Genus Nabangana gen. nov.
Type species: Nabangana koreana sp. nov.
Diagnosis. The new genus is somewhat similar in appearance to members of the tribe Enarmoniini, but it can be easily distinguished by the concaved termen beneath the apex in the forewing, the presence of hami and a subtriangular lobe on the valva in male genitalia, and a signum bearing numerous long spines in female genitalia. Also, the new genus is similar to the related genera, Trymalitis Meyrick, 1905, Caenognosis Walsingharn, 1900, Leurogyia Common, 1965, and Daulocnema Common, 1965, but it is different from them by the wing venation as written in the Discussion. The male genitalia (Figs 5, 5a) are similar to those of Leurogyia peristictum Common, 1965, but can be distinguished by the rather narrow uncus, with sub-acute apex; the stick-shaped hami with broadened apex; the rather rounded valva, curved at middle of ventral margin with a subtriangular lobe medially. Aedeagus nearly straight with bifid apex, cornuti absent. The female genitalia (Fig. 6) are in general similar to those of allied genera, but are characteristic especially by the sclerotized ductus bursae near the entrance, and the signum with a bundle of spines, and the accessory sac originating from the head of the signum.
Distribution. The genus occurs only in Korea.
Etymology. The species name of the new genus is derived from the common name for “moth” in Korea (Nabang).
Nabangana koreana sp. nov.
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 R4 and R5 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 R4 and R5 are positioned together near the apex at the costa.
Etymology. The species name is derived from the type locality (Korea).
