Externally, the new species ( Figs. 9–10 ) resembles B. nubifascia ( Figs. 5–8 ) and B. contrastata sp. nov. ( Figs. 13–14 ), but differs from the first by the more contrast forewing patter and slightly paler hindwings, and from the latter by the significantly more diffuse pattern. The male genitalia ( Fig. 35 ) is close to those of B. nubifascia ( Fig. 34 ), but differ by presence of a short ventral subbasal lobe of the costal process, the much more robust ventral costal process, the broader and shorter distal saccular process, presence of only large thorn on aedeagus carinal plate, a smaller number of cornuti in the subbasal ventral diverticulum, the much smaller lateral cornuti, and presence of a long distal cornutus. The female genitalia ( Fig. 49 ) is similar to those of B. nubifascia ( Fig. 48 ) and B. obscura sp. nov. ( Fig. 50 ), but differ from B. nubifascia by the shorter ductus bursae, posteriorly broader and having stronger lateral sclerotized folds, and the much smaller lateral sclerotized lobes of the corpus bursae; from B. obscura sp. nov. it differs by the ductus bursae much broader anteriorly and having much larger and stronger sclerotized lateral folds, and the lateral sclerotized lobes of corpus bursae significantly larger and bearing longer spinules on inner surface. Description. Adult ( Figs. 9–10 ). Forewing length 15–15.5 mm in males and 16–17 mm in females. Male antennae bipectinate, female antennae ciliate. Head and thorax ochreous-yellow; abdomen paler, ochreous. Forewing ground color intensive ochreous-yellow. Forewing pattern consists of subbasal black dot, curved antemedial line consisting of four blackish dots, S-like medial and postmedial lines situated very close to each other and consisting of blackish small spots of different size, and cuneate wedge connected to shadows in the subterminal area. Cilia ochreous-yellow. Hindwing monotonous pale ochreous-yellow, cilia pale ochreous-yellow. Male genitalia ( Fig. 35 ). Uncus long, narrow, smoothly curved, apically pointed. Tuba analis narrow, scaphium narrow, weakly sclerotized; tegumen moderately long and broad, slightly C-like curved; juxta trigonal, with deep lower concave; vinculum short, broad, U-like. Valva elongated, broad; costa heavily sclerotized, with robust, curved and apically pointed ventral process, and large robust distal process consisting of large trigonal distal lobe and small basal lobe directed ventrally; sacculus broad, with long and claw-like curved distal process. Aedeagus long and narrow, with short and narrow coecum, and carinal plate with one large thorn. Vesica membranous, globular, with short subbasal ventral diverticulum with two-three thorn-like cornuti, conical medial ventral diverticulum, apical field of cornuti of different size, lateral field of medium-sized cornuti, and long needle-like subapical cornutus; basal plate of ductus ejaculatorius small, weakly sclerotized. Female genitalia ( Fig. 49 ). Ovipositor short, broad, conical; papillae anales broad, rectangular with rounded edges; apophyses and posteriores long and thin, apophyses posteriores about two times longer than apophyses anteriores. Antevaginal plate wrinkly sclerotized, with deep round concave near its conjunction with ostium bursae. Ostium bursae broad; ductus bursae broad, short, narrowed anteriorly, dorso-ventrally flattened, with strongly sclerotized lateral folds, left fold longer and broader than right fold. Corpus bursae very small, subdivided into two large asymmetric heavily sclerotized lateral lobes covered inside with numerous short spinules, and elliptical, weakly sclerotized anterior section with weak spine-like scobination; appendix bursae small, conical, membranous, situated dorso-posteriorly. Distribution. The species is known from SW China ( Sichuan , Yunnan ); reported for Lijiang, Yunnan ("Likiang") as Asura nubifascia by Daniel (1952) . Etymology. 'Clandestinus' is 'hidden' in Latin, the species name refers to its confusion with B. nubifascia .
