Diagnosis. Forewing length is 10–11.5 mm in males (10 mm in the holotype) and 11.5–12.5 mm in females. The newspecies is a closest relative of B. amaculata , from which it differs externally by the pale yellowish wing coloration (that is creamy white in B. amaculata ), the longer dentation of postmedial line, and the presence of a postmedial transverse line of hindwing. The male genitalia of B. mesomene sp. n. differ from those of B. amaculata by the more robust distal costal process (that is thin, needle-like in B. amaculata ), the shorter distal section of valva, the shorter distal saccular process, the larger ventral diverticulum with strong granulation, and the presence of a medial row of cornuti in vesica. The female genitalia of B. mesomene sp. n. differ from those of B. amaculata by the narrower antrum, the larger corpus bursae and the larger appendix bursae.

Distribution. North-East India (Meghalaya), North Myanmar (Kachin), South-West China (Yunnan), North and East Thailand, Laos and Vietnam.

Etymology. Mesomene is the goddess of the waxing moon in Greek mythology.
