Diagnosis. The species significantly varies in size (forewing length is 9–11 mm in males and 10–12 mm in females). B. subzebrina sp. nov. ( Figs. 6–12 ) has no significant external differences from its closest relative B. zebrina ( Figs. 1-5 ) and can be separated from it by the genitalia structures. The male genitalia of B. subzebrina sp. nov. ( Figs. 31–34 ) are similar to those of B. zebrina ( Figs. 27–30 ), 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 sp. nov. ( Fig. 43 ) the postvaginal plate is narrower, V-like, and the ostium bursae has deep concavity, whereas in B. zebrina ( Fig. 42 ) the postvaginal plate is significantly broader, more or less T-like, and the ostium bursae has no concavity.

Distribution. The species is known from central and eastern Nepal, northeastern India (Sikkim, Meghalaya), and northern Myanmar (Kachin).
