Abstract

The praying mantis subgenus Syngalepsus Beier, 1954 occurs in sub-Saharan region and represents the least diverse subgenus of Galepsus in Africa (Ehrmann 2002). All species included within the subgenus Syngalepsus are comprehensively revised with a distribution stretching from North of Congo Basin to South Africa. Two new species of Galepsus (Syngalepsus) Beier, 1954 (Mantodea, Tarachodidae) from the Central African Republic (CAR) and Malawi are described. Among several Galepsus specimens collected during scientific expeditions of SANGHA, Biodiversité en Terre Pygmée, in CAR’s Dzanga-Ndoki National Park, a specimen differed by genitalia conformation and other morphological characters. Two specimens collected in Malawi proved to differ by genitalia morphology. Galepsus (Syngalepsus) bucheti sp. n. and Galepsus (Syngalepsus) dudleyi sp. n. are described. An identification key for the six species of the subgenus is provided.

Résumé

Les mantes du sous-genre Syngalepsus Beier, 1954 se rencontrent en région sub-saharienne et représentent le sous-genre le moins diversifié des Galepsus en Afrique (Ehrmann 2002). L’ensemble des espèces du sous-genre Syngalepsus sont révisées avec leur distribution s’étirant du nord du bassin du Congo à l’Afrique du Sud. Deux nouvelles espèces de Galepsus (Syngalepsus) Beier, 1954, provenant de République centrafricaine et du Malawi (Mantodea, Tarachodidae) sont décrites. Parmi les différents spécimens de Galepsus rapportés des missions scientifiques du programme SANGHA, Biodiversité en Terre Pygmée, situées au sein du Parc National Dzanga-Ndoki, un individu diffère des autres par la conformation de sa morphologie et ses genitalia. Durant des recherches au Muséum national d’Histoire naturelle, Paris, deux spécimens collectés au Malawi diffèrent par la morphologie de leurs genitalia. Galepsus (Syngalepsus) bucheti n. sp. et Galepsus (Syngalepsus) dudleyi n. sp. sont décrites. Une clé dichotomique est proposée pour l’identification des six espèces du sous-genre Syngalepsus maintenant connues.

Introduction

Subgenus Syngalepsus was erected by Max Beier in 1954 to organise some species from the genus Galepsus Stål, 1876: G. (S.) bipunctatus described in 1931 and G. (S.) denigratus Beier 1954. Beier also described G. (S.) birkenmeierae in 1969. Kaltenbach described a fourth species, G. (S.) beieri, from South Africa in 1996. In total, four species are currently known (Ehrmann 2002, Otte and Spearman 2005). All species of the subgenus have the vertex, straight or slightly arched, without bump or incision near the eyes and a right phallomere with the posterior apical region rounded and toothless, unlike Onychogalepsus. The prosternum has two circular black spots, more or less covered by a black patch. Three of the species are present in Southern Africa: South Africa (Natal) for G. (S.) beieri Kaltenbach (1996: 233); Mozambique and South Africa for G. (S.) bipunctatus Beier (1931: 3) (Type species) and Malawi for G. (S.) birkenmeierae Beier (1969b: 201). The fourth species, G. (S.) denigratus Beier (1954: 19), was collected in Angola (Beier 1969a), Gabon, Republic of Congo, Democratic Republic of Congo and Uganda (Beier 1957, Roy 1968).

The discovery of a specimen in CAR that seems close to Syngalepsus led me to gather all the existing information concerning this subgenus (Moulin et al. 2017). The old descriptions have been revised and the figures of the genitalia grouped. Examination of its morphology and that of other specimens preserved in the collection has highlighted a second new species, native to Malawi. This paper aims to provide additional knowledge about Mantodea from Africa. Here we provide details about morphology and distribution of known species of the subgenus Syngalepsus and describe two new species.

