: 17 [cat] (type material MNRJ, 1 fe holotype lost, not examined).

Sadocus nigronotatus: Kury, 2003, 191 [cat]; Kury et al. 2020b [cat].

Type locality

Chile. Provincia de Llanquihue. Región de Los Lagos. Maullín.

Taxonomic notes

The type material, belonging to the MNRJ, is lost (for the same reason as S. allermayeri). The original description is poor for modern standards, and both description and figure are based on a female. The females of the different Sadocus species are very similar and difficult to identify unequivocally. According to the original description, S. nigronotatus resembles S. polyacanthus in the presence of a spiniform apophysis on the lateral margin of the dorsal scutum, but can be distinguished by the presence of scutal area IV.

Taxonomic notes

We examined the type material of Sadocus brasiliensis and its external and penial morphology did not match that of other Chilean species of the genus. Based on its type locality, we examined other Brazilian Pachylinae genera and found striking similarities between S. brasiliensis and D. catharinensis. We examined detailed pictures of the type material kindly shared by Rafael N. Carvalho and additional material from the MZSP collection. Those species are the same, and we propose that S. brasiliensis is the junior synonym of D. catharinensis. Many Discocyrtus spp. have been transferred to revalidated genera or newly created subfamilies, such as Roeweriinae (Carvalho and Kury 2018) or Neopachylinae (Carvalho and Kury 2021). Indeed, the penial features of D. catharinensis (Fig. 15K, L) resembles those of that subfamily, which is corroborated in the present analysis: D. catharinensis is the sister species of R. bittencourti. Based on male genitalia and leg IV (see Carvalho and Kury 2018), D. catharinensis seems to belong to Discocyrtanus Roewer, 1929. However, because there is an ongoing study revising Discocyrtus conducted by Rafael N. Carvalho (MNRJ) and taking into account that it will have serious taxonomic consequences, we opted to propose only the synonymy of S. brasiliensis with D. catharinensis.

Gonyleptes horridus Kirby, 1819

Gonyleptes horridus Kirby, 1819: 452, pl. 22, fig 16 [desc]; Kury 2003: 128 [cat]; Hara et al. 2012: 38–39 [syst]; Pinto-da-Rocha et al. 2012: 26, 41–45 [syst]; Pinto-da-Rocha et al. 2014: 4, 17 [syst]; Hara 2016: 106–109 [syst]. (Type holotype NHM 1863.41, ma examined by detailed photographs).

Lycomedes calcar Roewer, 1913: 132, fig 59 [desc]; Acosta 1996: 218 [cit] (Type holotype SMF RI, 782, ma examined). syn. nov.

Lycomedicus calcar: Roewer, 1923: 444, fig 558 [rdesc]; Canals 1936: 69 [cat]; Soares and Soares 1954: 271 [cat]; Cekalovic 1968: 8 [cat], 1985: 18 [cat].

Sadocus calcar: Kury, 2003, 191 [cat]; Kury et al. 2020b [cat].

Taxonomic note

The holotype of Sadocus calcar is in a very bad state of preservation; only part of the carapace, with the ozopores, and leg IV remain. The rest of the prosoma and all of the other legs are absent. Even in this condition, we noted that S. calcar lacks the large tubercles and spines on the free tergites, which are diagnostic of Sadocus. Furthermore, the armature of trochanter IV and the long, bifid, C-shaped dorso-basal apophysis on femur IV are strikingly similar to those of Gonyleptes horridus, a common species in the state of Rio de Janeiro. Therefore, we propose S. calcar as a junior synonym of G. horridus. This synonymy made us conclude that the provenance of S. calcar is mistaken, because G. horridus is endemic to the Brazilian Atlantic rainforest. It is widely known that Roewer, unfortunately, indicated wrong provenance of a few species, and this seems to be the case for this species.

Eubalta planiceps (Gervais, 1842)

Remarks

Sadocus planiceps (originally Gonyleptes planiceps Gervais, 1842) has a convoluted taxonomic history, with many previously unknown synonyms detected, which will be published elsewhere (briefly commented in Pessoa-Silva et al. 2020). We excluded it from Sadocus because it lacks the synapomorphies of the genus. It also lacks the diagnostic characters of the genus, such as the typical ocularium shape and type of armature, dorsal scutum shape, just to name a few. Comparing with other species of Chilean Pachylinae, we detected striking similarities with Eubalta meridionalis. This synonymy did not go unnoticed by Kury et al. (2020a) in his catalogue, who also detected this in parallel with this revision. Finally, Kury et al. kindly invited us to publish this synonymy that resulted in a publication of that synonymy (Pessoa-Silva et al. 2020).
