Diagnosis. Forewing length 16.5–19.0 mm in males and 17.0–21.0 mm in females. Male of B. nigrovena ( Fig. 23 View Figs 17–24 ) can be easily distinguished from other congeners by the presence of broad blackish shades in postmedial and submarginal areas of both wings. Female of B. nigrovena ( Fig. 24 View Figs 17–24 ) is similar to that of the striped form of B. yuennanensis ( Fig. 22 View Figs 17–24 ), but differs clearly in its broader forewing, bright yellow forewing ground colour (pale yellow in B. yuennanensis ) with broader blackish suffusion along veins and blackish cilia of both wings. The male genitalia of B. nigrovena ( Fig. 43 View Figs 42–44 ) are similar to those of B. yuennanensis ( Fig. 42 View Figs 42–44 ), but differ in distally narrower uncus, shorter and basally broader juxta, larger vinculum being more or less V-like (smaller and U-like in B. yuennanensis ), broader medial costal process directed ventrally (in B. yuennanensis it is narrower and directed ventrally-distally), slightly larger distal costal process, slightly shorter 2 nd medial diverticulum bearing smaller cornuti, narrow and more prominent subdiverticulum of the 2 nd medial diverticulum, and slightly narrower tip of the 3 rd medial diverticulum. The male genitalia of B. nigrovena are also similar to those of B. eurydice ( Fig. 44 View Figs 42–44 ), but can be distinguished by their weaker uncus, shorter and slightly broader juxta, basally narrower valva, slightly larger distal costal process, slightly narrower distal membranous lobe of valva, slightly longer distal lobe of the distal saccular process, smaller basal diverticulum of vesica, slightly shorter 2 nd medial diverticulum with slightly larger subdiverticulum, and the tip of the 3 rd medial diverticulum bearing small cornuti (it is granulated in B. eurydice ). In the female genitalia, B. nigrovena ( Fig. 54 View Figs 54–57 ) differs from B. yuennanensis ( Fig. 53 View Figs 48–53 ) in ductus bursae being less broadened anteriorly, and larger and more heavily sclerotized signum. Compared to those of B. eurydice ( Fig. 55 View Figs 54–57 ), the female genitalia of B. nigrovena have narrower sclerotized posterior area of corpus bursae and more heavily sclerotized signum.
