Diagnosis. Forewing length is 13–14 mm in males and 13.5–14.5 mm in females. This and next two species form the species complex with similar external appearance characterized by the yellow wing coloration and similar genitalia structure. Barsine prominens differs from B. wernerthomasi by its significantly smaller size and longer blackish marginal stripes on veins of hindwings; in comparison to the recently described B. paraprominens , it differs by the smaller size, the medial line being not connected to the antemedial line in the cell, and the antemedial line angled in the cell and interrupted. The male genitalia of B. prominens differ from those of B. wernerthomasi by the distally narrower valva with slightly shorter distal section between apical costal process and valva apex, the more robust medial costal process, the slightly longer and curved distal costal process, the distal saccular process being shorter and thicker apically, the presence of robust cornuti in the distal diverticulum of vesica (while in B. wernerthomasi the distal diverticulum has a cluster of cornuti), and stronger granulation of lateral diverticula of vesica. The male genitalia of B. prominens differ from those of B. paraprominens by the valva being narrower distally, the medial costal process being narrower medially and slightly curved (that is straight in B. paraprominens ), and the slightly shorter distal saccular process. In the female genitalia, B. prominens differs from B. wernerthomasi by the much smaller and weaker sclerotized posterior sclerotized area of corpus bursae, and the much stronger spinulose scobination of corpus bursae.

Distribution. East Nepal, North-East India (Volynkin 2018) and Myanmar. The record for China (Tibet) ( Fang 2000) most probably belongs to B. subzebrina or B. pluma .
