ARTÍCULO: REDESCRIPTION OF FUFIUS FUNEBRIS VELLARD, 1924 AND DESCRIPTION OF FUFIUS LUCASAE SP. N. WITH COMMENTS ON CTENOCHELUS MACULATUS MELLO-LEITÃO, 1923 (MYGALOMORPHAE, CYRTAUCHENIIDAE) José Paulo Leite Guadanucci & Rafael Prezzi Indicatti Abstract: To date, the family Cyrtaucheniidae has been recorded, in South America, only from the Amazon region, central and south-eastern Brazil. In this paper, the genus Cteno- chelus Mello-Leitão is removed from the synonymy of Bolostromus Ausserer, and synonymyzed with Stenoterommata Holmberg (Nemesiidae). A new name, Stenoterommata melloleitaoi, is proposed for C. maculatus, preoccupied by Bertkau. In addition we present the redescription of Fufius funebris Vellard 1924, from the Brazilian cerrado, and the description of Fufius lucasae sp. n. from the Atlantic Forest in south- eastern Brazil, the first record of this family from an Atlantic Forest area. Key words: Araneae, Cyrtaucheniidae, Ctenochelus, Fufius, Atlantic Forest, Brazil. Taxonomy: Fufius lucasae sp.n. Redescripción de Fufius funebris Vellard, 1924 y descripción of Fufius lucasae sp. n. y comentarios sobre Ctenochelus maculatus Mello-Leitão, 1923 (Mygalomorphae, Cyrtaucheniidae) Resumen: Hasta la fecha, la familia Cyrtaucheniidae se ha registrado en Suramérica sólo de la región amazónica (centro y sureste de Brasil). En el presente trabajo se revoca la sinonimia del género Ctenochelus Mello-Leitão con Bolostromus Ausserer, y se sino- nimiza Ctenochelus con Stenoterommata Holmberg (Nemesiidae). Se propone un nombre nuevo, Stenoterommata melloleitaoi, para C. maculatus, preocupado por Bertkau. Por otra parte, se presentan la redescripción de Fufius funebris Vellard, 1924, del Cerrado brasileño, y la descripción de Fufius lucasae sp. n. del Bosque Atlántico en el sureste de Brasil, que constituye el primer registro de la familia para el área. Palabras clave: Araneae, Cyrtaucheniidae, Ctenochelus, Fufius, Bosque Atlántico, Brasil. Taxonomía: Fufius lucasae sp.n. Introduction The family Cyrtaucheniidae includes 125 species distributed in three sub- families: Cyrtaucheninae, from the Southern Mediterranean region and Afri- ca; Euctenizinae, from North America; and Aporoptychinae, from Western Africa and Central and South Americas. Aporoptychinae is the only one with Neotropical species and includes seven genera, of which five present Neotropical records: Acontius Karsch, 1879, Bolostromus Ausserer, 1875, Fufius Simon, 1888, Rhytidicolus Simon, 1889 and Bolostromoides Schiapelli & Gerschman, 1945 (Platnick, 2004; Raven, 1985; Bond & Opell, 2002). In Brazil, Cyrtaucheniidae is represented by the genera Bolostromus, Fufius and Rhytidicolus (Platnick, 2004), the latter represented solely by an undescribed species from Amazonas (Höfer & Brescovit, 2001; Brescovit et al., 2002). The genus Fufius includes, to date, eight species described from northern South America and Central America. In Brazil, it is recorded mainly from the Amazon region and Amazonian influenced environments. Bolostromus is more widely distributed and, until now, included the only record of Cyrtaucheniidae from an Atlantic Forest, with B. maculatus (Mello-Leitão, 1923), from São Paulo, Brazil. This species was originally described in Ctenochelus by Mello-Leitão (1923) and transferred to Bolos- tromus by Raven (1985). Nevertheless, this record should not be considered since we here propose the transfer of Ctenochelus maculatus Mello-Leitão, 1923 to the genus Stenoterommata. In this paper the genus Ctenochelus Mello-Leitão, is removed from the synonymy of Bolostromus Ausserer, and synonymyzed with Stenoterommata ARTÍCULO: Redescription of Fufius funebris Vellard, 1924 and description of Fufius lucasae sp. n. with comments on Ctenochelus maculatus Mello- Leitão, 1923 (Mygalomorphae, Cyrtaucheniidae) José Paulo Leite Guadanucci Museu de Zoologia da Universidade de São Paulo, Av.
