Diagnosis. Barsine andromeda ( Figs 13–16 ) resembles externally B. perpallida ( Figs 5–7 ), but can be easily distinguished by its blackish antennae (ochreous yellow in B. perpallida ), much darker, yellow body and forewing coloration, and black basal part of the forewing costa. The male genitalia of B. andromeda ( Figs 40, 41 ) are similar to those of B. yuennanensis ( Figs 42, 43 ) and B. eurydice ( Fig. 44 ), but differ from B. yuennanensis in distally broadened uncus, much broader juxta, narrower medial costal process having a strongly curved outer margin and directed ventrally (it is directed ventro-distally in B. yuennanensis ), slightly more robust basal saccular process, slightly narrower distal saccular process, broadly conical membranous 1 st medial diverticulum (hook-like curved and granulated in B. yuennanensis ), the presence of two subdiverticula of the 2 nd medial diverticulum (in B. yuennanensis there is only one subdiverticulum of the 2 nd medial diverticulum), the presence of only granulation on 2 nd medial diverticulum (in B. yuennanensis the 2 nd medial diverticulum has an elongated cluster of short but robust cornuti of various size), and longer distal section of the 3 rd medial diverticulum. Compared to those of B. eurydice , the male genitalia of B. andromeda have distally broadened uncus (in B. eurydice it has a uniform width and is slightly curved distally), much broader juxta, narrower medial costal process, distally broader basal saccular process, narrower distal saccular process, broadly conical and membranous 1 st medial diverticulum (hook-like curved and granulated in B. eurydice ), two subdiverticula of the 2 nd medial diverticulum (in B. eurydice there is only one subdiverticulum of the 2 nd medial diverticulum), granulation only on the 2 nd medial diverticulum (in B. eurydice the 2 nd medial diverticulum has an elongated cluster of small short cornuti of various size), and longer distal section of the 3 rd medial diverticulum. The female genitalia of B. andromeda ( Fig. 52 ) differ from those of B. yuennanensis ( Fig. 53 ) in its broader ostium bursae, broader posterior section of ductus bursae, more rugose posterior sclerotized section of corpus bursae, and longer appendix bursae. Compared to those of B. eurydice ( Fig. 54 ), the female genitalia of B. andromeda have broader anterior and posterior ends of ductus bursae, and slightly larger appendix bursae.

Description. Adult ( Figs 13–16 ). Forewing length 19.5–20.0 mm in males (19.5 mm in holotype) and 20.0 mm in females. Antennae blackish, male antennae ciliate, female antennae filiform. Body and forewing ground color dark yellow. Pattern absent. Forewing costa black basally and subbasally. Hindwing pale yellow. Male genitalia ( Figs 40, 41 ). Uncus narrow, laterally flattened, broadened distally, with claw-like tip. Tuba analis broad, membranous, subscaphium broad and setose. Tegumen short and narrow. Juxta large, broad, X-shaped. Vinculum short, more or less V-shaped. Valva broad basally, strongly narrowed distally. Medial costal process narrow, trigonal, with curved outer margin, directed ventrally. Distal costal process absent. Distal membranous lobe of valva narrow, short, directed distally. Sacculus broad, its basal process long, robust, curved dorsally, and pointed apically. Distal saccular process bilobate, its dorsal lobe short, blunt, directed dorsally-distally; distal lobe of distal saccular process elongated, with blunt apex, directed distally. Aedeagus slightly curved medially and broadened distally. Basal diverticulum of vesica short, broad, globular, membranous. 1 st medial diverticulum broadly conical with rounded apex, membranous. 2 nd medial diverticulum elongated, narrow, granulated, with one medial and one basal short diverticula. 3 rd medial diverticulum broadened basally, its distal section elongated, and narrowed, its inner surface granulated, while outer surface covered with short but robust cornuti of various size. 4 th medial diverticulum short, broad, covered with short but robust cornuti of various size. 5 th medial diverticulum short, broad, globular, covered with short but robust cornuti of various size. Basal plate of vesica ejaculatorius large and heavily sclerotized, broadly trigonal with slightly curved outer margin. Female genitalia ( Fig. 52 ). Papillae anales broad, trapezoidal with rounded corners, setose. Apophyses long and thin, of equal length. Ostium bursae broad. Ductus bursae sclerotized, elongated, dorso-ventrally flattened, slightly broadened anteriorly and posteriorly, its posterior part with several broad longitudinal subostial folds. Corpus bursae short, globular, its anterior half membranous. Posterior half of corpus bursae with one elliptical signum with medial groove, and sclerotized, rugose area surrounded by area of weak, shortly spinulose scobination. Appendix bursae sclerotized, short, curved, with broad base, situated postero-laterally.

Etymology. In the ancient Greek mythology, Andromeda was the daughter of the Aethiopian king Cepheus and his wife Cassiopeia, famous for her beauty. The species name refers to its pure and beautiful delicate wings. Noun in apposition.

Distribution. Central and South West China (Shaanxi, Hubei and Sichuan Provinces).
