A first phylogenetic analysis reveals a new arboreal tarantula genus from South America with description of a new species and two new species of Tapinauchenius Ausserer 1871 (Araneae Mygalomorphae Theraphosidae)

摘要

Based on molecular and morphological phylogenetic analyses a new genus of Theraphosidae is described, Pseudoclamoris>gen. n.Tapinaucheniusgigas and Tapinaucheniuselenae are transferred to Pseudoclamoris and a new species of Pseudoclamoris from the Amazon Region is described: P.burgessi>sp. n. Two new species of Tapinauchenius from the Caribbean are described: T.rasti>sp. n. and T.polybotes>sp. n.Tapinaucheniussubcaeruleus is considered a nomen dubium. Psalmopoeinae subfamily is diagnosed based on molecular and morphological phylogenies, and Pseudoclamoris>gen. n. and Ephebopus Simon, 1892 are included. A taxonomic key for Psalmopoeinae genera Tapinauchenius, Pseudoclamoris, Psalmopoeus, and Ephebopus is provided.
