Redescription and new distribution records of Acanthoscurria paulensis (Araneae: Mygalomorphae: Theraphosidae)

On the Taxonomy ofAcanthoscurriaAusserer from Southeastern Brazil with Data on the Natural History ofA. gomesianaMello-Leitão (Araneae, Mygalomorphae, Theraphosidae)

“…The other two species, A. cunhae and A. melanotheria, were considered Species inquirendae because the types are lost and the descriptions are too resumed to identify the species. Acanthoscurria guaxupe was considered a junior synonymy of A. paulensis [8] and A. chiracantha of A. natalensis Chamberlin, 1917 [9]. We concluded that A. paulensis and A. gomesiana are the only valid species for the southeastern Brazil.…”

Four new species and two new genera of theraphosid spider from Bolivia (Araneae: Theraphosidae)

“…Remarks: Acanthoscurria sacsayhuaman Ferretti, Ochoa & Chaparro, 2016 was described from Peru and placed in the genus Acanthoscurria Ausserer, 1871 despite the lack of stridulatory setae on the coxa and trochanter of leg I, the presence of which has been regarded as a primary feature for the genus Acanthoscurria since its first recognition (e.g. Pocock 1901Pocock , 1903Mello-Leitão 1923;Vellard 1924;Timotheo-da-Costa 1960;Schiapelli & Gerschman 1964;Piza 1972;Bertani & Carla-da-Silva 2004;Lucas et al 2010Lucas et al , 2011Rodríguez-Manzanilla & Bertani 2010;Gonzalez Fihlo et al 2012;Paula et al 2014;Gabriel 2020). The absence of stridulatory setae was used as the primary feature to differentiate it from other Acanthoscurria species (see Ferretti, Ochoa & Chaparro 2016).…”

Una nueva especie de Acanthoscurria (Araneae: Theraphosidae: Theraphosinae) sin órgano estridulador, del sur de Perú

“…Koch 1841, Mello-Leitão 1923 enfatizaban caracteres ambiguos como el color, la posición de los ojos y sus distancias, pero no presentaban ilustraciones o descripciones detalladas del bulbo del macho o de los receptáculos seminales de la hembra, caracteres hoy en día relevantes en la taxonomía de arañas (Lucas et al 2011). A pesar de ello, en trabajos recientes se han revisado varias especies a partir de numerosos ejemplares de museo, particularmente provenientes de la fauna de Brasil, lo que ha permitido la redescripción de varias especies basándose en el estudio morfológico del material tipo (Bertani & Carla-daSilva 2004, Lucas et al 2010, Lucas et al 2011, Gonzalez-Filho et al 2012, Paula et al 2014.…”
