Diagnosis. Forewing length is 10.5–11.5 mm in males and 12.5–13.5 mm in females. Barsine victoria can be separated from its closest relative B. inflexa by its slightly narrower forewing and thinner transverse lines and costal margin edge. In the male genitalia, B. victoria differs from B. inflexa by its uncus being much less broadened basally (that is discoid in B. inflexa ), much smaller distal costal process situated on the valva apex, broader medial costal process, slightly larger distal saccular process, slightly shorter aedeagus, the presence of a cluster of cornuti on the subbasal diverticulum, the presence of the ventral medial diverticulum, and smaller distal diverticulum. The female genitalia of B. victoria can be distinguished from those of B. inflexa by their weaker spinulose scobination of corpus bursae and much smaller appendix bursae.

Distribution. North East India (Meghalaya) ( Hampson 1900, as B. inflexa ) and North Myanmar (Chin and Kachin States).

Etymology. The species name refers to its type locality, vicinities of Mount Victoria in North West Myanmar.
