Description. Adult ( Figs 1, 4 ) with wingspan 15.0–22.0 mm. Vertex in male brown, back head white, with long blackish brown scales along inner margin of compound eye; in female yellowish brown. Antennae in male with scape blackish brown on dorsal surface, yellowish white on ventral surface, length about 2 times of its width; flagellae yellowish white on dorsal surface, yellowish brown on ventral surface, sinus with scales greyish black dorsally, yellowish white ventrally; female antennae filiform, yellowish white. Labial palpi in male with first and second segments yellowish brown, second segment stout, appressed to face and upturned to vertex, distal 1/3 white on inner side, third segment grey, porrect; labial palpi in female yellowish brown on outer side, yellowish white on inner side, third segment length equal to second one. Patagium, tegulae and thorax greyish brown, sometimes suffused with red scales. Forewing elongate, blackish brown, tinged with yellowish brown scales between fold and dorsum; antemedial line yellowish white, sinuate, extending from basal 1/3 of costal margin to middle of dorsum, fading in anterior 1/3, incurved at vein A and lower margin of cell; discal spot indistinct; postmedial line yellowish brown, from distal 1/6 of costal margin to distal 1/5 of dorsum, incurved at vein M 1 and A; fringe greyish brown. Hindwing yellowish white, brown near costal margin and termen; fringe white; underside with black scales along upper margin of cell and at base of dorsum. Abdomen brown on dorsal surface, in male basal four segments with black scales ( Fig. 4 ). Legs greyish brown to reddish brown; tarsi black each segment fading distally; inner spurs 1.8 times length of outer spurs.

Male genitalia ( Fig. 5 ). Uncus trapezoidal, length about 2.7 times of its width on posterior margin; posterior margin straight; lateral margin folded, densely setose dorsally. Gnathos about 2/3 length of uncus. Transtilla with basal half wide, distal half narrower and digitate. Valva narrow and elongate, basal 2/5 wide, nearly triangular, distal 3/5 gradually narrowed, densely setose; clasper located at basal 2/5 of valva near costa, nearly rectangular, sparely setose distally; costa narrow, reaching end of valva; sacculus nearly triangular, about 2/5 length of valva, with long bristles on ventral margin. Juxta tongue-shaped, lateral arms papillary. Vinculum U-shaped, anterior margin slightly concave at middle. Aedeagus cylindrical, 1.4 times length of valva, distal 2/3 with sclerotized wrinkles and granules; cornutus one, curved, spine-like, placed at distal part of aedeagus. Culcita four pairs.

Female genitalia ( Fig. 7 ). Papillae anales triangular, length about 1.7 times of width at base, densely setose. Eighth abdominal segment with length equal to width, anterior and posterior margin concave medially. Apophyses posterior 1.3 times length of apophyses anterior. Antrum wide, funnel-shaped, anterior 1/4 with longitudinal wrinkles. Ductus bursae short, about 3/10 length of corpus bursae, anterior half sclerotized. Corpus bursae long ovate, membranous, length about 3 times of width, constricted at middle, encircled with a band, gradually narrower from the constriction and covered with long spines. Ductus seminalis originating from posterior part of corpus bursae.

Diagnosis. This species is similar to P. hypolepidota Turner, 1905 in morphology, but can be distinguished from the latter by the scape of antennae in male without a spindle-shaped process, the uncus straight on the posterior margin and the rectangular clasper in the male genitalia, as well as the corpus bursae not coiled in the female genitalia. In P. hypolepidota , the scape of antennae in male has a spindle-shaped process; the uncus is deeply concave at middle on the posterior margin, and the clasper is elongate digitate in the male genitalia; and the distal half of the corpus bursae is coiled in the female genitalia.

Distribution. China (Hainan).

Etymology. The specific name is derived from Latin rectus, meaning straight, referring to the straight posterior margin of uncus in the new species.
