Barsine zebrina species-complex

Diagnosis. Members of the species-complex have the appearance common for the Barsine prominens speciesgroup. The main differences from other species of the species-group are in the male genitalia: in the B. zebrina species-complex distal costal process is robust, sacculus is well sclerotized, its dorsal surface is strongly dentate. In addition, in the majority of species juxta has a conical medial process (absent in B. navneetsinghi sp. nov.). The closest relative of the B. zebrina species-complex is B. radians (Moore, 1878) widespread in the Himalayan Region, but it is separated by its weak distal costal process and setose dorsal surface of sacculus.

Description. Adults. Small moths. Male antennae ciliate, female antennae filiform. Body creamy with admixture of numerous ochreous yellow hairs. Forewing ground color from whitish to yellowish creamy or pale yellow; pattern blackish, consists of large subbasal dot, angled and interrupted subbasal line consisting of three short strips, strongly curved, interrupted antemedial line consisting of three long strips, slightly curved medial line which can be interrupted (B. pluma, B. navneetsinghi sp. nov., B. bucseki sp. nov.) or entire (B. zebrina, B. subzebrina sp. nov.), discal spot, postmedial line strongly W-like dentate opposite the cell, and long lengthwise strokes on veins in outer part of wing; cilia creamy with black spots opposite veins. Ground color of hindwings varies from creamy white to pale yellow, with intense yellowish suffusion at anal margin; medial band thin, diffuse, slightly wavy, outer part of wing with intense blackish suffusion on veins; cilia from creamy white to pale yellow. Male genitalia. Uncus long, narrow, laterally flattened, slightly curved, apically pointed. Tuba analis broad, membranous; scaphium thin, weakly sclerotized; subscaphium as broad setose area. Tegumen short and medium broad; juxta medium broad, with large conical medial process (absent in B. navneetsinghi sp. nov.); vinculum robust, U-like. Valva long, with almost parallel margins, slightly narrowed apically; costa broad, well sclerotized; medial costal process robust, at broad base, moderately long, distally narrowed, apically tapered; distal costal process robust, dorsally directed; apical lobe of valva long and broad; sacculus well sclerotized, setose, with strongly dentate dorsal margin; distal saccular process present, varies in length and shape in different species. Aedeagus long and medium broad, slightly curved; vesica broad, globular, with medial diverticulum armed with field of small, but robust cornuti, and several small diverticula with scobination and granulation; basal plate of vesica ejaculatorius short, trigonal. Female genitalia. Papillae anales broad, rectangular with rounded edges; apophyses anteriores and posteriores of approximately equal length, long and thin. Postvaginal plate broad, V- or Tshaped; ostium bursae broad, with rugose membranous ventral margin; ductus bursae short, membranous. Corpus bursae sack-like, with dense spinulose scobination and small rounded signum with dentate surface; appendix bursae conical, curved, with dense spinulose scobination, situated latero-posteriorly.
