Type material. Holotype. [KOREA] ♂, Gwangrung, Province Gyeonggi, 3 vi 1999 (leg., B.K. Byun), genitalia slide no. 854. Paratypes. [KOREA] 1♀, Mt. Chenggye-san, Province Gyeonggi, 15 v 1997 (Y.M. Park & J.S. Lee); 1♀, Yangyang, Province Gangweon, 30 v 1987 (K. T. Park), genitalia slide no. 3464; 1♂, Chuncheon, N 37.961788, E 127.683416, Province Gangweon, 14 v 1991 (leg., B.K. Byun & Y.D. Kwon)-coll. SELHNU, genitalia slide no. 3467.
Diagnosis. The new species is similar to members of the allied genera, Caenognosis incisa Walsingham, 1900, Leurogyia peristictum Common, 1965, and Daulocnema epicharis Common, 1965 in wing pattern, color, and the shape of the forewing termen, but it can be distinguished by the elongate uncus, the golf club-shaped hami, the curved costa of the valva, and a nearly straight aedeagus. In wing venation, the new species is quite similar to Leurogyia peristictum, with the forked R 4 and R 5 near the apex in the forewing; however, in the latter, the veins are positioned near the apex at the costa and beneath the apex at the termen, respectively, whereas in N. koreana R 4 and R 5 are positioned together near the apex at the costa.
Description. Head (Figs 2, 3) with short whitish rough scale tufts on frons and with yellowish brown rough scales along the compound eye, base of antenna, and vertex; proboscis short; labial palpus with creamy white second segment, somewhat sub-triangular in the frontal view, rather broadened downwards with long scales; apical segment narrowed, slightly porrect, subacute, with appressed short scales.
Thorax and legs with smooth scales. Forewing (Figs 1, 4). Wingspan 11.5 mm in male, 13.5 mm in female, narrow, elongate, costa gently arched basally, then nearly straight toward apex, apex narrowed and subacute, strongly produced, termen deeply concaved beneath apex, tornus somewhat broadly rounded; ground color creamy white, blackish brown scales from base to 3/4 at lower half of the forewing, then somewhat weak in color to termen; apical half of costa nearly straight, with five narrow yellowish brown streaks from middle to near apex, rather darkened near costa, then abruptly curved at apex forming a protruded portion with a short and narrow white streak inside of apical area; termen strongly concaved beneath apex, then rounded to the broad tornus; three pale yellowish short streaks along the termen with a small blackish dot on the concaved area near termen; cilia short near apex, then rather long along termen and tornus. Hindwing (Figs 1, 4), a bit narrower than forewing, slightly acute apically, Sc fused with discal cell to beyond one-half, Rs and M 1 practically coincident from upper angle of cell.
