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

Abstract

Acanthoscurria natalensis Chamberlin, 1917 is redescribed. The following species are considered junior synonyms of A. natalensis: A. cursor Chamberlin, 1917, A. fracta Chamberlin, 1917, A. rondoniae Mello-Leitão, 1923, A. chiracantha Mello-Leitão, 1923, and A. parahybana Mello-Leitão, 1926. All examined specimens, including the types, share the same general aspect, morphology of the sexual organs, color, and measurements. Acanthoscurria natalensis resembles A. paulensis Mello-Leitão, 1923 and A. chacoana Brèthes, 1909 in the general aspect, size, and by the morphology of the sexual organs: male palpal bulb with embolus ending like a shell, due to the prolateral and superior keels. It can be distinguished from these two species by the less developed keels and the longer embolus. The female resembles A. paulensis and A. chacoana by the fused base of the spermathecae and differs by the more evident lobes, projected from base. The distribution of A. natalensis is expanded to Brazilian states covering the Caatinga and the Cerrado biome

Biochemical and structural characterization of a protein complex containing a hyaluronidase and a CRISP-like protein isolated from the venom of the spider Acanthoscurria natalensis

“…The genus Acanthoscurria (Theraphosidae) comprises 28 species of tarantula (caranguejeira) spiders, distributed predominantly throughout countries in South America [23]. Acanthoscurria natalensis is a non-aggressive species with wide distribution in the Brazilian Caatinga and Cerrado biomes [24]. For this…”

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.…”
