description: The Barsine inflexa species-group
Diagnosis. The species-group is related to the B. cuneonotatus species-group (Figs 54–57), but its male genitalia differ clearly by the uncus being swollen and broadened basally (that is evenly narrow in the cuneonotatus group) broad tegumen, broad and blunt distal costal process (that is small and thorn-shaped in the cuneonotatus group), the reduced distal membranous lobe of valva (in the cuneonotatus group, that is well separated, large and its dorsal part is sclerotized), the very small or reduced medial costal process (that is large in the cuneonotatus group), the distal saccular process being short and broad or reduced (in the cuneonotatus group, that is long and robust), and the narrower and curved aedeagus (while in the cuneonotatus group, the aedeagus is straight and broader). In the female genitalia, the ductus bursae is narrow with strongly broadened, caliciform antrum and the small appendix bursae directed posteriorly, whereas in the cuneonotatus group the ductus bursae is evenly broad without a developed antrum, and the appendix bursae is large and directed anteriorly.
Description. External morphology of adults. Small moths with forewing length 10.5–14.5 mm in males and 12.5–15.5 mm in females. The sexual dimorphism is expressed only in the larger size of females. Antennae of both sexes ciliate, with longer cilia in males. Body coloration and forewing ground color from orange to brick red. Forewing pattern consists of narrow blackish brown transverse lines, yellow stripes along veins and short blackish brown stripes on veins in submarginal area. Antemedial line V-like angled in cell; medial line S-like curved and connected to antemedial line in cell; postmedial line V-like curved, often W-like wavy opposite cell. Costal and anal wing margins edged with blackish brown. Cilia blackish brown. Hindwing ground color from pale ochreous to pale red. Cilia as ground color. Slight brownish suffusion often present at apex. Male genitalia. Uncus robust, broadened and swollen basally (up to discoid in B. inflexa), curved, apically pointed. Tuba analis moderately broad; scaphium narrow, very weakly sclerotized; subscaphium as small setose area. Tegumen shorter than valva, strongly broadened. Juxta weakly or moderately sclerotized, shield- or X-shaped. Vinculum as long as tegumen or shorter, robust, U-shaped. Valva elongated, usually slightly broadened distally, its costa slightly curved medially, with small or very small process directed distally. Distal membranous lobe of valva reduced, broad and very short. Sacculus narrow (only in B. dejeani with large basal setose lobe), in some species (B. dejeani, B. gloriosa and B. thagyamin) bears a small medial process. Distal saccular process short, broadened and blunted. Aedeagus narrow, curved. Vesica narrow, with several diverticula: one subbasal, one-two medial and one-two distal ones, which may bear clusters of granulation or numerous small cornuti or short spinules. Basal plate of vesica ejaculatorius small, narrow. Female genitalia. Ovipositor short and broad. Papillae anales large, rectangular with rounded corners. Apophyses long and thin; apophyses posteriores two times longer than apophyses posteriores. Ostium bursae broad. Ductus bursae sclerotized, dorso-ventrally flattened, elongated, with well-developed caliciform antrum. Corpus bursae sack-like, with spinulose scobination. Appendix bursae small, conical, membranous, situated postero-laterally.
