Diagnosis. This species is similar to the type species P. xeropis both in appearance and in genitalia. It can be distinguished by the labial palpus without a banding pattern, and the sub-rectangular symmetrical lateral parts of the uncus. In P. xeropis , the labial palpus has a greyish brown banding pattern, and the digitate lateral parts of the uncus are asymmetrical ( Clarke, 1969: 313. Figs 1–1 d).

Redescription. Adult ( Fig. 2 a) with wingspan 10.0–12.0 mm. Head shiny creamy white to yellowish white, with sparse brown scales above compound eyes. Antenna about 5/6 length of forewing, with scape creamy white and glossy; flagellum pale yellow and black alternately. Labial palpus creamy white; second segment with compact scale tuft on ventral surface; third segment fuscous near apex on outer side. Thorax and tegula creamy white. Forewing yellowish brown, mixed with black and white scales; three sub-ovate blackish spots equidistantly placed at basal 1/3 of cell on upper margin, at both middle and end of cell respectively, surrounded by creamy white; obscure black spot at apex of wing sometimes; fold with dense creamy white scales, with black spots at basal 1/3, at middle and at distal 1/3 respectively, sometimes obscure; fringe pale brown. Hindwing greyish brown; fringe pale brown, two to three times of wing width. Legs dominantly yellowish white; fore- and midlegs with coxae and femora blackish brown basally on ventral surface, with tibiae and tarsi blackish brown on outer surface; midleg with tibia and tarsus mixed with greyish brown scales on outer surface, tarsus with yellowish white ring at apex of each tarsomere; hindleg with tibia bearing long yellowish brown hairs, tarsus blackish brown at base of each tarsomere on outside.

Male genitalia ( Fig. 3 a): Uncus wide, sub-rectangular, lobes separated from anterior 1/4, narrowed at base, slightly widened toward posterior margin, posterior margin with triangular concavity at middle, forming an inner process truncate at apex, an outer process rounded at apex with dense setae laterally. Gnathos nearly as long as uncus, widened basally, slightly narrowed distally, indented at apex ( Fig. 3 a1); culcitula sub-round. Tegumen divided from basal 1/3; lateral branch equally wide, truncate anteriorly. Valva apically reaching top of uncus; ventral margin sinuate, concave at basal 1/3 and distal 1/3, bluntly protruded medially; dorsal margin slightly concave before rounded apex. Aedeagus slightly thinned to blunt apex.

Female genitalia ( Fig. 4 a): Papillae anales more or less digitate, with setae. Apophyses anteriores about 2/5 length of apophyses posteriores. Ostium bursae rounded, with a semicircular plate anteriorly. Ductus bursae membranous, longer than corpus bursae, with a wide sclerotized ring between basal 1/5 and 1/4. Corpus bursae ovate, membranous; signum triangular, with finely serrate edge.

Host plant: Poaceae : Oryza sativa L. ( Li & Chen 1988).

Distribution. China (Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Henan, Hunan, Yunnan), India.
