Type material. CHINA: Yunnan Province: Holotype ♂, Mt. Weibao (24.52°N, 98.84°E), Weishan County, 2244 m, 21.VII.2013, coll. Shurong Liu, Yuqi Wang and Kaijian Teng, genitalia slide No. TKJ17276.

Paratypes (1♂, 1♀): 1♂, Mt. Weibao , Dali, 2205 m, 3.VIII.2014, coll. Kaijian Teng et al., genitalia slide No. TKJ17437 ; 1♀, Mt. Weibao , Weishan County, 2200 m, 20.VII.2001, coll. Houhun Li and Xinpu Wang, genitalia slide No. TKJ17280 .

Diagnosis. Hypatopa weibaoshana is similar to H. huayingshana in the male genitalia, but it can be separated from the latter by the costal process of the valva being strongly angled outward beyond the middle on the outer margin, and the juxta not concave medially on the posterior margin. In H. huayingshana the costal process of the valva is acutely angled before the middle on the outer margin, and the juxta is deeply concavely U-shaped medially on the posterior margin.

Description. Forewing length 7.0–8.0 mm ( Fig. 4 ). Head brown, scales tipped with grayish white, often becoming pale yellow. Antenna with scape brown on dorsal surface except some scales tipped with grayish white, grayish white on ventral surface; pecten brown; flagellum with dorsal surface dark brown and becoming paler from base to apex, ventral surface grayish white and ciliated in male. Labial palpus with outer surface dark brown except some scales tipped with grayish white, inner surface grayish white mixed with pale gray scales; third segment slightly shorter than second, grayish white apically. Haustellum brown. Thorax and tegula dark brown, scales tipped with grayish white. Forewing grayish brown, scales tipped with grayish white, intermixed with some dark brown scales; costa with a dark brown obtriangular spot at basal 1/3, extending to upper margin of cell; discal, two discocellular and plical spots dark brown; plical spot touching inner margin of discal spot anteriorly, widened to dorsum posteriorly; marginal spots dark brown, ill-defined; fringe pale brown, intermixed with grayish white tipped dark brown scales. Hindwing and fringe grayish brown, gradually darker from base to apex. Legs with dorsal surface grayish white; ventral surface dark brown, some scales tipped with grayish white; tibia of hindleg and all tarsomeres grayish white at apex.

Male genitalia ( Fig. 12 ). Uncus subtriangular, wide at base, narrowed to a rounded apex, keeled ventrally on distal half; slightly curved ventrad, sparsely setose. Gnathos with posterior margin slightly arched and notched medially. Dorsal part of valva with costal process narrowed medially, obtusely angled outward beyond middle on outer margin, then slightly narrowed to rounded apex, from costa widened ventrad to proximal flange; proximal flange ovoid, with sparse spines along ventral and outer margins, its inner surface with dense microtrichiae on dorsal half and with setae on ventral half. Ventral part of valva with basal 2/3 broad, suboval; distal process clubbed, bent in- ward, sparsely setose on outer surface, flat and smooth on inner surface; sacculus wide at base, gradually narrowed to terminal, with sparse long setae along distal 4/5 of ventral margin. Juxta a transverse band, broadened medially. Vinculum a narrow band. Phallus slightly shorter than valva, wide at base, slightly narrowed to basal 1/3, almost uniform medially, distal 1/3 gradually narrowed to blunt apex; internal sclerite curved ventrad at distal 1/3; anellus with basal half bearing cone-like setae.

Female genitalia ( Fig. 20 ). Apophyses posteriores approximately 3 times length of apophyses anteriores. Eighth tergum with a darkly pigmented longitudinal median streak. Intersegmental membrane posterior to seventh segment bearing microtrichiae around ostium. Seventh tergum straight on posterior margin, sternum slightly concave medially on posterior margin. Ductus bursae nearly as long as corpus bursae; internal wall with overlapping platelets on anterior 2/5 and becoming denser anteriorly; ductus seminalis arising from posterior 1/6 of ductus bursae. Corpus bursae ovate; signum at posterior 2/5 of corpus bursae, triangular, with a subtriangular process arising from its anterior margin.

Distribution. China (Yunnan).

Etymology. The specific epithet of this species is derived from the type locality, Mt. Weibao (= Weibaoshan).
