Diagnosis. Forewing length 18.0–19.0 mm in males and 19.0–19.5 mm in females. Barsine ruficollis ( Figs 31, 32 ) is similar externally to B. eurydice ( Figs 29, 30 ), but can be easily distinguished by its slightly smaller size, pale yellow body and forewing coloration (ochreous yellow in B. eurydice ), and the presence of a red subbasal subcostal stroke on forewing (absent in B. eurydice ). Male genital capsule of B. ruficollis ( Fig. 45 ) is most similar to that of B. yuennanensis ( Figs 42, 43 ), but differs in its uncus being strongly broadened subapically, smaller medial costal process, and distal saccular process having narrower base. The vesica of B. ruficollis differs clearly from that of B. yuennanensis in the absence of a basal diverticulum, much broader and rounded 1 st medial diverticulum (narrower and hook-like curved in B. yuennanensis ), much broader and shorter 2 nd medial diverticulum having no subdiverticulum, narrower cluster of cornuti of the 3 rd medial diverticulum, shorter and granulated 4 th medial diverticulum (bearing cornuti in B. yuennanensis ), much larger 5 th medial diverticulum, and larger 6 th medial diverticulum. In the female genitalia, B. ruficollis ( Fig. 56 ) differs from B. yuennanensis ( Fig. 53 ) in longer ductus bursae being narrower anteriorly and having longer longitudinal subostial folds, much broader and more rugose posterior sclerotized area of corpus bursae, and smaller signum. Compared to those of B. eurydice ( Fig. 55 ), the female genitalia of B. ruficollis have significantly longer ductus bursae, less rugose posterior sclerotized area of corpus bursae, and smaller signum.

Distribution. China (Yunnan) ( FANG 1991, 2000).
