Type material.

China, Hainan: Holotype ♂, Yinggezui (19.05N, 109.56E), Yinggeling, 599 m, 30.VII.2017, leg. X Bai et al., slide No. ZXJ19011. Paratype: 1♂, Mt. Wuzhi, 732 m, 4.VIII.2017, leg. X Bai et al.

Diagnosis.

The new species can be distinguished from its congeners by having the apex of the valva curved dorsally at almost a right angle, a sub-ovate process extending from beyond the sacculus of the valva, and a large vinculum extended to a broadly rounded anterior margin.

Description.

Adult (Fig. 4 View Figures 4–11 ). Wingspan 8.0-10.0 mm. Head yellow, vertex mixed with black. Labial palpus yellow; second segment with distal 2/3 mixed with black scales, forming a black ring at apex; third segment mixed with black scales from middle to before apex on dorsal surface. Antenna yellow; flagellum alternated with black on dorsal surface except several basal flagellomeres yellow. Thorax yellow; tegula black basally, yellow distally. Forewing yellow, with black scales; costal margin with basal 1/4 black, diffused to above fold posteriorly; costal spot black, sub-triangular, from between basal 2/5 and 2/3 extending crossing anterior margin of cell posteriorly; apical patch black, running from distal part of costal margin along termen; tornal spot black, ill-defined; distal and plical spots black, ovate; black dot at anterior angle of cell distinct; fringe yellow, tinged with blackish brown. Hindwing and fringe grey. Legs yellow, with exception on ventral surface: foreleg mixed with black scales on femur and tibia, first tarsomere of tarsus with a black dot, apical three tarsomeres black; midleg with femur black apically, tibia black except yellow apically, tarsus black except yellow at apices of basal two tarsomeres; hindleg with scattered black scales.

Male genitalia (Fig. 20 View Figures 20–27 ). Uncus slightly wide at base, narrowed from base to pointed apex. Tegumen widened medially; lateral arm slightly narrowed anteriorly. Valva wide at base, slightly narrowed from base to before basal 2/3, curved upward at ca. distal 1/3 almost at a right angle, obtusely rounded at apex; ventral margin heavily sclerotized, forming a wide band reaching ca. distal 1/3, with a large sub-ovate process beyond sacculus; costa wide, with sparse setae; transtilla short, narrowed to pointed apex. Sacculus sub-triangular, relatively small, heavily sclerotized on margins, with sparse long setae on dorsal surface. Vinculum extended anteriorly, broadly rounded on anterior margin. Juxta slender, arched in U-shape (attached to apex of phallus). Phallus slender, strongly curved medially, more than twice length of valva, heavily sclerotized distally, with a fusiform sclerite.

Female

unknown.

Distribution.

Hainan (Mt. Wuzhi, Yinggeling).

Etymology.

The specific epithet is derived from the Latin apic - (adj., apical) and curvatus (adj., curved), referring to the valva curved dorsally at almost a right angle in the male genitalia.
