| The genus Pycnothele Chamberlin, 1917 is revised. The Brazilian species Pycnothele perdita Chamberlin, 1917, P. singularis (Mello-Leitão, 1934) and P. auronitens (Keyserling, 1891) are redescribed, diagnosed and illustrated. The females of P. auronitens and P. singularis are described for the first time and P. auripila (Mello-Leitão, 1946) from Uruguay, currently a junior synonym of P. auronitens, is revalidated. Pycnothele piracicabensis (Piza, 1938) is transferred to Rachias Simon, 1892, with which it shares the morphology of the sexual structures, restoring the original combination. Five new species are proposed for Brazil: Pycnothele rubra sp. nov., P. jatai sp. nov. and P. araraquara sp. nov., from state of São Paulo, P. arapongas sp. nov., from state... |

| A new species of Tmesiphantes Simon, 1892, T. aridai sp. nov., is described and illustrated based on three males and three females collected at the Floresta Nacional do Tapajós, Santarém, state of Pará, Brazil. Males can be distinguished from T. perp Guadanucci & Silva, 2012 by the palpal bulb with an inconspicous tegular basal projection, but presenting a very slender embolus with shorter keels not extending to the tip, and from T. nubilus Simon, 1892 by the tibial apophysis with two similarly sized branches, the prolateral one with a strong spine on the retrolateral margin. Females resemble T. nubilus by the aspect of the seminal receptacle but the constriction near the apex is less evident and apex shape is irregular. The new species represents... |

| The type species of the Neotropical Actinopus, A. tarsalis Perty, 1833, is redescribed based on material from the type locality, the state of Piauí, Brazil. The species appears to be restricted to northeastern Brazil and is newly recorded from the state of Sergipe. An old record from the state of Rio Grande do Sul is rejected. Actinopus tarsalis differs from other species of the genus by details of the male copulatory bulb: tegular apophysis absent, robust embolar base, inserted basally at a right angle (90°); embolar apices apex flattened and expanded, arrow-shaped in dorsal view. |

| Two new species of Lycinus Thorell, 1894 are described in this paper, L. portoseguro sp. nov. and L. choros sp. nov. Lycinus portoseguro sp. nov. is based on male and female from Porto Seguro, state of Bahia, Northeastern Brazil. This is the first record of a species of Lycinus from Brazil. Males of L. portoseguro sp. nov. differ from the remaining species of the genus by the presence of a retrolateral megaspine on tibia I and by the short embolus. Females can be distinguished by the scopulae divided on tarsi II. Lycinus choros sp. nov. is based on one male from La Serena, IV Region (Coquimbo), Chile. It is the eighth species described from this country. L. choros sp. nov. resembles L. epipiptus (Zapfe, 1963) by the longer embolus and differs from it by... |

| ABSTRACT The taxonomic history of Bumba Pérez-Miles, Bonaldo & Miglio, 2014 is mainly based on the inclusion of the new species. 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... |

| In this study the Brazilian Amazonian species of Acanthoscurria Ausserer, 1871 are redescribed: A. geniculata (C.L. Koch, 1841), A. tarda Pocock, 1903, A. juruenicola Mello-Leitão, 1923, A. theraphosoides (Doleschall, 1871). Acanthoscurria simoensi Vol, 2000 and A. insubtilis Simon, 1892, previously known from French Guyana and Bolivia, respectively, are recorded for Brazil by the first time. The females of these two species are described for the first time and a new species, A. belterrensis sp. nov., is described from Belterra, Pará, Brazil. In addition, four synonymies are established: A. transamazonica Piza, 1972 as junior synonym of A. geniculata; A. ferina Simon, 1892 and A. brocklehursti F.O.P.-Cambridge, 1896 of A. theraphosoides; and A. xinguensis... |

| 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... |

| The male of Acanthoscurria paulensis Mello-Leitão, 1923 is redescribed and the female is described for the first time. The male holotype, from Pirassununga, state of São Paulo, Brazil, could not be located and the redescription is based on specimens collected in the type locality. Acanthoscurria atrox Vellard, 1924 is considered a junior synonym of A. paulensis based on their original descriptions and figures of the male palpal bulb, and also supported by the study of several specimens from both type localities, Pirassununga and Campo Grande, state of Mato Grosso do Sul, Brazil. Acanthoscurria guaxupe Piza, 1972 is also considered a junior synonym of A. paulensis based on examination of the holotype. Acanthoscurria paulensis resembles A. chacoana Brèthes,... |

| Two new Nemesiidae species from Reserva Biológica do Tinguá, Rio de Janeiro, Brazil are described. Acanthogonatus minimussp. nov. differs from the remaining species of the genus by the male palpal bulb, which has very long and twisted embolus, ca. 2/3 the length of the palpal tibia, long and twisted spermathecae, anterior eye row recurved and fovea T-shaped. Chaco tinguasp. nov. differs from the remaining species of the genus by the retrolateral megaspine on tibia I, palpal embolus tip hook-shaped, inferior tarsal claw on all legs, absence of pubescence on the carapace and legs. Both species were collected with Winkler extractors in leaf litter. They are the smallest specimens in their respective genera and also among the world Nemesiidae described to... |

| The original description of this species was based on a single female and no illustrations of reproductive organs were presented. After we collected several specimens identified as I. seladonium, we decided to redescribe this species and discovered that the male, previously described as belonging to this species, was misidentified by MELLO LEITÃO (1923). Thus, in this paper the male of I. seladonium is newly described and the reproductive organs of male and female are described and illustrated in detail. Notes on the behavior and natural history of I. seladonium are presented based on the observation of live specimens in the field and in captivity. An immature of I. seladonium was observed constructing a hinged retreat with silk and little pieces of bark,... |

| Six mygalomorph spiders species belonging to two families, were collected in the Centro de Pesquisa e Conservação da Natureza Pró-Mata, São Francisco de Paula, state of Rio Grande do Sul, Brazil. 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... |

| Prorachias Mello-Leitão, 1924 é conhecido apenas pela espécie-tipo P. bristowei Mello-Leitão, 1924, descrita com base em uma fêmea do estado do Rio de Janeiro, Brasil. A descrição é sumária e incompleta, sendo omitidos caracteres importantes como o formato da espermateca. O exemplar-tipo, que deveria estar depositado no Museu Nacional do Rio de Janeiro, não foi localizado e está provavelmente perdido. O estudo de material coletado pelo Projeto "Biodiversidade de Arachnida e Myriapoda do Estado de São Paulo" e de material depositado na coleção do Instituto Butantan permitiu complementar a diagnose do gênero, redescrever a fêmea e descrever pela primeira vez o macho desta espécie. Além disto, dados sobre biologia são apresentados e a distribuição geográfica... |
