üĝű나ffiHŔ (ṳAE) ( Fig. 4 A­F)

Material examined. Holotype: ♂, dwarf bamboo area around Deokju Temple (36°51′43″N, 128°05′42″E, alt. 267 m), 2.9 km south­southwest of the summit of Mt. Weolak, Hansu­myeon , Jecheon­si , Chungcheongbuk­do, 7 September 2007, S. Y. Kim.

Etymology. The specific name comes from the type lo­ cality, Mt. Weolak.

Diagnosis. The male palp of L. weolakensis n. sp. is very similar to that of L. jangseongensis n. sp. in the femur with many strong spines, the tarsus unbranched retrolaterally, with two spurs at tip and a long proximal prolateral spur but without transverse depression, the conical embolus, the triangular retrolateral sclerite with serrated tip, and not having prolateral sclerite, but can be easily distinguished from the latter by the tibial without nodule with a spine and the long sword­like median sclerite ( Fig. 4 E­F).
