description: <i>Circobotys flavimarginalis</i> Wang, sp. nov. (Figs 10, 17, 23) Diagnosis. This species is similar to <i>C. plebeia</i> Munroe &amp; Mutuura, 1969 superficially, but it can be differentiated by the valva broadened medially and narrowed toward base and apex, the triangular sella produced to a sharp process before the end of the sacculus, and the strong and curved cornutus. In <i>C. plebeia</i>, the valva is subparallel dorso-ventrally, the spinelike sella is not produced to a process, and the cornuti consist of four short parallel subequal spines. Description. Adult (Fig. 10) wingspan 25.0–35.0 mm. Vertex and frons yellow to yellowish brown, frons with white stripe laterally. Labial palpus with first and second segments snowy white ventrally, dark yellowish brown dorsally; third segment dark yellowish brown. Maxillary palpus yellowish brown, paler at apex. Antenna dark grayish brown, scape and basal flagellomeres white on anterior margin. Tegula and thorax deep yellowish brown, thorax with many fine setae ventrally. Abdomen ventrally yellowish white except yellow on end; dorsally yellowish brown to dark yellowish brown, white on posterior margin of each segment. Forewing broad, sub-triangular; costal margin with basal half straight, distal half arched, dark brown basally, yellow distally; apex protruding triangularly, curved downward; termen obliquely truncate, shorter than length of dorsal margin; dorsal margin slightly arched basally. Ground color dark yellowish brown, with a narrow orange band along termen, with a stripe-shaped translucent areas between Sc and R 1 as well as between Sc and costa at base; patterns fuscous: antemedian line from basal 1/3 of 1A nearly to middle of dorsal margin; orbicular stigma extremely faint; distal discoidal stigma a short stripe, somewhat lunate; postmedian line from basal 2/3 of costal margin oblique to basal 3/5 of M 1, then incurved to basal 1/3 of CuA 2 through basal 1/3 of M 3, finally to basal 2/3 of dorsal margin through basal 2/3 of 1A. Hindwing pale brown basally, deepening toward termen, area covered by forewing yellowish white; postmedian line fuscous, from basal 3/4 of costal margin to middle of CuA 2. Cilia orange except dark brown at apex of forewing and pale brown at anal angle of hindwing. Patterns of wings distinct on ventral surface. Male genitalia (Fig. 17). Uncus broad at base, gradually narrowed to middle, distal half almost uniformly narrow, with a short apical spine. Valva broadened medially, narrowed toward base and apex, ventral margin arched, apex narrowly rounded; costa slightly concave at base, extending to 3/4 of costal valva; sacculus with a strong dorsal process at middle, its apex more or less truncate. Sella triangular, inner edge less sclerotized than outer edge, produced to a sharp process reaching before end of sacculus. Juxta nearly axe-shaped, anterior margin rounded, posterior margin concave medially. Phallus short and thick, about half length of valva, with a bundle of spines; cornutus strong, spine-like, curved, about 2/3 length of phallus. Female genitalia (Fig. 23). Apophyses anteriores approximately 2 times as long as apophyses posteriores. Antrum laterally produced backward, forming a U shape. Ductus bursae with a broad anteriorly serrated sclerite, bearing a thumbshaped process protruding from anterior end of this sclerite. Signum sharply pointed at both ends of transversal median ridge, posterior margin with a small triangular process medially, anterior margin slightly concave medially. Material examined.

Wuyi, Fujian, 22 May 2004, coll. Haili Yu; 1&amp;male;, Kuankuoshui Nature Reserves (28º14′N, 107º12′E; elev. 1500 m), Suiyang County, Guizhou, 16 August 2010, coll. Xicui Du. Distribution. China (Fujian, Guizhou, Jiangxi). Etymology. The specific name is from the Latin word <i>flavus</i>, meaning yellow, and <i>marginalis</i>, meaning margin, referring to the orange band along the termen of the forewing. Remarks. Six specimens from Fujian Province are similar to <i>C. flavimarginalis</i> Wang, <b>sp. nov.</b> morphologically, but the adult color is paler, the valva is obtuse apically and the phallus has a long strong curved cornutus but without spines in the male genitalia. They may represent a new taxon, but needing female information to confirm. In this paper, we do not include them in the type series.
