A revision of Neodiplothele (Araneae: Mygalomorphae: Barychelidae)

Abstract

The Neotropical Sasoninae Neodiplothele Mello-Leitão, 1917 is revised and now includes eight species. Neodiplothele can be distinguished from other Sasoninae by the absence of the posterior median spinnerets and differs Neotropical relatives as Cosmopelma by the absence of cuspules on coxae of leg I and Paracenobiopelma by the absence of cuspules on the labium. The male of N. irregularis Mello-Leitão, 1917 and N. picta Vellard, 1924 are described and illustrated for the first time. Neodiplothele leonardosi Mello-Leitão, 1939 is considered a junior synonym of N. irregularis. Five new species are described from Brazil: N. aureus sp. nov. from the states of Ceará, Rio Grande do Norte, Paraíba, and Minas Gerais, N. itabaiana sp. nov. from Sergipe, N. martinsi sp. nov. from Bahia, Espírito Santo, and Minas Gerais, N. indicattii sp. nov. from Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo, N. caucaia sp. nov. from Ceará, Goiás, and Mato Grosso do Sul. Two informal groups are proposed based on genitalia morphology: irregularis group and picta group. An identification key and new distribution records for all known species are given.

Natural history; Neotropical region; Sasoninae; taxonomy; trapdoor spider


Barychelidae Simon, 1889 is subdivided in two subfamilies: Barychelinae and Sasoninae (Raven 1985Raven RJ (1985) The spider infraorder Mygalomorphae (Araneae): cladistics and systematic. Bulletin American Museum of Natural History 182: 1-180.) which includes 42 genera and 291 species (World Spider Catalog 2015World Spider Catalog (2015) World spider catalog. Bern, Natural History Museum Bern, version 15.5, available online at: http://wsc.nmbe.ch [Accessed: 4/4/2015]

). Sasoninae currently includes the genera: Sason Simon, 1887, Cosmopelma Simon, 1889, Neodiplothele Mello-Leitão, 1917 and Paracenobiopelma Feio, 1952, from these genera, only Sason is not present in the Neotropical region (Raven 1985Raven RJ (1985) The spider infraorder Mygalomorphae (Araneae): cladistics and systematic. Bulletin American Museum of Natural History 182: 1-180., Goloboff 1995Goloboff PA (1995) A revision of the South American spiders of the family Nemesiidae (Araneae, Mygalomorphae). Part I: species from Peru, Chile, Argentina, and Uruguay. Bulletin American Museum of Natural History 224: 1-189.). Sasoninae differs from Barychelinae by the presence of a narrow clypeus, short and conical apical segment of the posterior lateral spinnerets, labium and eye tubercle wider than long (Raven 1985Raven RJ (1985) The spider infraorder Mygalomorphae (Araneae): cladistics and systematic.

Journal of Arachnology 14: 47-70.).

Neodiplothele was established by Mello-Leitão (1917Mello-Leitão CF (1917) Notas arachnologicas. 5 espécies novas ou pouco conhecidas do Brazil. Broteria 15: 74-102.) based on N. irregularis, a female from Campina Grande, Paraíba, Brazil. Later, another three species from Brazil were described: N. fluminensis Mello-Leitão, 1924 based on a male from Floresta da Tijuca, N. picta Vellard, 1924 based on a female from Niterói, both from state of Rio de Janeiro and N. leonardosi Mello-Leitão, 1939 based on a female from Cabeceira do Paraguaçu, state of Bahia.

Bücherl et al. (1971Bücherl WA, Timotheo da Costa A, Lucas SM (1971) Revisão de alguns tipos de aranhas caranguejeiras (Orthognatha) estabelecidos por Candido de Mello-Leitão e depositados no Museu Nacional do Rio de Janeiro. Memórias do Instituto Butantan 35: 117-138.) redescribed N. fluminensis, presented an illustration of the male palpal bulb for the first time and observed that N. leonardosi was a juvenile specimen. Raven (1985Raven RJ (1985) The spider infraorder Mygalomorphae (Araneae): cladistics and systematic. Bulletin American Museum of Natural History 182: 1-180.) transferred Neodiplothele to Pycnothelinae (Nemesiidae) due to the presence of numerous keels on the bulb, small intercheliceral tumescence, absence of third tarsal claw and pseudosegmented tarsi of males. This transfer was rejected by Goloboff (1995Goloboff PA (1995) A revision of the South American spiders of the family Nemesiidae (Araneae, Mygalomorphae). Part I: species from Peru, Chile, Argentina, and Uruguay. Bulletin American Museum of Natural History 224: 1-189.) who classified the genus back in Barychelidae, due to the well-developed claw tufts and tarsal claws without teeth, and included the genus in Sasoninae for sharing with Cosmopelma and Paracenobiopelma the presence of an intercheliceral tumescence and the bulb with low ridges. Examination of the type-material and a large number of specimens from several Brazilian collections have offered us the opportunity to revise the genus, describe the male of N. irregularis and N. picta for the first time, and also describe five new species, all from Brazil. Two informal groups of species are proposed based in genitals characters: irregularis group and picta group.

