Diagnosis. Forewing length is 10–11.5 mm in males and 11 mm in females. Externally, B. navneetsinghi  sp. nov. ( Figs. 21–24View FIGURES 21–26) is very similar to large specimens of the sympatric B. subzebrina  sp. nov. ( Figs. 6–12View FIGURES 1–12), and can be separated by the genitalia structures. The male genitalia of B. navneetsinghi  sp. nov. ( Figs. 39, 40View FIGURES 39–41) are surprisingly different from those of B. subzebrina  sp. nov. ( Figs. 31–34View FIGURES 31–34) by absence of medial process of juxta, larger vinculum, much narrower and curved medial costal process, much shorter distal costal process directed distally, stronger dentation of ventral margin of sacculus, apically pointed distal saccular process, and larger, spinelike cornuti in the largest medial diverticulum of vesica. In the male genitalia, B. navneetsinghi  sp. nov. ( Figs. 39, 40View FIGURES 39–41) is closer to B. radians  ( Figs. 25, 26View FIGURES 21–26, 41View FIGURES 39–41, 47View FIGURES 42–47) due to pentagonal juxta without medial process, large vinculum, and spine-like cornuti in vesica, but differs clearly by the narrower, curved and apically pointed medial costal process, broader distal costal process directed distally, dentate dorsal margin of sacculus, shorter distal saccular process, and larger subbasal diverticulum of vesica, whereas in B. radians  ( Fig. 41View FIGURES 39–41) the medial costal process is much broader and apically rounded, the distal costal process is thinner, apically pointed, directed dorsally, the dorsal margin of sacculus is setose, the distal saccular process is longer, and the subbasal diverticulum of vesica is significantly smaller. The female genitalia of B. navneetsinghi  sp. nov. ( Fig. 46View FIGURES 42–47) differ from those of B. radians  ( Fig. 47View FIGURES 42–47) by the much broader, V-shaped postvaginal plate, broader ostium bursae, narrower sclerotized posterior section of ductus bursae, more robust spinulose scobination of corpus bursae, and much larger appendix bursae; from B. subzebrina  sp. nov. ( Fig. 43View FIGURES 42–47) differ by the V-shaped postvaginal plate (whereas in B. subzebrina  sp. nov. the postvaginal plate is more or less T-shaped), heavily sclerotized margins of ostium bursae and posterior section of ductus bursae (whereas in B. subzebrina  sp. nov. the ostium bursae has rugose membranous margins, and the ductus bursae is evenly membranous), much smaller signum, and significantly larger appendix bursae.

Distribution. B. navneetsinghi  is known from northeastern India (W Meghalaya) and northern Myanmar (Kachin State).

Etymology. The species name is dedicated to Dr. Navneet Singh, a famous researcher of the Arctiinae  of India.
