Holotype ♂ (IZCAS-Ar34067, zz890, KY778824): China: Guangxi Zhuang Autonomous Region: Guilin City: Yangshuo County, Xingping Town, Luotian Village, Luotian Cave, 24°56.731'N, 110°31.459'E, elevation: 217 m, 17.XII.2013, H. Zhao leg. Paratypes: 3♂♂4♀♀ (IZCAS-Ar34068-Ar34074), same cave as holotype, elevation: 241 m, 8.XII.2015, X. Zhang and Z. Chen leg.

Etymology.

The specific name is an adjective and refers to the type locality, Xingping Town.

Diagnosis.

Males of Guilotes xingpingensis sp. n. differ from G. ludiensis sp. n. by the patellar apophysis short, lateral tibial apophysis narrow, conductor wide with flat outgrowth and small lamella (Figure 5C). Females differ from G. ludiensis sp. n. by the sail-shaped copulatory ducts and fertilization ducts wide and long (Figure 6B).
