Diagnosis.

This species is distinguished by wings with postmedial line dentate and excurved between M 2 and CuA 2 (Fig. 6 ); gnathos vestigial to a narrow band (Fig. 12 a ); valva with distal 1 / 3 narrowed gradually and pointed apically, costa arched medially and bearing a cluster of long setae (Fig. 12 ); fibula a triangular lamina, with setae medially (Fig. 12 b ); phallus posteriorly with a finger-like protruding sclerite, a thick, spine-like cornutus and a brush-like cornutus (Fig. 12 c ).

Redescription.

Habitus (Fig. 6 ). Forewing length 8.0–15.0 mm, wingspan 25.0–33.0 mm. Frons and vertex yellowish brown. Labial palpus with 1 st segment yellowish white ventrally, the remainder yellowish brown. Maxillary palpus brown. Antenna yellowish brown, with ventral cilia ~ 1 / 3 in length of diameter of flagellomere in male. Patagium and tegula yellow, with brown patches. Thorax yellow dorsally, white ventrally. Legs yellowish white, distal end of front tibia black. Wings yellow, with purple-brown lines and patches. Forewing with three small spots at base, another spot near basal dorsum; antemedial line slightly wavy, accompanied by a large elliptical pale patch inside; orbicular stigma a dark brown dot; discoidal stigma reniform, yellow centrally; postmedial line obliquely inward from costa, dentate and excurved between M 2 and CuA 2, then incurved to discoidal stigma below and sinuous to inner margin; an irregular large patch between anterior postmedial line and terminal margin, another irregular large patch below discoidal stigma and extended to tornus; a line of small spots along terminal margin. Hindwing with discoidal stigma a short oblique stripe; postmedial line same as forewing before CuA 2, not apparent afterwards; an irregular large patch near apex beyond anterior postmedial line; a misty band below discoidal stigma, accompanied by another irregular misty wide band extended to tornus. Abdomen yellow dorsally; 1 st and 2 nd tergites with pale black spots laterally; 7 th tergites black posteriorly in male; terminally black in some female individuals.

Male genitalia (Fig. 12 ). Uncus semicircular. Gnathos vestigial to a narrow band (Fig. 12 a ). Valva with distal 1 / 3 narrowed gradually, and pointed apically; costa arched medially and bearing a cluster of long setae. Fibula a triangular lamina, with setae medially (Fig. 12 b ). Saccus oval. Juxta a broad plate, invaginated anteriorly. Phallus posteriorly with a finger-like protruding sclerite, with a thick spine-like cornutus and a brush-like cornutus composed of a spine cluster (Fig. 12 c ).

Female genitalia (Fig. 13 ). Apophyses anteriores ~ 2 × length of apophyses posteriores. Ostium bursae relatively large, antrum broad. Ductus bursae ~ 2 × length of corpus bursae. Corpus bursae nearly rounded, with a round signum.
