Holotype ♂: “S-KOREA, Gyeonggi-do, Gapyeong-gun district, 2 km E Hwaak-san (Mt.) confluence, forest w/ Magnolia, 890 m \ wet mosses on rocks in and at fast stream, flotation (15A) 37°59’52”N, 127°31’36”E 11.IX.2010, Makranczy et al. ” (TMB).
Description. 6.0 mm long (2.9 mm, abdomen excluded). Black, moderately shiny; mouthparts reddish brown, last segment of maxillary palpi somewhat darker; antennae black brown, basal three segments dark reddish brown, last segment reddish; legs pale brown to reddish brown, medial faces of metatibiae infuscate.
Head about as long as wide, hind angles broadly rounded, tempora slightly convex, 1.6 times as long as eyes; medial interocular punctures separated by twice the distance between medial and lateral interocular punctures, lateral interocular punctures only slightly nearer to medial margin of eye than to medial interocular punctures; disc of head mostly impunctate, except for a few larger punctures between tempora and vertex; tempora sparsely punctate; surface of head

with dense and distinct, somewhat vermiculate, short-meshed microsculpture; antennae very short, segments 2 and 3 almost equal in length, segment 4 very slightly oblong, segment 5 as long as wide, segments 6–10 slightly transverse. Pronotum subparallel-sided, 1.2 times as long as wide, anterior margin straight, base broadly rounded; dorsal rows each with five punctures; microsculpture similar to that on head.
Elytra along sides longer than pronotum along midline, rather coarsely, moderately densely and irregularly punctate, punctures separated by 1–3 puncture diameters in transverse direction.
Abdominal tergites III–VI with two basal lines, elevated area between basal lines almost glabrous; remaining portion of all tergites rather sparsely, finely punctate; male sternite VIII (Fig. 3) with deep medio-apical emargination, with extensive semi-membranous extension.
Aedeagus (Fig. 1) with apical portion of median lobe sinuately narrowed towards truncate apex; in lateral view (Fig. 1 b) with apical portion almost straight. Paramere (Fig. 1 c) distinctly widened towards apex, deeply bilobed, with numerous peg setae along apical and lateral margin, basad reaching about half length of apical portion of paramere; with two pairs of very large setae at apical margin and two pairs of rather short and fine setae laterally at about half length of apical portion of paramere.
Female unknown.
Distribution. The species is at present known only from the type locality.
Etymology. The species is named after its provenance, the Korean peninsula.
