Holotype ♂ (Uchida collection). Sesok-pyongjon , Chiri-san , Kyongsang-nam-do, [Republic of] Korea Material examined. Republic of Korea : Chungbuk , Songchon-Myeon , Dungeon-li , near Doma Pass , 750 m , 2-26 May 2006 , P. Tripotin , Malaise trap in forest on small stream, 6♂ , 10♀ ( USNM ). Comments. This species has apparently not been reported since the original description based on 9 male and 20 female specimens from a single locality (Stark & Nelson 1994). These specimens agree in most details with the original description, but a few scattered setal-spines and a covering of fine, short microtrichia occur on the lateral aedeagal lobes of the new specimens, in contrast to the type series in which the lateral lobes are said to be “…well developed but without armature”.
