Diagnosis. Forewing length is 10–11.5 mm in males and 11 mm in females. Externally, B. navneetsinghi  is very similar to large specimens of the sympatric B. subzebrina  , and can be separated by the genitalia structures only. The male genitalia of B. navneetsinghi  differ clearly from those of B. subzebrina  by its larger vinculum, the absence of a medial process of juxta, much narrower and curved medial costal process, much shorter distal costal process directed distally, stronger dentation of the ventral margin of sacculus, apically pointed distal saccular process, and larger, spine-like cornuti in the largest medial diverticulum of vesica. The male genitalia of B. navneetsinghi  are most similar to those of B. radians  , but differs clearly by their narrower, curved and apically pointed medial costal process (that is much broader and apically rounded in B. radians  ), broader distal costal process directed distally (that is thinner, apically pointed and directed dorsally in B. radians  ), dentate dorsal margin of sacculus (that is setose in B. radians  ), shorter distal saccular process, and larger subbasal diverticulum of vesica. In the female genitalia, B. navneetsinghi  differs from B. radians  by its much broader, V-shaped postvaginal plate, narrower antrum, more robust spinulose scobination of corpus bursae, and much larger appendix bursae. Female genitalia of B. navneetsinghi  differ from those of B. subzebrina  by their V-shaped postvaginal plate (that is more or less T-shaped in B. subzebrina  ), heavily sclerotized margins of antrum (that has rugose membranous margins in B. subzebrina  ), much smaller signum, and significantly larger appendix bursae.

Distribution. North-East India (western Meghalaya) and North Myanmar (Kachin) ( Volynkin & Černý 2018b).
