﻿AbstractA new genus of the subfamilyCoelotinaeF. O. Pickard-Cambridge, 1893,Yunguiriusgen. nov.is described, comprising two new species and three species previously described inDraconariusOvtchinnikov, 1999, all from southwest China:Y.duogesp. nov.(♀),Y.xiangdingsp. nov.(♀),Y.ornatus(Wang, Yin, Peng & Xie, 1990)comb. nov.(♂♀) (the type species ofYunguiriusgen. nov.),Y.subterebratus(Zhang, Zhu & Wang, 2017)comb. nov.(♀), andY.terebratus(Peng & Wang, 1997)comb. nov.(♂♀). Molecular analyses supportYunguiriusgen. nov.as a monophyletic group, with theSinodraconariusclade as its sister group:Yunguiriusgen. nov.+ (Hengconarius+ (Nuconarius+Sinodraconarius)).
