Diagnosis. This species is superficially similar to P. spilodesma (Meyrick) which is distributed in Korea, Japan, Russian Far East, Taiwan, Philippines, and India. It can be distinguished by the triangular scale tuft on the dorsum of the thorax, the longer uncus and gnathos, and the long membranous valva.
Description. Adult. Head ( Fig. 3 View FIGURES 2 – 5 ) densely scaled, pale yellowish brown. Labial palpus blackish gray dorsally, about 3 times as long as horizontal diameter of compound eye; 2nd segment with fuscous band near the base, 1.2 times as long as horizontal diameter of compound eye; 3rd segment creamy white, slender, with a fuscous band preapically, pointed apically, as long as 2nd segment. Thorax ( Fig. 2 View FIGURES 2 – 5 ) pale brownish yellow dorsally, triangular in outline. Abdomen with creamy white line on each segment dorsally. Wingspan 12–15 mm. Forewing pale grayish brown, divided into six lobes, deeply emarginated at the first cleft; 1st lobe rather thick, ground color pale yellowish brown, with four large blackish brown spots, all spots with whitish marginal line laterally; spot I near the point of branching between 1st and 2nd lobes; spots II and III on middle at regular interval; spot IV before apex; median fascia on 2nd–6th lobes located at level of 2nd spot of 1st lobe, with spot of similar width as II of 1st lobe; subterminal spots on 2nd–6th lobes between costal spot III and IV. Hindwing lobes similar to those of forewing, but somewhat slender and weaker.
Male genitalia ( Fig. 6 View FIGURES 6 – 7 a–c). Tegumen narrow, well sclerotized near base of uncus. Uncus narrow, fairly long, uniform in width, rather thick with somewhat round apex. Gnathos long, thick, nearly as long as uncus, slightly narrowed terminally. Valva somewhat broadened in distal half, membranous, rounded terminally. Juxta long, sickleshaped, membranous, slightly broadened beyond middle. Phallus ( Fig. 6 View FIGURES 6 – 7 c) nearly straight, heavily sclerotized ventrally, longer than valva; coecum as long as valva; a large hornshaped cornutus in vesica. Vinculum short, coneshaped, within folded 8th abdominal segment ( Fig. 6 View FIGURES 6 – 7 b); 8th sternite seedshaped, narrowed terminally. Abdomen ( Fig. 7 View FIGURES 6 – 7 ) with an upper liplike sclerotized part on each segment from 2nd to 6th.
Female genitalia ( Fig. 8 View FIGURES 8 – 9 ). Papilla analis slightly rolled inward near middle. Apophysis anterioris as long as posterioris. Ostium bursae wine glassshaped; postvaginal plate oblong. Corpus bursae short, ovate, membranous, minutely granulated on entire surface; signum absent. Ductus bursae nearly as long as corpus bursae, slightly widened beyond 1/3 towards corpus bursae; ductus seminalis arising from 2/3 of ductus bursae. Abdomen ( Fig. 10 View FIGURES 10 – 11 ) with upper liplike sclerotized part on each segment 2 to 6.
Distribution. Vietnam (North).
Etymology. The specific name is derived from the Latin niger (= black) and fascia (= band), referring to the characteristic wing pattern of the new species.
