Paratypes: CHINA: Hainan Province: 3 ♂, Datian Conservation Zone (19°42΄N, 109°47΄E), 25 m, 1.xii.2009, leg. Zhaohui Du & LinlinYang, genitalia slide Nos. YLL10095; YLL10029, YLL10030; 1 ♂, Mt. Yingge, 21.vi.2010, leg. Bingbing Hu & Jing Zhang, genitalia slide No. YLL11012.

Diagnosis. This new species can be recognized by the uncus lobe expanded distally, with a narrowed band between two lobes at base; the short, trapezoidal valva dentate on costal margin in the male genitalia.

Description. Adult ( Fig. 47 View FIGURES 44 − 51 ). Wingspan 13.0−17.0 mm in male. Vertex dusty yellow, frons pale orange yellow. Antenna 0.9× length of forewing; scape dusty yellow, mixed with darker scales above, with a few black pecten bristles; flagellum unicolorous, yellowish white. Labial palpus pale yellow on inner surface, dark brown except yellowish brown at apex of third segment on outer surface. Thorax and tegula yellowish brown or dark brown. Forewing index 0.29, yellowish brown, dark brown along costa in basal 1/3; retinaculum present; cilia yellowish brown, without cilia line. Hindwing grayish brown, with a single short, slender evenly curved frenular bristle; cilia grayish brown. Fore and mid legs blackish brown; hind leg yellowish brown.

Pregenital abdomen. In male, first tergum with sclerotization almost filling whole frame; coremata present in eighth segment; eighth sternite 0.2× as long as wide, slightly concave on posterior margin, without caudal process; eighth tergite rectangular, without caudal process.

Male genitalia ( Fig. 76 View FIGURES 76 − 79 ). Vinculum slightly convex on anterior margin, straight on posterior margin; medial process absent from ventrocaudal margin. Tegumen posterior margin convex, 0.7× depth of vinculum. Uncus with broad skirt-like base that interrupted by traces of uncus lobes; uncus lobe 0.8× depth of vinculum, digitate, not twisted, gently bent dorsad, basal half narrowed, distal half slightly expanded, apex rounded; with a narrow band between two lobes at base. Valva short, somewhat trapezoidal, narrowed at base, broadened to apex; costal margin dentate, dentations strong basally, weak distally; basal flange absent; ventral margin convex distally, forming large ventral lobe; basal margin with small, triangular ‘secondary apodeme’ close to ventral margin; apical margin slightly concave, with minute dentations; inner surface unmodified. Juxta angled caudally, short, about 0.5× length of aedeagus. Aedeagus slightly longer than valva, tubular, apex complete and rounded ventrally, deeply concave dorsally. Bulbus ejaculatorius 2.0× length of aedeagus, subdistal section narrowed, distal section expanded.

Female unknown.

Distribution. China (Hainan).

Etymology. The specific name is derived from the Latin dentatus, meaning dentate, referring to the dentate costal margin of the valva.