Taxonomy

After the examination of several specimens of Galepsus genus in the Muséum national d’Histoire naturelle, Paris (MNHN) and a bibliographic survey (Beier 1931, 1954, 1957, 1969a, 1969b; Roy 1968; Kaltenbach 1996, 1998; Ehrmann 2002; Otte and Spearman 2005), the genus Galepsus (Syngalepsus) appears to include six species. Two of these are unknown and are described in this subgenus revision. The genitalia were illustrated from types for all existing species, which served as the central distinguishing feature for the treated species.

Materials and methods

During the scientific expedition named “SANGHA, Biodiversité en terre Pygmée” (2012) in CAR, some Galepsus individuals were collected. Two species were identified: G. (Galepsus) globiceps Beier, 1942 and G. (Galepsus) laticeps Werner, 1907. But one specimen was atypical of the others and its genital characters were similar to those of Syngalepsus. In my comparisons to collection specimens, two undetermined specimens from Malawy were found in the material of the Muséum national d’Histoire naturelle, Paris, France. The specimens exhibit the diagnostic characters of the subgenus Syngalepsus (sensu Beier 1954) and differ from the RCA specimen and the four known species.

The specimens were photographed with a Dynax 5D Konica Minolta camera and a Leica MC 120 HD camera mounted on a S8APO Leica stereomicroscope. The freeware Combine ZP (Hadley 2008) was used to process images.

Taxonomy relied on Mantodea Species File website (Otte et al. 2018) as well as recent works on praying mantis molecular phylogenetics (Svenson and Whiting 2009, Wieland 2013, Roy 2014, Svenson et al. 2015). All morphological descriptions and measurements (in millimeters) refer to the material studied here unless explicitly stated otherwise. Terminology follows Brannoch et al. (2017) and Shcherbakov (2017). A total of 12 measurement classes were captured including:

1 Body length = length of body from central ocelli to posterior tip of wing or abdomen (intraspecifically variable measurement, primarily for general size estimation).

2 Forewing length = from proximal margin of axillary sclerites to distal tip of the discoidal region.

3 Pronotum length = from anterior margin to posterior margin.

4 Pronotum width = from lateral margins at the widest point, the supra-coxal bulge.

5 Head width = from lateral margins of the eyes at widest point.

6 Prothoracic coxae length = from proximal margin abutting pronotum to trochanter.

7 Prothoracic femur length = from proximal margin abutting trochanter to distal margin of genicular lobe.

8 Prothoracic tibiae length = from distal margin of genicular lobe to distal terminal spur.

9 Prothoracic femur width = at the widest point.

10 Anteroventral femoral spine count = all inner marginal ridge spines but excluding the genicular spine.

11 Anteroventral tibial spine count = all inner marginal ridge spines but excluding the distal terminal spur.

12 Posteroventral tibial spine count = all outer marginal ridge spines but excluding the distal terminal spur.

As part of the revision of Syngalepsus, the descriptions of the four known species are repeated here, according to the original texts, translated into English. The questioning of the identity of the female allotype referred to G. (S.) denigratus by Beier between 1957 and 1969 is re-evaluated here with the examination of two females, conserved at the MNHN, from the Republic of the Congo. The genitalia illustrated in the original documents are reproduced here (Figs 1, 2).

Additional description of Galepsus (Syngalepsus) denigratus by Beier (1957: 141)

