Description. Imago (Fig. 4). Wingspan 9.5–10.5 mm. Head with vertex shining white, frons shining gray. Labial palpus with second segment ochreous yellow on outer surface, basal half white and distal half yellow on inner surface; third segment with basal 2/3 white, distal 1/3 black. Antennal scape white; flagellum with basal two flagellomeres white, remaining flagellomeres white and brown on dorsal surface, dark brown on ventral surface. Thorax and tegula ochreous brown. Forewing ochreous; with two parallel-sided basal white fasciae: first fascia at base, second one extending from costal 1/4 to dorsal 1/2, both edged with black scales along inside; between two fascia deep ochreous brown, from second fascia to subapex ochreous yellow; costal margin with a rounded white spot beyond costal 2/3, surrounded by black scales except on costal margin; below white spot situated a large black diffusion; apex black, termen and tornus with scattered black scales; cilia yellow except gray on apex. Hindwing and cilia gray. Tibia of midleg with a tuft of yellowish-white long scales at apex.
Male genitalia (Fig. 16). Uncus short and broad, slightly narrowed distally; posterior margin roundly and deeply concave at middle, forming two short lateral lobes. Gnathos slender, finger-shaped, about same length as uncus, lateral arms narrow-banded. Valva elongately narrow, clubbed, curved medially, with long hairs throughout. Sacculus short, with a long curved spine-like seta. Saccus broadly semicircular, with a papillary process anteriorly. Juxta broadly V-shaped. Aedeagus straight, slender, longer than valva; cornutus absent.
Female genitalia (Fig. 25). Apophysis anterioris about 1/2 length of apophysis posterioris. Lamella postvaginalis subrectangular, slightly concave at middle on posterior margin, with small triangular process anterolaterally. Ductus bursae with basal 2/5 thin, distal 3/5 gradually thickened toward corpus bursae. Corpus bursae irregularly oval; signum a large irregularly shaped plate with two processes, one thumb-like, the other crescent shaped with teeth.
Diagnosis. This new species is close to P. autoclina Meyrick, 1935 in the male genitalia, but can be separated from it by the forewing having a rounded white spot beyond costal 2/3, the uncus roundly and deeply concave medially on posterior margin, forming two lateral lobes, and the saccus bearing a papillary process anteriorly in the male genitalia. In P. autoclina Meyrick, the forewing lacks the white costal spot, the uncus is only slightly concave medially on posterior margin, and the saccus lacks the papillary process anteriorly in the male genitalia.
Etymology. The name of this species is derived from the type locality.
