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