Catanduba, a new Theraphosinae spider genus from Central Brazil (Araneae, Theraphosidae)

Flávio Uemori Yamamoto, Sylvia M. Lucas, Antonio Domingos Brescovit ,2012

A new genus, Catanduba, is proposed and supported on the cladistic analysis with the following synapomorphies: embolus tapering abruptly from half of the length, embolus tooth associated with PIK and a triangular basal nodule on male metatarsus I. Homoeomma simoni and Plesiopelma flavohirtum are transferred to Catanduba and five new species are described: 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.).

Revalidation and revision of the genus Magulla Simon 1892 (Araneae, Mygalomorphae, Theraphosidae)

Rafael Prezzi Indicatti, Sylvia M. Lucas, José Paulo Leite Guadanucci, Flávio Uemori Yamamoto ,2008

The genus Magulla Simon 1892 is revalidated and redescribed. The female of the type species M. obesa Simon 1892 is redescribed and the male is described for the first time. Magulla janeirus (Keyserling 1891) is considered a valid species. Magulla symmetrica Bucherl 1949 is transferred to Plesiopelma Pocock 1901, and considered a junior synonym of P. insulare (Mello-Leitao 1923). Additionally, two new species are described from Brazil: M. buecherli n. sp. from Ilhabela, Sao Paulo and M. brescoviti n. sp. from Sao Francisco de Paula, Rio Grande do Sul.

Revision of the genus Tmesiphantes Simon (Araneae, Mygalomorphae, Theraphosidae)

Flávio Uemori Yamamoto, Sylvia M. Lucas, José Paulo Leite Guadanucci, Rafael Prezzi Indicatti ,2007

The genus Tmesiphantes Simon, 1892 is revised. The type-species, T. nubilus Simon, 1892, is redescribed and three new species are described from the state of Bahia, Brazil: T. amadoi sp. nov., T. bethaniae sp. nov. and T. caymmii sp. nov. In addition, Tmesiphanthes physopus Mello-Leitão, 1926 and T. minensis Mello-Leitão, 1943 are transferred to Plesiopelma Pocock, 1901. T. chickeringi is considered species inquirenda.

Description of Guyruita gen. nov. and two new species (Ischnocolinae, Theraphosidae)

José Paulo Leite Guadanucci, Sylvia M. Lucas, Rafael Prezzi Indicatti, Flávio Uemori Yamamoto ,2007

The genus Guyruita gen. nov. and two new species from Brazil are described. Holothele waikoshiemi (Bertani & Araújo, 2005) from Venezuela is transferred here to the new genus. Guyruita gen. nov. differs from the remaining Ischnocolinae by the following features: labium densely occupied by a lot of cuspules (more than 100), intercheliceral intumescence absent, posterior sternal sigilla remote from margin, tarsal claws without teeth, tarsal scopula I-II undivided (tarsus II with a line of sparse setae, which does not divide the scopula), III-IV divided.
