ṻďű나ffiHŔ (ṳAE) ( Fig. 2 A­G)

Material examined. Holotype: ♂, grassland near Sangseonbul Hamlet (35°50′05″N, 128°10′15″E, alt. 475 m), 4.6 km east­northeast of the summit of Mt. Gaya , Suryunmyeon , Seongju­gun, Gyeonsangbuk­do, 25 May 2007, J. Y. Kim.

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

Diagnosis. The male palp of L. gayaensis n. sp. is similar to that of L. songniensis Seo, 2015 in the femur with many strong spines, the tibia without apophysis, and in the tarsus without transverse depression but with a spur at tip, but it can be easily distinguished from the latter by the conical embolus, the spine­like prolateral sclerite, the shoehorn­like median sclerite, the skinny triangular retrolateral sclerite with serrated tip, and the tarsus unbranched retrolaterally, with much longer proximal prolateral spur ( Fig. 2 E­G).
