Diagnosis. This species is similar in appearance to C. epicompsa Meyrick, 1922 ( Clarke 1963: 134) , but can be distinguished by the sacculus with basal 2/3 rectangular and the cornutus being a long sclerotized rod with a triangular process at basal 2/5.

Description. Adult ( Fig. 3 View FIGURES 1 – 4 ). Wingspan 21.5–31.0 mm. Head brown mixed with white. Antenna with scape pale brown, pecten white, flagellum white dorsally and yellowish brown ventrally. Labial palpus creamy white, scattered with blackish-brown scales, denser on dorsal surface of first and second segments; third segment white, with a fuscous ring near apex. Thorax and tegula blackish brown, mixed with sparse brown and white scales. Forewing ground color pale greyish brown to deep greyish brown; costal margin with an orange-yellow quadrangular spot beyond 1/3 and a narrow ochreous stripe from about 2/3 extending to subapex; rectangular pale yellow spot at base along fold, white-edged with scales on both anterior and posterior margins, and with two tufts of raised reddish-brown scales on distal margin, the one above fold larger than the one below fold; discal and plical stigmata of raised ochreous-brown scales, not distinctively separated; elongate triangular blackish discocellular patch narrowed from near base to apex below costa; large irregular blackish patch between the two tufts and discal stigma as well as beyond outer margin of discal stigma, the former broad anteriorly, narrowed posteriorly, surrounded by white lines, the latter narrowed medially, edged with white lines except on posterior margin; outer cellular patch finely dusted with creamy yellow and greyish brown scales, greyish fulvous along veins; termen blackish brown, with discontinuous white line along inner margin; fringe greyish brown, blackish brown subbasally. Hind wing pale brown; fringe yellowish grey, pale ochreous near base. Abdomen dark fuscous, edged with rufous band at each segment on posterior margin, preceded by bands of whitish bristles; anal tuft fulvous. Legs fuscous, mottled light brown and white; fore tibia creamy white dorsally, tarsus mixed with creamy white; hind tibia with loose pale yellow hairlike scales, scattered with fuscous scales on outer surface, tarsus light brown, edged with fuscous ring on end of each segment.

Male genitalia ( Fig. 7 View FIGURES 5 – 8 ). Uncus a little shorter than gnathos. Gnathos with distal 1/5 beak-shaped. Valva with costa concave beyond middle. Cucullus elongate and triangular, with apex narrowly rounded. Sacculus with basal 2/3 semirectangular, widening distally and folded dorsally; length of apical lobe about 2/5 width of cucullus at base. Juxta about 1/3 length of phallus, with two thin rods laterally. Phallus curved, basal 3/5 tubular, distal 2/5 somewhat fusiform, apex slightly pointed; cornutus strongly developed into a long sclerotized rod, length about 2/ 5 that of phallus, basal half slightly broader, apex acute, with a triangular process at basal 2/5.

Female unknown.

Biology. Adults were found from June to August. Immature stages are unknown.

Distribution. China (Fujian, Guangdong, Taiwan).

Etymology. The specific name is derived from the Latin prefix longus- = long, and the Latin word clavatus = baculiform, in reference to the cornutus strongly developed into a long sclerotized rod.