“Zur Beschreibung des männlichen Kopulationsorgans ist folgendes nachzutragen: Der linke Epiphallus hat dorsal einen oralwärts gerichteten scheibenförmigen Anhang, medial einen stumpfen Haken; sein Basalsklerit ist kurz; der Phallus ist kurz, pfriemenförmig, mit relativ grossem Basalack; der Hypophallus hat einen derben, kahnförmigen Lateralteil und einen häutigen Lobus. Das Endglied der Cerci ist in der Regel lang und schmal. – Körper L. ♀ 26–30 mm; Kopf B. 2,9–3,1 mm; Pronotum L. 6,9–7 mm, B. 2,2 mm; Elytren L. 17,5–19,5 mm. Das Weibchen dieser Art, das in einem Stück (Allotype) von Kasai, Shamba, vorliegt, war noch unbekannt. Es ist dorsal fast einheitlich braun gefärbt, nur der Scheitelbogen ist geschwärzt und die Metazone des Pronotums trägt zwei grosse schwarze Flecke. Dorsalrand des etwas queren Frontalschildes fast gerade. Scheitel flach gewölbt. Elytren schwärzlich-rötlichbraun, ventral entlang dem R geschwärzt. Alae grösstenteils schwärzlich, mit rötlichbraunen Rändern. Prosternum wie beim Männchen. Vordercoxen präapikal mit schwärzlicher Querbinde. Trochanter medial grösstenteils schwarz. Femur medial in der Ventralhälfte Schwarz, mit schwarzen Dornen. Vordertibien medial bräunlich, die Tarsenglieder geschwärzt. Fang- und Schreitbeine lateral bezw, dorsal braun punktiert. Supraanalplatte breit dreieckig, gekielt. – Körper L. 27 mm; Kopf B. 3,3 mm; Pronotum L. 7 mm, B. 2,7 mm; Elytren L. 4 mm. – Es ist in der Färbung dem Weibchen von femoratus G.-Tos aus dem Betschuanaland sehr ähnlich, unterscheidet sich aber von diesem durch helle Vordertibien und die Körpermasse, vor allem durch schlankeres Pronotum und relative kürzere Elytren.”

“To describe the male genitalia, the following is to be added: The left phallomere has a dorsally directed disc-shaped appendage (L4B), medially a blunt hook; sclerite L4A is short; the posterior process of phalloid apophysis (apa) is short, belt-shaped, with a relatively large basal coat; ventral phallomere has a rough, posterior lateral part and a membranous lobe. Distal cercomere are usually long and narrow. – Body length ♀ 26–30 mm; width of head 2,9–3,1 mm; pronotum length 6,9–7 mm; width of pronotum 2,2 mm; forewing length 17,5–19,5 mm.

The female of this species, of which there is one specimen (allotype) collected at Kasai, Shamba, was previously unknown. It is dorsally almost uniformly brown, only the vertex is blackened and metazone carries two large black spots. Dorsal margin transverse, lower frons almost straight. Vertex flat arched. Forewings blackish-reddish brown, blackened ventrally along anterior radius. Hindwings mostly blackish, with reddish brown edges. Prosternum as in the male. Forecoxae with blackish pre-apical bandage. Trochanter mostly black. Forefemora half black in ventral face, with black thorns. Fore tibiae half brownish, tarsus blackened. Meso- and metathoracic legs lateral and dorsal brown dotted. Supra-anal plate wide, triangular and keeled. – Body length 27 mm; width of head 3,3 mm; pronotum length 7 mm; width of pronotum 2,7 mm; forewings length 4 mm. It is very similar in colour to the female of Galepsus (Onychogalepsus) femoratus Giglio-Tos collected from Bechuana land (Botswana), but differs from it in terms of its bright fore tibiae and body mass, above all by a slimmer pronotum and relatively shorter forewings.”

The female symbol in the description of Beier, in 1957, is a mistake. He wanted to indicate the measurements for the males.

Additional description of Galepsus (Syngalepsus) denigratus by Beier (1969a: 21)

“Das von mir seinerzeit (1957) für das Weibchen von denigratus gehaltene Exemplar gehört offensichtlich nicht dieser Art an. Es liegen nun 4 Weibchen vor, die ich mit Bestimmtheit dieser Art zuzählen möchte. Sie lassen sich folgendermassen charakterisieren: Weibchen. Ober- und Unterseite einschliesslich der kurzen Elytren braun, der Scheitel in Längsstreifen schwach angedunkelt, Occiput bisweilen mit einem schwarzen Punkt; Pronotum mit zwei Paaren kleiner brauner Punkte in der vorderen Hälfte der Metazone, Prosternum wie beim Männchen, meist jedoch etwas breiter geschwärzt; Vordercoxen medial mit zwei schwarzen Apikalmakeln, Trochanter mit schwarzer Medialmakel, Vorderfemora medial vor und hinter der Krallenfurche mit einer grösseren schwarzen Makel, weiter distal mit einigen braunen Punktmakeln, an der Basis der hellen grossen Innendornen ebenfalls mit je einer braunen Punktmakel; Beine braun gesprenkelt. Seiten des Pronotums äusserst fein körnchenförmig gezähnelt. – Körper-L. 32–34 mm; Kopf-B. 3,8–4 mm; Pronotum-L. 7,5–8 mm, B. 2,9–3,1 mm; Elytren-L. 4,5–5 mm; Hinterfemora 6–6,5 mm. – Die Weibchen sind an der charakteristischen Fleckung der Voderbeine leicht kenntlich. Die Art ist neu für Angola. Sie war bisher nur aus dem Congo bekannt.”

