Yunguirius gen. nov., a new genus of Coelotinae (Araneae, Agelenidae) spiders from southwest China

Abstract

A new genus of the subfamily Coelotinae F. O. Pickard-Cambridge, 1893, Yunguirius gen. nov. is described, comprising two new species and three species previously described in Draconarius Ovtchinnikov, 1999, all from southwest China: Y. duoge sp. nov. (♀), Y. xiangding sp. nov. (♀), Y. ornatus (Wang, Yin, Peng & Xie, 1990) comb. nov. (♂♀) (the type species of Yunguirius gen. nov.), Y. subterebratus (Zhang, Zhu & Wang, 2017) comb. nov. (♀), and Y. terebratus (Peng & Wang, 1997) comb. nov. (♂♀). Molecular analyses support Yunguirius gen. nov. as a monophyletic group, with the Sinodraconarius clade as its sister group: Yunguirius gen. nov. + (Hengconarius + (Nuconarius + Sinodraconarius)).
