Diagnosis.

This species is similar to P. obfuscalis in appearance and genitalia, but can be distinguished by the body color paler than the latter (Fig. 10 ); uncus short and broad triangular (Fig. 17 a ); valva shorter and broader than the latter, with distal 1 / 3 narrowed very gradually and rounded apically (Fig. 17 ). In P. obfuscalis , the uncus is semicircular (Fig. 12 a ); the distal 1 / 3 of the valva is narrowed gradually and pointed apically (Fig. 12 ).

Description.

Habitus (Fig. 10 ). Forewing length 11.0–13.5 mm, wingspan 24.0–30.0 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. Thorax yellow dorsally, white ventrally. Legs yellowish white, distal end of front tibia black. Wings pale 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 slightly 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 near apex beyond anterior postmedial line, another misty patch near tornus below CuA 2; a line of spots along marginal line. 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 band below discoidal stigma, accompanied by another irregular misty wide band extended to tornus. Cilia of fore and hind wings yellowish white. Abdomen yellow dorsally, white ventrally; 1 st and 2 nd tergites with pale black spots laterally and 7 th tergites black posteriorly in male.

Male genitalia (Fig. 17 ). Uncus short and broad triangular. Gnathos vestigial to a narrow band and bearing a few short setae (Fig. 17 a ). Valva broad tongue-shaped, with distal 1 / 3 narrowed very gradually, and rounded apically; costa arched medially and bearing a cluster of long setae; fibula a short lamina, setose basally (Fig. 17 b ). Saccus oval. Juxta a broad plate. Phallus posteriorly with a finger-like protruding sclerite, with a thick, needle-like cornutus and a brush-like cornutus composed of a spine cluster (Fig. 17 c ).

Female genitalia (Fig. 18 ). Apophyses anteriores ~ 2 × length of apophyses posteriores. Antrum broad, ductus seminalis originating from antrum. Ductus bursae ~ 2 × length of corpus bursae. Corpus bursae nearly oval, with a round signum.

Distribution.

China (Chongqing, Guizhou, Yunnan, Hainan, Hubei, Zhejiang).

Etymology.

The species name lurida is derived from the Latin word luridus, an adjective, meaning pale yellow, indicating the pale wing color.
