( Figs. 4 View FIGURES 1 – 4 , 8 View FIGURES 5 – 8 )
Type material. Holotype 3, CHINA: Bubang, Mengla (21°17ʹ N, 101°20ʹ E), Yunnan Province, 650 m, 25.viii.2005, coll. Yingdang Ren, genitalia slide No. ZL08017 ( NKUM).
Diagnosis. This species is similar in appearance to C. demotarcha ( Meyrick, 1907) ( Clarke 1963: 134) and C. grandipennata Moriuti, 1985 ( Moriuti 1985: 11) , but can be separated from them by the forewing having a larger discocellular stigma and the hindwing purplish grey. In C. demotarcha the discocellular stigma is absent, and the hindwing is yellowish white; in C. grandipennata the discocellular stigma is smaller, and the hindwing is pale grey. This new species also differs from other known species by the phallus with a strong semicircular dorsal process arising from between basal 1/4 and 1/ 2 in the male genitalia.
Description. Adult ( Fig. 4 View FIGURES 1 – 4 ). Wingspan 45.0 mm. Head yellowish white. Antenna with scape creamy-white except basal half brown on dorsal surface, pecten creamy; flagellum creamy-white and brown alternately. Thorax and tegula whitish yellow, basally mixed with brown scales. Forewing ground color whitish yellow, scattered with pale fulvous, brown and fuscous scales; discal and plical stigmata smaller, elliptic, fuscous with black scales in middle; discocellular stigma large, oval, black; about eight obscure black spots ranging from distal 1/6 of costal margin and along termen to tornus fuscous, accompanied by smaller white spots on their inner margin; fringe greyish brown except black basally, greyish yellow on tornus. Hindwing purplish grey, glossy; cell with an indistinct greyish brown patch near end; fringe pale ochreous except greyish brown along dorsum, with a fuscous subbasal line and a pale grey subapical shade. Legs predominantly creamy white, mottled with brown and fuscous scales; fore tibia strongly dilated in distal half, with long pale ochreous fluffy scales, tip black; median tibia moderately dilated by closely appressed scales; post tibia fuscous mixed with black, with long black hairlike scales distally. Abdomen brown, posterior margin of each segment fuscous, edged with whitish yellow hairs; anal tuft whitish yellow.
Male genitalia ( Fig. 8 View FIGURES 5 – 8 ). Uncus shorter than gnathos, distal 2/5 narrowed, posterior margin truncate. Gnathos dorsally protruded beyond middle, distal half narrowed to about 1/4, distal 1/4 abruptly narrowed and duck-billed. Cucullus suboval, narrowly pointed at apex. Sacculus long, length 1.5 times that of cucullus, gradually narrowed, dorsal margin obliquely straight; apical lobe broad, about 2/3 width of cucullus, densely setose ventrally. Phallus with distal 3/5 gradually narrowed to thin and hooked apex, with a strong semicircular dorsal process arising from between basal 1/4 and 1/2, covered with warts, marginally dentate.
Female unknown.
Biology. Adults were found in August. Immature stages are unknown.
Distribution. China (Yunnan).
Etymology. The specific name is derived from the Latin aduncatus = hooked, in reference to the hooked apex of the phallus.
