(Figs 10–12, 38, 50)

Type locality. Nepal, Annapurna Himal, 1 km NW Chitre, 2300 m, 83°41′E 28°25.5′N.

Type material. HOLOTYPE (Figs 10, 38): ♂, “ Nepal, Annapurna Himal / 1 km NW Chitre, 2300 m / 83°41’E 28°25.5’N, 23.VII.1995 / leg. Gy. M. László and G. Ronkay ”, slide MWM 37067 Volynkin (MWM / ZSM) . PARATYPES: 4 ♂♂ 1 ♀, same data as in the holotype, slides MWM 35759 (♂), MWM 35760 (♀) Volynkin (MWM / ZSM).

Diagnosis. The new species is the closest relative of B. flavicollis . Externally these two species are very similar (Figs 9–12), but B. laszloi can be distinguished by shorter lamellae of male antennae and white patagia (pale ochreous in B. flavicollis). In the male genitalia, B. laszloi (Fig. 38) differs from B. flavicollis (Fig. 37) in its smaller juxta, broader tip of medial costal process (claw-like pointed in B. flavicollis), shorter basal saccular process, broader distal saccular process, longer and narrower 1 st medial diverticulum, longer and basally granulated 2 nd medial diverticulum (membranous in B. flavicollis), much longer 3 rd medial diverticulum with more numerous cornuti, and smaller 5 th medial diverticulum. The male genitalia of B. laszloi differ from those of B. hololeuca (Fig. 36) in their narrower valva, longer and narrower basal saccular process, their longer and slightly narrower distal saccular process, broader 1 st medial diverticulum, stronger cornuti on 3 rd medial diverticulum, narrower base of the 3 rd medial diverticulum, and the presence of only granulation at base of the 3 rd medial diverticulum (in B. hololeuca there is a broad cluster of short robust cornuti at base of the 3 rd medial diverticulum). The females of B. flavicollis and B. hololeuca are unknown therefore the female genitalia of B. laszloi (Fig. 50) can be compared only with the externally similar, but not closely related species B. perpallida (Fig. 49), from which B. laszloi differs in slightly broader and much shorter ductus bursae with shorter longitudinal subostial folds, and the presence of shortly spinulose scobination in the medial section of corpus bursae.

Description. Adult (Figs 10–12). Forewing length is 15.0–15.5 mm in males (15.5 mm in holotype) and 17.0 mm in female. Male antennae shortly bipectinate, female antennae filiform. Body and ground color of both wings pure white. Basal half of forewing costa blackish. Male genitalia (Fig. 38). Uncus narrow, laterally flattened, dorso-ventrally curved, apically pointed. Tuba analis broad, membranous, subscaphium broad and setose. Tegumen moderately broad, shorter than valva. Juxta short, X-shaped, with short medial dorsal protrusion. Vinculum short, U-like. Valva elongated, slightly narrowed distally. Medial costal process short, apically blunt, its outer margin curved. Distal costal process short, tubercle-like. Distal membranous lobe of valva moderately broad, elongated, apically rounded, directed distally. Sacculus broad basally and strongly narrowed medially and distally, its basal process short, narrowly trigonal, slightly curved dorsally. Distal saccular process short, broadly trigonal with blunt apex, reaches the valva apex. Aedeagus straight, moderately broad. Medial section of vesica with area of weak granulation at base of 3 rd medial diverticulum; 1 st medial diverticulum of vesica broad, globular, membranous; 2 nd medial diverticulum narrow, elongated, finger-shaped, weakly granulated; 3 rd medial diverticulum elongated, covered with numerous short but robust cornuti of various size; 4 th medial diverticulum short, broad, covered with small short cornuti; 5 th medial diverticulum broad, globular, its outer surface with cluster of numerous short but robust cornuti of various size. Basal plate of vesica ejaculatorius narrow, elliptical. Female genitalia (Fig. 50). Papillae anales broad, trapezoidal with rounded corners, setose. Apophyses long and thin, apophyses anteriores slightly shorter than apophyses posteriores. Ostium bursae broad. Ductus bursae broad, short, dorso-ventrally flattened, its posterior half with several narrow longitudinal subostial folds. Corpus bursae ovoid, its anterior third membranous; posterior section of corpus bursae weakly sclerotized; medial section of corpus bursae weakly sclerotized, with weak, shortly spinulose scobination and one small, narrow signum. Appendix bursae large, moderately sclerotized, situated postero-laterally, its base broad, its distal section elongated, narrowly conical.

Etymology. The species is dedicated to Dr. Gyula M. László (Leominster, UK), the collector of the type series and the senior author’s friend.

Distribution. Barsine laszloi is to date known only from its type locality, Annapurna mountain massif in northern Central Nepal.
