description: Genus Dusungwua Kemal, Kizildağ & Koçak, 2020
Dusungwua Kemal, Kizildağ & Koçak, 2020: 1.
Furcata Du, Sung & Wu, 2005: 99. Junior homonym of Furcata Werby, 1938.
Type species: Rhodophaea dichromella Ragonot, 1893.
Generic characters. Adult with vertex flat. Antenna filiform, flagellum with fine cilia ventrally; male flagellum usually simple, with basal segments slightly constricted and incurved, or strongly constricted into arched shape in some species. Ocellus present; chaetosema well-developed. Labial palpus upturned. Maxillary palpus tiny, fanshaped at tip. Proboscis well-developed. Forewing without ridge of raised scales; antemedial line usually with a large black spot posteriorly on its inner side; with 11 veins (Fig. 2): R 2 free, from upper edge; R 3+4 and R 5 stalked in basal half, from upper angle of cell; M 2 and M 3 separated, M 3 from lower angle of cell; CuA 1 and CuA 2 free; cell about 3/5 length of forewing. Hindwing with 10 veins (Fig. 2): Sc approximated to Rs in basal 2/5; M 1 and Rs shortly stalked, from upper angle of cell; M 2 and M 3 shortly stalked or approximated in basal 1/5 to1/2, both from lower angle of cell; CuA 1 and CuA 2 free; cell about 1/2 length of hindwing.
Male genitalia (Figs 13 ̅22). Uncus variously shaped, subtriangular, or bell-shaped, or trapezoidal. Gnathos clubbed, slightly bifid apically, in some species constricted at middle, enlarged in distal half. Transtilla well developed, produced in a U or V shape, and forming a pair of postero-lateral lobes. Valva narrow; clasper undeveloped, usually papillary; costa shorter than valva; sacculus shorter than half length of valva. Juxta U-shaped or V-shaped, lateral lobes stout. Vinculum U-shaped or V-shaped, sometimes with lateral sides incurved anteriorly. Phallus with flocculent crimples. Culcita five bunches, inner pair with slim scales and reed-like, outer pair with broad scales, petal-like, middle bunch respectively consisting of cup-like, triangular and style-shaped scales.
Female genitalia (Figs 23 ̅31). Papillae anales broad, rounded at apex. Apophyses anteriores and posteriores short and subequal. Eighth segment broad and short. Antrum flat, sclerotized weakly. Ductus bursae and corpus bursae membranous, granulated on inner surface. Signum present or absent, usually invaginated and consisting of several granules. Ductus seminalis usually from posterior margin of corpus bursae, seldom from ductus bursae.
Diagnosis. This genus is similar to Eurhodope H̹bner, 1825, but can be recognized by the male genitalia with the transtilla extending postero-laterally to form a pair of lateral lobes, which is not in the latter.
Distribution. China, Japan and Korea. The distribution of this genus in China is shown in Fig. 1.
