Diagnosis. Externally, the species is similar to B. pseudocardinalis sp. nov., also distributed in North Thailand, but can be separated by its smaller size and much narrower forewings of both sexes. The male genitalia of the new species differ clearly from those of B. pseudocardinalis sp. nov. in the distally broader valva, absence of a medial costal process, the basally setose sacculus with a well separated tooth-like distal process, and the vesica configuration. The female genitalia differ from those of B. pseudocardinalis sp. nov. in presence of a band-like cluster of robust spines in the posterior section of corpus bursae, and a large and strongly dentate signum in the anterior section of corpus bursae.
Description. Adult (Figs. 18–19). Forewing length 8.5–9.5 mm in males and 11–12 mm in females. Antennae of both sexes ciliate. Head and thorax red, abdomen dark brown. Forewing elongated and narrow, with rounded apex and anal angle. Ground color of forewing red, pattern consists of a narrow longitudinal trigonal black strip along vein Cu which is distally broadened and reaching wing margin between M1 and M2. Cilia red, with black strip situated from connection with dark longitudinal strip to veins Cu1. 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 shieldlike, weakly sclerotized; transtilla broad; valva elongated, with almost parallel margins; costa moderately sclerotized, with short trigonal distal process directed distally; medial costal process small, trigonal, apically narrowed; distal membranous lobe of valva broad, rounded; sacculus broad, weakly setose, with reduced distal process. Aedeagus broad, straight; vesica broad, with one subbasal membranous diverticulum, two short subbasal diverticula with bunches of two-three spines of different size surrounded by several small robust trigonal cornuti, broad distal elongated diverticulum with rounded sclerotized cluster of numerous small robust trigonal cornuti, and long tubular medial diverticulum with bunch of two large spine-like cornuti. Female genitalia (Fig. 45). Ovipositor short, broadly conical; apophyses anteriores and posteriores long and thin, apophyses anteriores slightly longer than posteriores; antrum broad, with elongated 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 band-like cluster of robust spines of different size; anterior section of corpus bursae membranous, with large, trigonal, heavily sclerotized and strongly dentate signum; appendix bursae membranous, short and broad, rounded, situated latero-posteriorly.
Distribution. North Thailand (Chiang Mai, Phayao, Nan and Lampang provinces).
Etymology. Nang Kwak is a feminine spirit of household in Thai folklore that brings good fortune and prosperity. She is represented as a beautiful woman wearing a red dress.
