South Korea, Gangwon-Prov., Pyeongchang-Gun, Mt. Odaesan.
Body length approximately 1.3–1.4 mm. Dorsum almost concolorous, brown, or dark brown. Head and pronotum strongly microreticulate, sparsely and very minutely punctate. Elytra almost smooth, sparsely and very minutely punctate, and densely and transversely strigose. The median lobe of aedeagus relatively thick and feebly curved at lateral margins and bearing a relatively small nipple at apex in dorsal view.
Body 1.31–1.39 mm in length, approximately 1.8 times as long as wide (Fig.
Head approximately 1.6 times as wide as long, strongly microreticulate, sparsely and very minutely punctate; head length approximately 0.54 times pronotum length; head width approximately 0.48 times pronotum width; antennomeres 1–4 and 11 longer than wide; antennomere 5–7 almost as long as wide; other antennomeres wider than long; antennomere 11 approximately1.3 times as long as wide (Fig.
Pronotum approximately 1.8 times as wide as long, strongly microreticulate, sparsely and very minutely punctate; pronotum length approximately 0.58 times elytron length; pronotum width almost same as elytron width.
Scutellum weakly microreticulate and almost impunctate or sparsely and very minutely punctate.
Elytra almost as long as wide or slightly wider than long, widest at approximately basal 1/6, almost smooth, sparsely and very minutely punctate, and densely and transversely strigose (Fig.
Legs show no sexual dimorphism on protarsi and normal shape for
Meso- and metaventrites strongly microreticulate, almost impunctate, and glabrous; abdominal ventrites strongly microreticulate, almost impunctate, and bearing sparse and very fine pubescences.
Male. Aedeagus generally thick (Figs
