Barsine subzebrina Volynkin & Černý, 2018 , Zootaxa, 4402 (2): 341, figs 6–12, 31–34, 43 (Type locality: “ Nepal, Annapurna Himal, valley of Kali Gandaki, 1300 m, near Tatopani”).

Type material examined. Holotype ( Figs 7 , 153 ): ♂, Nepal, Annapurna Himal, valley of Kali Gandaki, 1300 m, near Tatopani, 83°39’E, 28°29’N, 20.VI.1996, leg. Gy. M. László & G. Ronkay, slide MWM 33545 Volynkin (Coll. MWM/ ZSM); Paratypes: 76 ♂ and 28 ♀ from Nepal, India and Myanmar listed by Volynkin & Černý (2018b) (Colls MWM/ ZSM, CKC) .

Diagnosis. The species significantly varies in size (forewing length is 9–11 mm in males and 10–12 mm in females). B. subzebrina has no significant external differences from its closest relative B. zebrina and can be separated from it by the genitalia structures. The male genitalia of B. subzebrina are similar to those of B. zebrina , but differ by the larger medial costal process, narrower distal costal process with much longer apico-lateral projection, narrower basal lobe of sacculus with evenly curved dorsal margin armed with larger dens, whereas in B. zebrina the medial costal process is smaller, the distal costal process is broader and has much smaller or absent apico-lateral projection, the basal lobe of sacculus is larger, trigonal, armed with smaller dens. The female genitalia of the two species are very similar, but in B. subzebrina the postvaginal plate is narrower, V-like, and the antrum has a deep concavity, whereas in B. zebrina the postvaginal plate is significantly broader, more or less T-like, and the antrum has no concavity.

Distribution. Bhutan ( Hampson 1900, as zebrina ), Central and Eeast Nepal, NE India (Sikkim, Meghalaya), North Myanmar (Kachin) ( Volynkin & Černý 2018b).
