Homoeomma simoni and Plesiopelma flavohirtum are transferred to Catanduba and five new species are de-scribed: C. tuskae, C. araguaia, C. piauiensis, C. canabrava and C. peruacu. The species occur mainly in central Brazil,in Cerrado areas, with some species also occurring in Atlantic forest (C. tuskae sp. n. ) and Caatinga (C. piauiensis sp. n. and C. peruacu sp. n.).

(1971) 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 (1985) 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 (1995) 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.

The male of Tityus serrulatus Lutz & Mello, 1922 is redescribed. New diagnostic characters are given for T. kuryi Lourenço 1997, T. melici Lourenço 2003, T. serrulatus and T. stigmurus Thorell, 1876. Tityus lamottei Lourenço 1981 and T. acutidens Mello-Leitão, 1933 are considered a junior synonyms of T. serrulatus (syn. nov.). The female of Tityus kuryi and the male of Tityus stigmurus are also redescribed. New distribution records are presented for species included in the complex.

Research paper thumbnail of Litter dwelling mygalomorph spiders (Araneae: Microstigmatidae, Nemesiidae) from Araucaria forests in southern Brazil, with the description of five new species

Five of those species, five are new. Microstigmatidae: Xenonemesia araucaria sp. nov., males differ from those of X. platensis Goloboff, 1988 and X. otti Indicatti, Lucas & Brescovit, 2007 by the curved and very long embolus in the male palp. Females differ from the remaining species of the genus in the seminal receptacle very long and sinuous or twisted. Nemesiidae: Acanthogonatus ericae sp. nov. - males resemble those of A. tacuariensis (Pérez-Miles & Capocasale, 1982) and A. quilocura Goloboff, 1995 by the serrated, curved and long embolus but are distinguished by the presence of a flange on the apex of the embolus. Females differ from the remaining Acanthogonatus by the short copulatory ducts, arising from the apex of the basal dome. Stenoterommata arnolisei sp. nov. is distinguished fr...

Bumba have been characterized by the type IV urticating setae present, retrolateral process on male palpal tibia, palpal bulb resting in a ventral distal excavation of palpal tibia, metatarsus I passes between the two branches of tibial apophysis when flexed, presence of spiniform setae on prolateral and retrolateral sides of maxillae and coxae I-IV. In this paper we include the row of teeth (denticulate row) in the median region of the inferior prolateral keel in all male palps. This structure range from a residual tooth to a ridge of up to five teeth. Both, the denticulate row and the retrolateral process on male palpal tibia in males could be considered as putative synapomorphies for Bumba. Here, Homoeomma humile Vellard, 1924 is transferred to Bumba and redescribed, while the female is described for the first time. Bumba cabocla (Pérez-Miles, 2000) is synonymyz...
