Diagnosis. Externally, B. rawanga sp. nov. is very similar to B. incompletostriga sp. nov., and differs only in the slightly shorter and more rounded forewing apex. The male genitalia differ from those of B. incompletostriga sp. nov. in the distally much broader valva, absence of a medial costal process, the trigonal distal costal process (whereas in B. incompletostriga sp. nov. it is bilobate), the much smaller membranous apical lobe of valva, the weaker distal saccular process, the narrower aedeagus, and in the vesica structure. The female genitalia of B. rawanga sp. nov. differ from those of B. incompletostriga sp. nov. in the different shape of antrum having broad lateral lobes, the much longer ductus bursae, the narrower band-like cluster of shorter and more robust spines in the posterior section of corpus bursae, presence of a large elliptic cluster of short robust spines in the medial section of corpus bursae, and the stronger dentate signum.

Description. Adult ( Figs. 20–21 ). Forewing length 10–10.5 mm in males and 11–11.5 mm in females. Antennae of both sexes ciliate. Head and thorax red, abdomen dark brown. Forewing broad, with rounded apex and 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 narrow, shield-like, weakly sclerotized; transtilla narrow, weakly granulate; valva elongated, distally broadened; costa moderately sclerotized, distally broadened, with short irregular dentation subapically and claw-like distal process directed distally; medial costal process absent; distal membranous lobe of valva short, trigonal, apically rounded; sacculus narrow, strongly setose, with robust, claw-like distal process. Aedeagus long, narrow, straight; vesica elliptic, curved dorsally, with one small membranous ventral subbasal diverticulum, three small membranous medial diverticula, one broad latero-medial diverticulum with broad dense cluster of short robust spines, large apical diverticulum with medial cluster of granulation and transverse apical row of several short, robust, trigonal cornuti of different size. Female genitalia ( Fig. 45 ). Ovipositor moderately broad, conical; apophyses anteriores and posteriores long and thin, apophyses anteriores shorter than posteriores; antrum broad, with folded dorsal margin and large, heavily sclerotized, rounded lateral folds; ductus bursae long, dorso-ventrally flattened, anteriorly slightly broadened, well sclerotized, with weakly sclerotized lateral margins; corpus bursae globular, its posterior section with long, narrow, sclerotized cluster of short and robust spines of different size; medial section of corpus bursae with broad, elliptic cluster of small robust spines of different size dorsally, and round sclerotized plate with diffuse margins dorsally; anterior section of corpus bursae membranous, with heart-like, weakly dentate signum; appendix bursae membranous, short and broad, rounded, situated latero-posteriorly.

Distribution. Northern Myanmar (= Burma).

Etymology. The species is named after the Rawang people inhabiting far northern Kachin State of Myanmar, the type locality of the species.
