Description. Body length 2.8–3.8 mm. Body (Fig. 1 A) generally dark brown; antennae and pronotum paler; legs yellowish brown. Head narrower than pronotum; eyes prominent, about as long as tempora; antennae long and slender, antennomeres 4–10 slightly elongate, 11 about as long as preceding two combined; anterior margin of labrum emarginate; a-sensillum relatively long; prementum with medial pseudopores absent and lateral pseudopores present. Pronotum slightly transverse, approximately 1.15–1.20 times as wide as long, widest in apical third; pubescence in midline directed anteriorly. Elytron approximately 1.85 times longer than wide, postero-lateral margin very weakly sinuate. Male tergite VIII with 5 macrosetae on each side of midline, posterior margin truncate; male sternite VIII with 7 macrosetae on each side of midline, posterior margin broadly round; posterior margin of female tergite VIII emarginate; posterior margin of female sternite VIII round. Aedeagus as in Figs. 2 A–C.
Material examined. KOREA: 4 ex., Phjongjang, 16 v 1974, ISEA; Gangwon prov.: 3 ex., Kymgang-san Mts., 16–18 vi 1974, ISEA
