Paratachycines (Hemitachycines) xiai Zhang, Liu & Bi, 2009: 67–68 .

Type specimen: male; type locality: Longdong, Jinan, Shandong; location of type specimen: Shanghai Entomological Museum, Chinese Academy of Science (SEM, CAS) .

Material examined. 1♂, Shandong province, Jinan, Longdong, alt. 500–700m, collector unknown ; 1♂ 1♀, Henan province, Songxian, Baiyunshan, 9–20-VIII-1996, leg. Zuyao LIU et al .; 33♀♀, Shandong province, Taian, Tianwa- icun, alt. 200m, 12~ 13-IX-2017, leg. Xianwei LIU et al .; 29♂♂ 52♀♀, Shandong province, Taian, Taishan, Shixi- ayuan, alt. 190–300m, 12~ 13-VIII-2019, leg. Xianwei LIU, Hanqiang WANG & Yanya QIN ; 24♂♂ 35♀♀, Shandong province, Linyi, Mengshan, alt. 440–500m, 11-VIII-2019, leg. Xianwei LIU, Hanqiang WANG & Yanyan QIN .

Distribution. China (Shandong, Henan).

Discussion. Body colour of all specimens from Mengshan is brown (Figs. 25–26), body of all specimens from Taishan black (Figs. 27–28), but male genitalia and female subgenital plate of specimens from above both collected locations are virtually the same. The phylogenetic tree also indicated that individuals from above two locations formed a branch separately (unpublished), so we consider those differences may be related to the habitat.
