TYPE MATERIAL. — Holotype: China, Henan Province, Neixiang County, Qiliping Town, Sandaohe Village, Tianxin Cave (33°21’N, 111°53’E), 24.VI.2005, leg. Q. Wang & Y. Tong, ♂ (MNHN). Paratypes: same data as holotype, 12 ♂♂, 6 ♀♀ (IZCAS); 2 ♂♂, 2 ♀♀ (MNHN).

ETYMOLOGY. — The specific name is derived from the type locality.

DIAGNOSIS. — The new species is similar to L. xui Chen, Gao & Zhu, 2000, distributed in Guizhou Province, but can be distinguished by having the chelicera with seven promarginal teeth, instead of nine as in L. xui; the eyes are normal-sized, but reduced in L. xui; the ventral long spines of male palpal tibia is two, one strong and one relatively slender; and also by the different shape of lamina of male palpal bulb.
