Genus Prabadra Dubatolov, Volynkin, N. Singh, Joshi & Černý View in CoL , gen. nov.

Type species: Prabadra occidentalis sp. nov.

Diagnosis. The new genus is closely similar to the genera Zadadra and Chinasa . Adults ( Figs 3–6 View FIGURES 1–10 ) are externally similar to those of Chinasa ( Figs 7, 8 View FIGURES 1–10 ). The sexual dimorphism is limited than in Zadadra ( Figs 11–18 View FIGURES 11–18 ) due to the less modified forewing shape and venation of male. The male genital capsule of the new genus ( Figs 23–25 View FIGURES 23–26 ) is similar to that of Zadadra ( Figs 27–32 View FIGURES 27–30 View FIGURES 31–32 ), but in Prabadra gen. nov. the intervalval commissura is longer, the sacculus is less prominent ventrally, the distal saccular process is club-shaped and its distal dilated section is heavily setose (an autapomorphic feature).Additionally, the cucullus of Prabadra gen. nov. is dilated, with a ventral plate covering the distal saccular process outwardly (an autapomorphic feature), whereas the cucullus and the distal saccular process of Zadadra are well-separated from each other. The aedeagus vesica of Prabadra gen. nov. bears a stick-like cornutus, whereas in Zadadra , cornutus is absent. Compared to Chinasa ( Fig. 26 View FIGURES 23–26 ), the male genital capsule of Prabadra gen. nov. is characterized by the shorter intervalval commissura, the dilated cucullus having a ventral plate covering the club-shaped distal saccular process outwardly (whereas in Chinasa , the cucullus is tapered distally and rounded apically and well-separated from the blade-shaped distal saccular process). The aedeagus vesica of Prabadra gen. nov. bears a stick-like cornutus, whereas the vesica of Chinasa lacks cornuti. The female genitalia of the new genus ( Fig. 34 View FIGURES 33–38 ) are very similar to those of Chinasa ( Fig. 35 View FIGURES 33–38 ) and Zadadra ( Fig. 37, 38 View FIGURES 33–38 ) but the sclerotized pockets of the 7 th sternite of Prabadra gen. nov. are large, triangular and connected to each other, whereas in Chinasa , such structure is absent and in Zadadra , they are smaller, rounded and far apart from each other.

Description. Adult. Forewing length 9.5– 10 mm in males and 12 mm in females. Male antenna ciliate, female antenna filiform. Sexual dimorphism moderate: male ( Figs 3–5 View FIGURES 1–10 ) has less elongate forewing with nearly straight costa and rounded apex, whereas, female ( Fig. 6 View FIGURES 1–10 ) has forewing with costa slightly convex post-medially and apex pointed. Male forewing cell with elongate narrow area of androconial scales along the vein R. Forewing ochreous brown with paler costal margin, diffuse brown apical streak and dark brown postmedial costal spot. Hindwing monotonous brownish grey. Male genitalia ( Figs 23–25 View FIGURES 23–26 ). Uncus elongated, narrow, dorso-ventrally flattened, apically tapered. Tegumen narrow, short. Vinculum short, weak, more or less U-shaped. Valvae fused to each other in basal two thirds by intervalval commissure. Juxta narrow, somewhat broadened basally, its distal end connected to intervalval commissure by membrane. Valva wide and relatively short, its costal margin convex medially. Cucullus broad, weakly setose, with tip slightly curved dorsally and rounded ventral plate covering the distal saccular process outwardly. Sacculus moderately prominent ventrally; distal saccular process short, club-like, with heavily setose distal dilated section. Aedeagus straight, with narrow and elongate coecum; main chamber of aedeagus vesica membranous, globular, with one narrow, slightly curved, stick-like cornutus with rounded tip; vesica ejaculatorius originates from subbasal section of vesica. Female genitalia ( Fig. 34 View FIGURES 33–38 ). Papillae anales broad, trapezoidal with rounded corners. Apophyses anteriores long and thin, slightly longer than apophyses posteriores. Ostium bursae narrow, with membranous margins. Ductus bursae narrow, elongate, dorso-ventrally flattened, tapered at ostium bursae, moderately sclerotized. Corpus bursae membranous, without sclerotized elements, its posterior section narrow and tubular, anterior section broad, globular. Appendix bursae shortly conical, membranous, situated postero-laterally.
