Diagnosis. Forewing length is 12–14 mm in males and 14–15.5 mm in females. Barsine gloriosa can be separated from other relatives by its not wavy antemedial line and not enlarged connection of antemedial and medial transverse lines of forewing (that is also not enlarged in B. kanchenjunga only). The male genital capsule of B. gloriosa differs from that of B. dejeani by its shorter and more curved uncus, longer tegumen being straight, the presence of a dentate plate of manica, narrower valva, less developed medial costal process, smaller distal costal process directed distally, smaller distal membranous lobe of valva, the absence of a basal lobe of sacculus, and trigonal, narrower and more prominent distal saccular process. The aedeagus of B. gloriosa is longer and less curved than that of B. dejeani . The vesica of B. gloriosa differs from that of B. dejeani by its unilobate and weakly granulated subbasal diverticulum, dorsal medial diverticulum bearing granulation and a narrow cluster of small but robust cornuti, smaller ventral medial diverticulum with smaller cornuti, smaller distal diverticulum being membranous, and smaller basal plate of vesica ejaculatorius. In the female genitalia, the antrum is broad, with a deep and narrow medial concavity (whereas in B. inflexa and B. gloriosa that is narrow and caliciform), the ductus bursae is long (that is much shorter in B. inflexa and B. gloriosa ), the corpus bursae is large and bears spinulose scobination.

Remarks. 1. Holloway (2001) has restored gloriosa to a valid species. However, the male specimen from NE India dissected by Holloway (slide BMNH(E) Arct.-5273) is not conspecific to the holotype and belongs to B. garo Volynkin, 2018 . 2. There is a slight variation in the female genitalia structure: compared to those of the holotype female from Khasi Hills ( Fig. 48 ), in the Myanmar population the antrum has a slightly deeper medial concavity, and the posterior section of ductus bursae is slightly broader ( Fig. 49 ). However, male genitalia of both populations show no differences.

Distribution. North East India (Meghalaya, Sikkim, Assam, Manipur, Arunachal Pradesh) ( Moore 1878; Arora & Chaudhuri 1982, as cruciata ; Chaudhuri 2003, as cruciata ; Singh et al. 2005; 2014, as cruciata ) and North Myanmar (Kachin State).
