Diagnosis. Externally, B. incompletostriga sp. nov. is very similar to B. rawanga sp. nov., and differs only in the slightly more elongated forewing apex. The male genitalia differ from those of B. rawanga sp. nov. in the distally narrower valva, presence of the small medial costal process situated subbasally, the bilobate distal costal process, the larger membranous apical lobe of valva, the more robust distal saccular process, the broader aedeagus, and in the vesica structure. The female genitalia of B. incompletostriga sp. nov. differ from those of B. rawanga sp. nov. in the different shape of antrum without broad lateral lobes, the shorter ductus bursae, the broader band-like clusters of smaller spines in the posterior and medial sections of corpus bursae, and the less dentate signum.

Description. Adult ( Figs. 20–21 ). Forewing length 10–11.5 mm in males and 12–13 mm in females. Antennae of both sexes ciliate. Head and thorax red, abdomen dark brown. Forewing broad, with slightly elongated apex and rounded anal angle. Ground color of forewing red, with black scales on costal margin; pattern consists of a longitudinal trigonal black strip along vein Cu which is distally broadened, reaching wing margin between M1 and M2 and apically diffuse. Cilia red, without black spots. Hind wing dark brown. Male genitalia ( Fig. 33 ). Uncus long, narrow, laterally flattened, apically pointed, its distal half C-like curved. Tuba analis with weakly scobinated field in subscaphial area. Tegumen short and moderately broad; vinculum large, U-like; juxta shield-like, weakly sclerotized; transtilla broad, granulate; valva elongated, narrow, with almost parallel margins; costa heavily sclerotized, with medial dorsal fold and short but robust bilobate distal process, its dorsal lobe large, claw-like, directed dorsally, ventral lobe smaller, trigonal, directed distally; medial costal process small, trigonal, situated subbasally; distal membranous lobe of valva long, moderately broad, rounded; sacculus narrow, strongly setose, with robust, claw-like distal process. Aedeagus large, medially broadened; vesica broad, with two dorsal subbasal membranous diverticula, one medial globular diverticulum with cluster of robust granulation, one short medial globular diverticulum with bunch of robust, short, trigonal cornuti of different size, one small apical globular diverticulum with weak granulation, and one elongated apical diverticulum directed dorsally and having weak granulation basally and one or two long spine-like cornuti apically; basal plate of ductus ejaculatorius long, narrow, heavily sclerotized. Female genitalia ( Fig. 45 ). Ovipositor short, broadly conical; apophyses anteriores and posteriores long and thin, apophyses anteriores shorter than posteriores; antrum broad, with shortly dentate margin and sclerotized lateral folds; ductus bursae moderately long, dorso-ventrally flattened, anteriorly broadened, well sclerotized, with weakly sclerotized lateral margins; corpus bursae globular, its posterior section with long and broad cluster of thin and long spines of different size; medial section of corpus bursae with broad, S-like curved cluster of small spines of different size; anterior section of corpus bursae membranous, with large, heavily granulate signum; appendix bursae membranous, short and broad, rounded, situated latero-posteriorly.

Distribution. NE India (north of West Bengal, Assam, Meghalaya).

Etymology. 'Incompletostriga' means 'with an incomplete strip'. The species' name refers to absence of a black spot in its forewing cilia opposite the longitudinal black strip, for this reason the strip looks incomplete.
