( Fig. 4 View FIG )

TYPE MATERIAL. — Holotype: China, Beijing City, Fangshan District, Shidu Town (39°42’N, 115°37’E), Liuhe Village , Beipo Cave , 11.V.2005, leg. Q. Wang, ♂ ( MNHN). GoogleMaps

Paratypes: same locality as holotype, 5.IX.2006, leg. S. Li, Y. Lin & J. Liu, 6 ♂♂, 25 ♀♀ ( IZCAS). — Same locality as holotype, 5.IX.2006, leg. S. Li, Y. Lin & J. Liu, 3 ♂♂, 3 ♀♀ ( MNHN).

ETYMOLOGY. — The specific name comes from Latin, set, hairs, and combined with suffix fera, bearing, in reference to the hairs presented on carapace.

DIAGNOSIS. — The new species is similar to L. handeulgulensis Namkung, 2002 ( Namkung 2003) , but can be distinguished by the presence of many long spines on ventral surface of male palpal femur, and the presence of hook-like projection on male palpal tibia.