“The specimen I held at that time (1957) of the female denigratus obviously does not belong to this species. There are now 4 females that I want to count with certainty of this kind. They can be characterised as follows: Female. The upper and lower side including stigma of forewings, brown, the apex of the head dimly darkened in longitudinal stripes, gena sometimes with a black dot; pronotum with two pairs of small brown dots in the anterior half of the metazone, prosternum as in the male, but usually a little more blackened; fore coxae with two apical black spots, trochanter with a medial black spot, forefemora with a, medial and behind the claw furrow, larger blackish spot, further distal with a little brown spot, at the base of the larger anteroventral femoral spines also each with a brown spot; Legs speckled brown. Margins of pronotum extremely fine granulated serrated. – Body length 32–34 mm; width of head 3,8–4 mm; pronotum length 7,5–8 mm; width of pronotum 2,9–3,1 mm; forewings length 4,5–5 mm; metathoracic femora length 6–6,5 mm. – The females are easily recognizable by the characteristic patch on the forelegs.

The species is new to Angola. It was previously known only from the Congo.”

Note: The female described in 1957 from Shamba in Kasai (Republic of the Congo) is confirmed to be G. (S.) denigratus, after examination.

Holotype

Male deposited in ZMAN Amsterdam. Type locality: Lake St. Lucia, False Bay, Natal, South Africa. Paratype: Male deposited in NHM Wien.

Material examined

1 male. South Africa, Mpumalanga, Blyde River Canyon, Swadini Resort, 24°30'54.7"S, 30°48'8.64"E, 600 m, 18.XI.2017 (SA17-05 field code), Decaëns T. & Rougerie R. leg., genitalia prep. Moulin NM200 (RCNM).

Diagnosis

Galepsus (S.) beieri is very similar to Galepsus (S.) bipunctatus and G. (S.) birkenmeirae. G. (S.) beieri is distinguished from G. (S.) birkenmeirae and G. (S.) denigratus by the presence of two black spots on prosternum. Kaltenbach, in 1996, speaks of not blackened pronotum in ‘Differentialdiagnose’ but he confuses with the prosternum. Right phallomere with a process on the main posterior lobe; ventral plate (pia) with a tooth turned to the right at the apex; Left phallomere with posterior process of phalloid apophysis (apa) (pseudophallus) ended with rounded apex, distal process (paa) (titillator) with apex in mallet form at the apex, covered by thick bristles.

Discussion

The present study led to the description of two new species, Galepsus (Syngalepsus) bucheti sp. n. and Galepus (Syngalepsus) dudleyi sp. n. Males are easily identifiable using the characters of both habitus and male genitalia. However, females are unknown, which is common for mantises because studies with light trap sampling fail to attract females. Here, only females of G. (S.) denigratus are known (Beier 1969a). They are brachypterous and likely live on tree trunks and branches. Sweep nets and visual searching should be used more broadly in Mantodea studies to ensure more females can be collected. Furthermore, this method will also reveal mantises’ micro-habitat preferences. In CAR, no female of G. (S.) bucheti sp. n. were collected, although all known modern sampling techniques were implemented (sweeping, beating, tree climbing, light trap). With brachypterous females it a likely the distribution of each species could be restricted to small geographic ranges, which could indicate many species remain to be discovered in remote areas of Africa and other parts of the world.
