Belisana zhangi Tong and Li 2007: 505, figs 1–6.

Material examined.

China • 1 ♂; Guizhou, Anshun, Puding County, Huachu Town, Jinqian Cave ; 26 ° 14.835 ' N, 105 ° 37.521 ' E; 3 May 2005; collector unknown; IZCAS - Ar 45177 • 3 ♀; same data as for preceding; IZCAS - Ar 45178 –80 .

Diagnosis.

The species resembles B. yuhaoi Yang & Yao, 2023 ( Yang et al. 2023 a: 178, figs 2 A, B, 3 A – D, 4 A – H) by having similar bulbal apophysis (hooked; Fig. 17 C ) and epigyne (epigynal pockets on posterior part of epigynal plate, epigynal plate posteriorly curved; Figs 17 A , 25 E ), but can be distinguished by procursus with nearly angular ventro-subdistal membranous lamella (arrow 1 in Figs 16 C , 23 C vs nearly round) and curved retrolateral membranous flap (f in Figs 16 D , 23 D vs angular), by male cheliceral distal apophyses pointing inwards (da in Fig. 17 D vs downwards), and by vulval pore plates long elliptic (pp in Figs 17 B , 25 F vs nearly triangular).

Habitat.

The species was found in the dark zone inside the cave.

Distribution.

China (Guangxi, type locality; Guizhou, Fig. 1 ).
