Holocneminus huangdi Tong & Li 2009: 24 , figs 20–23, 48–53. Tong 2013: 61, figs 32T–W, 81A–F.

Type material examined. Holotype: male (IZCAS-Ar 21428), Huangdi Cave (18°57.720′N, 109°8.373′E), Dongfang , Hainan, China, 20 March 2005, Y. Song, X. Han, Y. Tong and G. Deng leg. Paratypes: 3 males (IZCAS-Ar 21429–21430, 21439) and 4 females (IZCAS-Ar 21443–21445, 21448), same data as holotype ; 3 females (IZCAS-Ar 21474–21476), Baoyao Cave (19°6.092′N, 109°1.208′E), Qicha Town, Changjiang County, Hainan, China, 2–3 April 2005, collector same as holotype .

Diagnosis. This species can be easily distinguished from C. dao sp. nov. by procursus with short, pointed prolatero-subdistal apophysis (arrow in Fig. 2C ; elongated prolatero-subdistal apophysis in C. dao sp. nov., arrow 1 in Fig. 4C ) and pointed dorsal apophysis (arrow in Fig. 2D ; absent in C. dao sp. nov., Fig. 4D ), by procursus not protruding dorso-distally ( Fig. 2C ; strongly protruding in C. dao sp. nov., arrow 2 in Fig. 4C ), by male chelicerae pointed proximally (arrow in Fig. 3C ; blunt in C. dao sp. nov., arrow in Fig. 5E ), without frontal apophyses (present in C. dao sp. nov., fa in Fig. 5E ) and distal apophyses short cone-shaped (da in Fig. 3C ; distal apophyses with sclerotized cones, serrated in lateral view in C. dao sp. nov., da in Fig. 5E ), and by external female genitalia with small median apophysis (ma in Fig. 3A ; median apophysis large, proximally wide and distally sharply narrow in C. dao sp. nov., ma in Figs 5A–C ).

Distribution. China (Hainan, type locality; Fig. 1 ).
