Commatarcha convoluta Li , sp. nov.

( Figs 4, 6 , 8 , 21 )

Type material. CHINA: Holotype ♀, Taiyanghe National Forest Park, Pu'er City , Yunnan Province, 1450 m, 5.iv.2015, leg. Kaijian Teng, slide No. QSN17484.

Paratypes (6 ♀): Yunnan Province: 4 ♀, 1‒5.iv.2015, other same data as holotype, slide Nos . QSN17476, QSN17477; 1 ♀, Rare Botanical Garden, Ruili City , 1000 m, 5.viii.2005, leg . Yingdang Ren. Sichuan Province: 1 ♀, Fengtongzhai , Baoxing County, 1600 m, 2.viii.2004, leg. Yingdang Ren .

Diagnosis. This species is similar to C. fanjingshana Li, 2004 in the forewing pattern. It can be differentiated in the female genitalia by the lamella postvaginalis with its anterior margin triangularly incised deeply, the narrowly elongate ostium bursae as long as or longer than 4/5 the length of the antrum, and the antrum weakly sclerotized basally. In C. fanjingshana , the lamella postvaginalis is shallowly concave on its anterior margin, the arrow-shaped ostium bursae is shorter than half length of the antrum, and the antrum is heavily sclerotized entirely.

Description. Adult ( Fig. 8 ). Wingspan 15.0‒17.0 mm. Head greyish brown, scales tipped with greyish white. Labial palpus black, extended forward; second segment with dense greyish white scales on inner surface, longer than diameter of eye; third segment short, about 1/4 length of second segment, greyish white at apex. Antenna with scape black on dorsal surface, white on ventral surface; flagellum brown, darker on basal several flagellomeres. Thorax and tegula black, with purplish blue reflection. Forewing leaden grey, mixed with black scales; costal margin straight, black, with six to seven creamy white dots almost evenly spaced from basal 1/3 to apex; apex slightly acute; termen obliquely straight, with black dots on veins; basal patch black, triangular, its outer margin with raised scales, tipped with silvery grey on anterior 1/3 and with yellowish brown on posterior 2/3; large subrectangular yellowish brown marking extending from basal 1/6 to distal 1/4, between upper margin of cell and dorsum; six scale tufts more or less along upper and lower margins of cell: tuft before upper angle of cell black, with an ocherous yellow dot on its outer side, other tufts earthy yellow mottled greyish brown, tuft at upper angle of cell edged with an ochreous yellow spot on its dorsal side; black band from middle of R3 curved to tornus; fringe black. Hindwing greyish brown, apex narrowly rounded, termen obliquely straight; fringe greyish brown.

Female genitalia ( Fig. 21 ). Papillae anales ovate, setose. Eighth sternum sub-trapezoidal, with long sparse setae on posterior margin. Apophyses anteriores about 5/8 length of apophyses posteriores. Ostium bursae narrowly elongate, approximately 4/5 length or as long as antrum; lamella postvaginalis banded, convex on posterior margin, narrowly incised triangularly on anterior margin. Antrum with basal 1/3 weakly sclerotized, becoming more sclerotized from basal 1/3 to terminal, folded by 90° at distal 1/3. Ductus bursae slender, slightly broadened toward corpus bursae, membranous, about 1.8 times length of corpus bursae, with dense granules on inner surface. Corpus bursae elongate ovate, smooth.

Male unknown.

Distribution. China: Sichuan, Yunnan.

Etymology. The specific epithet is derived from the Latin convolutus, referring to the antrum curved at distal 1/ 3 in the female genitalia.
