description: <i>Circobotys albimarginata</i> Wang, sp. nov. (Figs 5–6, 13, 20) Diagnosis. This species is similar to <i>C. cryptica</i> Munroe &amp; Mutuura, 1969 superficially, but can be differentiated by the valva nearly parallel sided dorso-ventrally, the dorsal process of the sacculus longer than wide, the sella with the subrectangular basal part not produced to a sharp process, and the cornutus spine-like in the male genitalia. In <i>C. cryptica</i>, the ventral margin of the valva is arched, the dorsal process of the sacculus is wider than long, the sella has a slightly broad base that protrudes to before the end of the sacculus and forms a sharp process, and the cornutus is absent. Description. Male adult (Fig. 5) wingspan 31.0–36.0 mm. Vertex and frons pale yellowish brown or deep yellowish brown, frons with white stripe laterally. Labial palpus with first segment white; second segment fuscous except somewhat white at base; third segment fuscous or pale brown. Maxillary palpus brown. Antenna fuscous or pale brown, scape white on anterior margin. Tegula and thorax fuscous, thorax with fine setae ventrally. Forewing narrowly elongate; costal margin straight; apex curved downward, somewhat hook-shaped with fuscous cilia; termen obliquely truncate, longer than length of dorsal margin; dorsal margin arched basally, shallowly concave distally. Ground color brown or pale yellowish brown, patterns fuscous: antemedian line from basal 1/6 of costal margin to basal 2/5 of dorsal margin; orbicular stigma faint, extremely faint in some specimens; distal discoidal stigma somewhat crescent; postmedian line from distal 1/4 of costal margin oblique to basal 1/3 of Ml, then incurved to middle of CuA 1, transversely to base of CuA 2, finally to basal 3/5 of dorsal margin through basal 1/3 of 1A. Hindwing broad, triangular, brown or pale brown, area covered by forewing yellowish white; postmedian line fuscous, from middle of M 1 incurved to junction of 1A and 2A. Cilia of wings brown except median 1/3 buff. Wings paler on ventral surface. Female adult (Fig. 6) wingspan 29.0–32.0 mm. Vertex and frons brown. Labial palpus with third segment brown. Maxillary palpus brown with paler apex. Antenna pale brown, scape and basal flagellomeres white on anterior margin. Thorax without fine setae ventrally. Forewing broad; costal margin straight; apex slightly curved downward; termen obliquely inward, shorter than length of dorsal margin; dorsal margin slightly arched. Ground color pale yellowish brown, deepening from base to apex, patterns blackish brown: antemedian line from basal 1/4 of costal margin oblique to basal 2/5 of dorsal margin; orbicular stigma rounded, small, invisible in some individuals; postmedian line from basal 2/3 of costal margin oblique to middle of Ml, then incurved to basal 1/3 of CuA 2 through basal 1/4 of CuA 1, finally straight to basal 1/3 of dorsal margin. Hindwing with postmedian line from basal 2/3 of M 1 to middle of CuA 2, arched outward. Cilia of wings buff except forewing black at apex. Male genitalia (Fig. 13). Uncus broad at base, gradually narrowed to basal 3/5, distal 2/5 extremely narrow, tapering to sharp apex. Valva nearly parallel sided dorso-ventrally, length about 3 times maximum width, distal 1/6 slightly narrowed to obtuse apex; costa straight, almost reaching end of costal valva; sacculus produced semicircularly and arched dorsally, with a finger-shaped dorsal process. Editum spine-like, reaching beyond dorsal process of sacculus; sella sub-rectangular basally, hook-shaped distally; small sharp process set between sella and editum at base, sometimes invisible. Juxta formed by two reniform lobes connected basally. Phallus slightly longer than valva, almost straight; cornutus spine-like, about 1/5 length of phallus. Female genitalia (Fig. 20). Apophyses anteriores about 2 times as long as apophyses posteriores. Ostium bursae surrounded by thin sclerite. Antrum short, somewhat funnel-shaped. Ductus bursae with sclerite throughout posterior 3/5, this sclerite serrate on right side along posterior 1/3, edged with dentations along anterior 1/3 on outer sides; ductus seminalis arising from ductus bursae posteriorly. Signum with a median transversal carina sharply protruded on both ends. Material examined. Holotype &amp;male;, Daozhen County (29º09′N, 107º25′E; elev. 1300 m), Guizhou, 20 August 2004, coll.

China (Guangxi, Guizhou, Henan, Hunan, Jiangxi, Zhejiang). Etymology. The specific name is from the Latin <i>albus</i>, meaning white, and <i>marginatus</i>, meaning margin, referring to the white posterior margin of each abdominal segment dorsally. Remarks. The male and female adults of this species vary obviously. Females have broader and more opaque wings, but the male and female genitalia of specimens collected from different areas show no significant variation.
