Falcileptoneta sunchangensis View in CoL n. sp. ṪǧḦ나ffiĄŔ (ṳAE) ( Fig. 4 A­I)

Material examined. Holotype: ♂, mixed forest (35°28′ 05″N, 126°52′21″E, alt. 427 m), 3.5 km north­northwest of Baekyang Temple in Mt. Baekam, Bokheung­myeon, Sunchang­gun , Jeollabuk­do, 13 May 2006, B. K. Seo GoogleMaps . Paratype: 5♂♂, 3$$, same data as holotype GoogleMaps ; 1♂, mixed forest (35°29′04″N, 126°54′55″E, alt. 207 m), 1.3 km east­southeast of Naejang Temple in Mt. Naejang , other data same as holotype GoogleMaps .

Etymology. The specific name comes from the type lo­ cality, Sunchang County.

Diagnosis. The male palp of F. sunchangensis n. sp. resembles those of F. bifurca Seo, 2015 and F. naejangensis Seo, 2015 in the shape of tarsus, and in having two retrolateral apophyses on the distal end of the tibia, but can be easily distinguished from the latters by the tibia with a simple spine­like ventral apophysis and a thick spur­like apophysis on the distal part, the large sickle­like embolus tip, and the broad retrolateral sclerite of palpal bulb ( Fig. 4 E­H).
