Holotype : ♂ , mixed forest ( 37°58 ʹ 15 ʺ N , 128°25 ʹ 39 ʺ E , alt. 452 m ), Jindong-ri, Girin-myeon, Inje-gun, Gangwon-do, 23 September 2009 , S. Y. Kim. Paratypes : 7♂♂ , 4$$, same data as holotype . Etymology. The specific name comes from the type lo- cality, Jindong Village. Diagnosis. The new species is similar to P. lingulatus Gao, Gao and Zhu, 2002 in the spines on the distal part of procursus ridge, but can be distinguished from the latter by the distal processes of the procursus, uncus, and the genitalia of female ( Fig. 2 A-F).
