( Figs 1 – 2 View FIGURES 1 – 4 )
Type material. Holotype: 3, China: Kuankuoshui (28º14'N, 107º12'E), Guizhou Province, 1500 m, 11.viii.2010, genitalia slide No. WJJ10023, coll. Linlin Yang; paratypes: 1 3, 12.viii.2010, 1 3, 16.viii.2010, other data same as holotype.
Diagnosis. This new species can be distinguished from its congeners by the elongate digitiform uncus, the gnathos with a tiny spinous lobe at the base of each side anteriorly, and the costa medially with a large sclerotized plate in the male genitalia.
Description. Adult ( Fig. 1 View FIGURES 1 – 4 ): Male wingspan 16.0 mm. Head whitish yellow. Labial palpus whitish yellow, acute at apex. Antenna deep yellow. Thorax, tegula and forewing pale yellow. Forewing with costa slightly arched, apex rounded, termen obliquely blunt; brown spots at middle and end of cell as well as at middle of fold, respectively; cilia grayish brown. Hindwing and cilia grey. Legs pale yellow.
Male genitalia ( Fig. 2 View FIGURES 1 – 4 ): Uncus elongate digitiform, densely covered with short hairs in distal 2/3; about as long as height of tegumen. Gnathos weak, almost membranous, medially short V-shaped, with spinous lobe at base of each side anteriorly. Valva broad basally, slightly narrowed distally, rounded apically, finely setose in distal 1/3; costa with a rectangular or elongate oval sclerite medially, along its lower edge set a comb of setae. Sacculus elongate triangular, slightly shorter than half length of valva, hooked inward apically. Saccus small, triangular, about half length of uncus. Juxta more or less heart-shaped. Phallus with basal 1/4 thin stalk-like, distal 3/4 thick; distal 3/5 with dense short spines.
Female unknown.
Distribution. China (Guizhou).
Etymology. The specific epithet is derived from the Latin word cordatus, meaning heart-shaped, referring to the shape of the juxta in the male genitalia.