MATERIAL AND METHODS

The material examined is deposited in the following collections: Instituto Butantan, São Paulo (IBSP, A.D. Brescovit); Museu Nacional, Rio de Janeiro (MNRJ, A.B. Kury); Museu de Zoologia, Universidade de São Paulo, São Paulo (MZSP, R. Pinto da Rocha); Universidade Federal de Minas Gerais, Belo Horizonte (UFMG, A.J. Santos) and Universidade Federal do Piauí, Floriano (CHNUFPI, L.S. Carvalho). All measurements are in millimeters. Total body length includes carapace and abdomen without chelicerae and spinnerets. Length and width of carapace, eye tubercle, labium and sternum are measures of maximum values obtained. The length measurement of leg segments was obtained between joints in dorsal view. Termino logy for number and disposition of spines follows that of Petrunkevitch (1925Petrunkevitch A (1925) Arachnida from Panama. Transactions of the Connecticut Academy of Arts and Sciences 27: 51-248.) with modifications proposed by Bertani (2001Bertani R (2001) Revision Cladistic analysis and zoogeography of Vitalius, Nhandu, and Proshapalopus; wtih notes on other theraphoside genera (Araneae, Theraphosidae). Arquivos de Zoologia 36: 265-356.). Digital multi-focal photos were taken with a Leica DFC500 digital camera attached to a Leica MZ16A stereoscopic microscope. Extended focal range images were composed with Leica Application Suite version 2.5.0. SEM. These images were taken in the Scanning Electron Microscope FEI Quanta 250 in the Laboratório de Biologia Celular of Instituto Butantan. Spermathecae were dissected and submitted to digestion by Ultrazyme(r) Enzymatic Cleaner for 24 hours in order to observe of the internal structure. The structures of internal genitalia of females were illustrated in dorsal view. Male palpal bulb from the left side was removed from the cymbium and illustrated. The geographic coordinates were obtained using Google Earth and the distribution maps were made using the program DIVA-GIS 7.5.

Type species. Neodiplothele irregularis Mello-Leitão, 1917.

Diagnosis. Species of the genus Neodiplothele can be distinguished from the others Neotropical Sasoninae genera by the absence of the posterior median spinnerets (PMS). Neodiplothele resembles Cosmopelma and Paracenobiopelma by the apical segment of the posterior lateral spinnerets conical, labium and eye tubercle wider than long, however differs from Cosmopelma by the absence of cuspules on coxae of leg I and from Paracenobiopelma by the absence of cuspules on labium.

Description. Total length of males: 5.55-12.3 and females 7.76-16.75. Clypeus about as wide as long; eye tubercle raised, well defined. Anterior row of eyes procurved, posterior row slightly recurved (Fig. 1). Thoracic furrow small and slightly procurved. Labium wider than long, without cuspules. Rastellum formed by 6-25 short conical spines on promargin (Fig. 2). Intercheliceral tumescence in males, small, soft, pallid with few setae; maxillae rectangular, anterior lobe not well defined with 3-14 cuspules on inner corner. Plumose clavate trichobothria in two rows on the cymbium of the male palp and tarsus I of the female (Figs. 7-8). Trichobothria with conspicuous groove and filiform trachoma, distributed in two parallel rows in all metatarsi (Fig. 9). Tarsal organ elevated without longitudinal ridge originating from proximal end and with a very small receptor (Fig. 4). Tarsi I-IV of males pseudo segmented.

