Draconarius subterebratus Zhang, Zhu & Wang, 2017 in Zhu et al. 2017: 379, fig. 245A, B.

Type material

(not examined). Holotype ♀ (MHBU): China: Guizhou Province: Zunyi City: Daozhen County, Dashahegou Nature Reserve, Xieshiyan Cave to Dashahe River, 18.VIII.2004, Z. Zhang leg. Paratypes: 3♀♀ (MHBU): same data as the holotype.

Diagnosis.

Yunguirius subterebratus can be distinguished from other species of this genus as follows: 1) atrium cordiform (fig. 245A in Zhu et al. 2017) in Y. subterebratus , but inverted trapezoid (Fig. 3A ; fig. 53 in Wang et al. 1990) in Y. ornatus , or subrounded (Fig. 2A ) in Y. duoge sp. nov. and (fig. 28 in Peng and Wang 1997) Y. terebratus ; and 2) posterior epigynal sclerite longer than wide, waist-drum-shaped (fig. 245A in Zhu et al. 2017) in Y. subterebratus , but vase-shaped (Fig. 4A ) in Y. xiangding sp. nov., or rectangular (Figs 2A , 3A ; fig. 53 in Wang et al. 1990; fig. 28 in Peng and Wang 1997) in others.
