(Figures 1I, J, 2E, and 4F, G)

Diagnosis

This species is similar to P. suzukiella (Matsumura) in the wing marking, but it can be easily differentiated by the presence of fuscous scales under the white costal patch before the tornus.

Description

Adult (Figure 1I, J). Head (Figure 2E): Frons greyish-brown; vertex white. Antenna with white scape entirely, as long as diameter of eye; flagellum white and dark brown alternately. second segment of labial palpus yellowish-brown; third segment dark brown entirely, except white basal part; third segment shorter than second segment. Thorax: Thorax and tegula dark brown dorsally. Wing expanse 7.0– 7.5 mm. Forewing ground colour dark brown at basal and apical parts, and yellow at middle part. White marking surrounded by fuscous scales: two oblique bands presented: one near base, the other one-third from costal margin transverse to one half posterior margin; one semi-circular costal patch at two-thirds; two fuscous patches: one before tornus; the other before apex; fringes yellow followed by the outer margin, dark brown dense before the tornus. Hindwing more or less lanceolate; fringes greyishbrown. Legs: hind leg dark brown dorsally.
