Predation on Tropidurus hispidus (Squamata: Tropiduridae) by Lasiodora klugi (Aranea: Theraphosidae) in the semiarid caatinga region of northeastern Brazil Biota Neotropica
Vieira,Washington Luiz Silva; Gonçalves,Maria Betânia Ribeiro; Nóbrega,Rômulo Pantoja.
A predation event on Tropidurus hispidus (Tropiduridae) by the crab spider Lasiodora klugi (Theraphosidae) was observed in an arboreal caatinga area in northeastern Brazil. Arthropods are potential predators of small vertebrates and researchers have reported predation events involving spiders and herpetofauna in Neotropical regions. As such, the present short communication is the second case of predation of spiders on Tropidurus lizards in Brazil, and the first for the semiarid caatinga, reinforcing the argument that large spiders have relevant roles as predators of these animals.

Revision of the spider genus Pycnothele (Araneae, Nemesiidae) Iheringia, Sér. Zool.
Passanha,Victor; Indicatti,Rafael P.; Brescovit,Antonio D.; Lucas,Sylvia M..
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...

On the identity of the type species of Actinopus tarsalis (Araneae: Actinopodidae) Rev. Bras. Zool.
Miglio,Laura T.; Lucas,Sylvia M.; Bonaldo,Alexandre B..
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.

Tmesiphantes mirim sp. nov. (Araneae: Theraphosidae) from the Atlantic Forest of Bahia, Brazil, biogeographical notes and identification keys for species of the genus Rev. Bras. Zool.
Fabiano-da-Silva,Willian; Guadanucci,José Paulo Leite; DaSilva,Márcio Bernardino.
A new species of Tmesiphantes Simon, 1892 is described and illustrated, based on eight male specimens collected at the Una Biological Reserve, southern state of Bahia, Brazil. It is distinguished by the morphology of male palpal bulb and tibial apophysis. The new species is very small and is the smallest theraphosid described to date (body length 5.5 mm). It is distinguished from congeners by the size, which vary from 12 mm (T. riopretano) to 23.8 mm (T. nubilus) in other species of the genus, aspect of palpal bulb, sternal posterior sigillae close to sternal margin and by the aspect of tibial apophysis which lacks the prolateral branch. Tmesiphantes presently comprises nine species. Sixth have been described for the southern region of Bahia, a well known...

A new species of Masteria (Araneae: Dipluridae: Masteriinae) from southeastern Brazil Rev. Bras. Zool.
Pedroso,Denis Rafael; Baptista,Renner Luiz Cerqueira; Bertani,Rogério.
A new species of Masteria L. Koch, 1873 from iron ore caves at Caeté and Santa Bárbara, state of Minas Gerais, Brazil, Masteria emboaba sp. nov., is described. It was collected inside caves and in the litter of nearby dry forests. It is the first masteriine species described from southeastern Brazil and the second masteriine species for the country. The new species is the only known Masteria with only two eyes. Additionally, the male of M. emboaba sp. nov. has only two regular, thin spines at the apex of tibia I, lacking the tibial apophysis found in most other Masteria species. The only other described Masteria species that has spines in the place of tibial apophysis is M. aimeae (Alayón, 1995) from Cuba; however, the last species has a longer and sinuous...

Description of two new species of Lycinus (Araneae: Nemesiidae) Rev. Bras. Zool.
Lucas,Sylvia M.; Indicatti,Rafael P..
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...

A new species of Melloina (Araneae: Paratropididae) from Venezuela Rev. Bras. Zool.
Bertani,Rogério.
A new species of Melloina Brignoli, 1985, Melloina santuario sp. nov., is described from a cave in Venezuela. This is the third species described in this rarely sampled genus, and the first species known from both male and female. The male of M. santuario sp. nov. is distinguished by a longer embolus and fewer number of spines on the anterior tarsi. Females and immatures are distinguished by having fewer numbers of labial cuspules. The description of a new species from male and female samples increases our knowledge about Melloina. This added knowledge is important to the understanding of mygalomorph relationships, mainly in the Theraphosoidina, as Melloina is a basal genus within the Paratropididae.

Metriura Drolshagen & Bäckstam, 2009 (Araneae: Dipluridae) is a junior synonym of Fufius Simon, 1888 (Araneae: Cyrtaucheniidae) Rev. Bras. Zool.
Bertani,Rogério; Fukushima,Caroline Sayuri; Nagahama,Roberto Hiroaki.
The monotypic diplurid Metriura Drolshagen & Bäckstam, 2009 is placed in synonymy with Fufius (Cyrtaucheniidae) syn. nov. since Metriura lacks two of three diplurid synapomorphies (elongate posterior lateral spinnerets and the widely separated posterior median spinnerets) and shares synapomorphies with both aporoptychine cyrtaucheniids (subquadrate maxilla and a longer than wider labium) and Fufius (recurved and broad fovea, the typical incrassate tibia I of the male, with the spur having a single short branch and an apical megaspine, the basally curved metatarsus I and provided with a ventral tubercle). The type species of Metriura, M. striatipes Drolshagen & Bäckstam, 2009 is considered valid, and due to the synonymy of Metriura with...

Masteria manauara sp. nov., the first masteriine species from Brazil (Araneae: Dipluridae: Masteriinae) Rev. Bras. Zool.
Bertani,Rogério; Cruz,Wanessa Ribeiro; Oliveira,Maria Ermelinda do Espírito Santo.
A new species of Masteria L. Koch, 1873 from Manaus, Brazil, Masteria manauara sp. nov., is herein described. The specimens were collected by hand or using litter bags in the leaf litter around Attalea attaleoides (Barb. Rodr.) palm trees. The new species resembles Masteria colombiensis Raven, 1981 by lacking paraembolic apophysis on male copulatory organs and having spiniform apophysis on the ventral metatarsus I. It differs in the tibial spur, made of two subdistal, spiniform and converging spurs. Females are unique in having two spermathecae with slender helicoidal stalks. Males and females have only six eyes, and are tiny, even when compared with other Masteria species.

On the Brazilian Amazonian species of Acanthoscurria (Araneae: Theraphosidae) Rev. Bras. Zool.
Paula,Felipe dos S.; Gabriel,Ray; Indicatti,Rafael P.; Brescovit,Antonio D.; Lucas,Sylvia M..
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...

Litter dwelling mygalomorph spiders (Araneae: Microstigmatidae, Nemesiidae) from Araucaria forests in southern Brazil, with the description of five new species Zoologia
Indicatti,Rafael P.; Lucas,Sylvia M.; Ott,Ricardo; Brescovit,Antonio D..
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...
