1. Description and molecular characterization of a new species of tarantula, Pamphobeteus verdolaga , from Colombia (Araneae: Mygalomorphae: Theraphosidae)
ABSTRACT A new species of Pamphobeteus Pocock, 1901, is described from the Colombian Andes, Medellín, Antioquia. The biochemistry and molecular characteristics of the venom of this new species (previously identified as Pamphobeteus aff. nigricolor ) has been already described. A detailed taxonomic study, comparing this species with holotypes and additional

2. A new species of Pterinopelma (Araneae: Theraphosidae) from the highlands of the state of Minas Gerais, Brazil and description of the male of P. sazimai
ABSTRACT We describe a new species of tarantula from the highlands of the state of Minas Gerais, Brazil. Males of the new species can be distinguished from congeners by having palpal bulb keels weakly developed, and metatarsus I strongly curved, touching apex of retrolateral spur when folded. Females can be distinguished by the color pattern, carapace and le

3. Pharmacological characterization of venoms from three theraphosid spiders: Poecilotheria regalis, Ceratogyrus darlingi and Brachypelma epicureanum
Abstract Background Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms from three taxonomically different theraphos

4. A new species of Phrixotrichus (Araneae, Theraphosidae) from southwestern Argentina and new distributional data for P. vulpinus
ABSTRACT A new species of Phrixotrichus Simon, 1889, P. pucara sp. nov., is described and illustrated based on a male from Pucará river, Neuquén province, Argentina. Male can be distinguished from all other species of the genus by the presence of a long strong spine on inner face of prolateral branch of tibial apophysis; also, it differs from P. scrofa (Mo

5. Tmesiphantes mirim sp. nov. (Araneae: Theraphosidae) from the Atlantic Forest of Bahia, Brazil, biogeographical notes and identification keys for species of the genus
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

6. Uma nova espécie de Tmesiphantes (Araneae, Theraphosidae) do Estado do Pará, Brasil
Uma nova espécie de Tmesiphantes Simon, 1892, T. aridai sp. nov., é descrita e ilustrada baseada em três machos e três fêmeas coletadas na Floresta Nacional do Tapajós, Santarém, Estado do Pará, Brasil. Os machos distinguem se de T. perp Guadanucci & Silva, 2012 pelo aspecto do palpo copulador com uma projeção tegular basal inconspícua, apresentan

7. Purification and characterization of a hyaluronidase from venom of the spider Vitalius dubius (Araneae, Theraphosidae)
BackgroundVenom hyaluronidase (Hyase) contributes to the diffusion of venom from the inoculation site. In this work, we purified and characterized Hyase from the venom of Vitalius dubius (Araneae, Theraphosidae), a large theraphosid found in southeastern Brazil. Venom obtained by electrical stimulation of adult male and female V. dubius was initially fractio

8. On the Brazilian Amazonian species of Acanthoscurria (Araneae: Theraphosidae)
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 re

9. Description of two new species of Plesiopelma (Araneae, Theraphosidae, Theraphosinae) from Argentina
Two new species of Plesiopelma Pocock, 1901 from northern Argentina are described and diagnosed based on males and habitat descriptions are presented. Males of Plesiopelma paganoi sp. nov. differ from most of species by the absence of spiniform setae on the retrolateral face of cymbium, aspect of the palpal bulb. Plesiopelma aspidosperma sp. nov. differs fro

10. Morphology, evolution and usage of urticating setae by tarantulas (Araneae: Theraphosidae)
Urticating setae are exclusive to New World tarantulas and are found in approximately 90% of the New World species. Six morphological types have been proposed and, in several species, two morphological types can be found in the same individual. In the past few years, there has been growing concern to learn more about urticating setae, but many questions stil

11. Avicularia rickwesti sp. nov., a remarkable new species of Avicularia (Theraphosidae: Aviculariinae) from Dominican Republic
A remarkable new species of Avicularia Lamarck, 1818, Avicularia rickwesti sp. nov., is described from Dominican Republic. Female specimens of the new species are unusual by having two very short and broad spermathecae with distal half strongly sclerotized, a feature not found in any other aviculariine. Additionally, it has the leg coxae with spiniform setae

12. Sobre Munduruku, um novo gênero de Theraphosidae da Amazônia Oriental (Araneae, Mygalomorphae)
Munduruku gen. nov., é proposto para a espécie-tipo Munduruku bicoloratum sp. nov., de Juruti, e Santarém, Pará, Brasil. O principal caráter diagnóstico de Munduruku gen. nov. é a presença de uma quilha subapical lancelotada no bulbo copulatório do macho, único no grupo basal de Theraphosinae com cerdas urticantes do tipo III-IV. A espermateca da f
