Circobotys unicolor Wang, sp. nov. (Figs 7, 14, 21) Diagnosis. This species is superficially similar to C. aurealis (Leech, 1889) in female, but can be differentiated by the sacculus with a small triangular dorso-medial process, the short triangular editum, and the phallus without spines in the male genitalia; the sclerite in the ductus bursae without dentations anteriorly, and the signum rounded on the anterior margin in the female genitalia. In C. aurealis, the sacculus has a finger-shaped dorsal process, the editum is slender triangular, and the phallus has three to four spines; the sclerite of the ductus bursae has dentations anteriorly, and the signum is flat on the anterior margin. Description. Adult (Fig. 7) wingspan 23.0–25.0 mm. Vertex and frons yellow or buff, frons with white or yellowish white stripe laterally. Labial palpus with first segment buff; second and third segments yellow to buff. Maxillary palpus yellow to buff. Antenna yellow, scape and basal flagellomeres white on anterior margin. Tegula and thorax yellow to buff dorsally, grayish white ventrally. Abdomen yellow to buff on dorsal surface, grayish white on ventral surface. Forewing triangular, relatively small compared with other species; costal margin straight except slightly arched before apex; apex rounded; termen bluntly arched, shorter than length of dorsal margin; dorsal margin almost straight; uniformly orange, deeper along costa margin, termen and dorsal margin; cilia yellow to buff. Hindwing gray tinged with yellow; cilia buff. Ventral surface of wings concolorous with dorsal surface. Male genitalia (Fig. 14). Uncus broad basally, gradually narrowed to 5/6, distal 1/6 sharply narrowed to a point. Valva broad, only slightly narrower at base, bluntly rounded at apex; costa straight, narrowed from base to pointed tip, reaching distal 1/5 of costal valva apically; ventral margin arched; sacculus widely protruded dorsally, with a small triangular dorsomedial process. Editum small, triangular; sella spine-like, slightly curved, extending ventrad to sacculus. Juxta with median indentation anteriorly, broadly concave posteriorly, lateral lobes narrowed to pointed tip. Phallus short and thick, shorter than valva; cornutus spine-like. Female genitalia (Fig. 21). Apophyses anteriores approximately 1.7 times as long as apophyses posterioreis. Ductus bursae with broad sclerite throughout posterior half, dilated anterior to sclerite, sclerite with fine carina along anterior 2/3. Signum blunt at both ends of transversal median ridge, posterior margin medially produced to a small process, anterior margin rounded. Material examined. Holotype ♂, Zhubalong, Batang County (29º47′N, 99º06′E; elev. 2500 m), Sichuan, 10 July 2001, coll. Houhun Li and Xinpu Wang, genitalia slide No. GQ11237. Paratypes. 12♂ 11♀, 10–11 July 2001, other same as holotype; 1♂ 1♀, Xiangcheng County (28º56′N, 99º48′E; elev. 2800 m), Sichuan, 13 July 2001, coll. Houhun Li and Xinpu Wang. Distribution. China (Sichuan). Etymology. The specific name is from the Latin unicolor, referring to the uniformly colored wings.