Tibia I of males unmodified (Figs. 23-24), except in N. fluminensis, N. itabaiana sp. nov. and N. martinsi sp. nov. with megaspine (Figs. 31-32, 47-48, 57-58). Male palpal bulb with pyriform aspect in irregularis group (Figs. 18-21, 27-30, 35-38, 43-46, 53-56) or globose aspect in picta group (Figs. 68-71, 76-79, 87-90). Set of ventral keels marked near the embolus, not so well marked in N. fluminensis (Figs. 27-30) and N. picta (Figs. 68-71), and inconspicuous in N. caucaia sp. nov. (Figs. 87-90). Straighter embolus with a curve on the apical portion or with a strong sinuosity in irregularis group. Embolus long and very thin in picta group; with a slight curvature on the median region in N. indicattii sp. nov. (Figs. 76-79) or with a strong curvature (Figs. 68-71, 87-90). Female seminal receptacle with two branches emerging from a base. Large base in picta group (Figs. 73, 81) or narrowed in irregularis group (Figs. 25, 40, 50-51, 60-61). The internal branch with median sclerotization; sometimes strongly spiraled (Figs. 40, 73, 81) or slightly sinuous (Figs. 25, 50-51, 60-61). External branch straight without sinuosity, except in N. indicattii sp. nov. (Fig. 81). Duct of the external branch with median constriction in irregularis group. Lobes of the internal branch globose (Figs. 60-61) or filiform (Figs. 25, 50-51, 73). Posterior median spinnerets absent; apical segment of PLS very short with several spigots (Fig. 3).

Synonymy. Neodiplothele leonardosi is based on a juvenile specimen and is considered as junior synonym of N. irregularis, confirmed by the examination of several juveniles of the N. irregularis from the areas near the type locality and the color pattern.

Diagnosis. Males of Neodiplothele irregularis can be distinguished from the other species of the group by the absence of megaspine on the tibia I (Figs. 22-23). Females are distinguished from the remaining species by the seminal receptacles with an uncoiled internal branch (Fig. 25).

Distribution. Brazil: states of Bahia, Espírito Santo and Minas Gerais (Fig. 92).

Etymology. The species is in honor of Pedro Henrique Martins, the collector of this species.

Variation. Males (n = 6) total length 5.7-7.5; carapace 2.88-3.96 long, 2.4-3.3 wide; femur I 2.64-3.48. Females (n = 4) total length 8.64-9.6; carapace 4.2-4.62 long, 3.3-3.86 wide; femur I 3-3.16.

Natural history. The species were collected in a small ravine of sandy soil located on the edge of a road (Fig. 64, arrow). The tubular burrow was covered by silk and protected by a malleable trapdoor very well camouflaged with debris and mosses (Figs. 65-66). The burrow had a circular shape with only one entrance. It was about 2-3 cm wide and 10-12 cm deep. Several exuviae were found next to the burrows and base of the ravine.

The picta group

This group is characterized by the globose aspect of the palpal bulb with a very long and thin embolus with a curvature on the median region (Figs. 68-71, 76-79, 87-90). Female seminal receptacle with narrow base (Figs. 73, 81). Three species are included: Neodiplothele picta, N. indicattii sp. nov. and N. caucaia sp. nov.

Diagnosis. Neodiplothele picta can be easily recognized by the color pattern of the dorsal area of the abdomen with light distinct spots (Figs. 67, 72, 74). Males of N. picta can be distinguished by the strong curvature on the median half of the embolus with slender keels (Figs. 13, 68-71). Females can be distinguished by the aspect of the seminal receptacle with the external branch without sinuosity (Fig. 73).

Distribution. Brazil: states of Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo (Fig. 76).

Etymology. The species is in honor of the arachnologist Rafael Prezzi Indicatti, the collector of this species.

Variation. Males (n = 5) total length 4.16-8.16; carapace 2.24-4.56 long, 2.08-4.2 wide; femur I 2.24-4.25. Females (n = 6) total length 13.13-15.4; carapace 5.7-7.38 long, 5.1-7.12 wide; femur I 3.6-4.5.

Natural history. These specimens were collected manually in the Atlantic Forest (Parque Nacional da Serra dos Órgãos, Teresópolis, Rio de Janeiro and Parque Nacional do Itatiaia, Itamonte, Minas Gerais) at high altitudes (between 1000-2000 m). They build their burrows near the trees, roots and fallen trunks in ravines covered with vegetation. The ravines are on the trails edge and are about one meter above the ground level, as well as in N. martinsi sp. nov. The burrow has a canoe shape with two trapdoors camouflaged with mosses and each trapdoor is 2 cm wide (Figs. 84-85). Females were found at night, lurking in their burrows waiting for their prey with their legs out of the trapdoor (Fig. 85), and the male was found walking on the ground on the tracks edges at night.
