Description
Description. Imago (Fig. 2). Wingspan 8.5–10.5 mm. Head with vertex shining white, frons brown. Labial palpus with second segment dark ochreous yellow on outer surface, yellow on inner surface; third segment black. Antennal scape white; flagellum with dorsal surface white on basal 1 / 3, white ringed with black on distal 2 / 3, ventral surface dark brown. Thorax and tegula dark ochreous brown. Forewing ochreous brown, with mottled black scales; markings white margined with black: first fascia extending obliquely from base of fold to near base of dorsum, second fascia parallel to first one, extending obliquely from basal 1 / 3 near costal margin to middle of dorsum; costa with a rounded spot at distal 1 / 4; apex gray with black scales; cilia orange yellow except deep gray on tornus. Hindwing and cilia gray. Tibia of midleg with a tuft of long white scales at apex. Male genitalia (Fig. 14). Uncus broad at base, slightly narrowed from base to 2 / 3, obviously narrowed from distal 1 / 3 to acuminate apex. Gnathos tongue-shaped, granulous on anterior half, rounded at apex, about same length as uncus. Valva subrectangular, parallel dorsoventrally; apex with two processes: dorsal one strong, curved, as long as costa; ventral one slender in basal half, bilobed and clubbed in distal half, apically exceeding the end of dorsal process. Sacculus wide basally, narrowing to apex. Juxta narrow at base, gradually widened to before apex, then narrowed to acute point; distal 1 / 3 with a large ovate cluster of fine spines. Saccus about same length as gnathos, nearlly parallel sided laterally, rounded apically. Aedeagus longer than valva, more or less curved basally, pointed at apex; cornutus absent. Female. Unknown.
Diagnosis
Diagnosis. This species is externally similar to P. suzukiella (Matsumura, 1931), P. parasuzukiella Wang, 2006, P. grandisticta Wang & Zheng, 1998, and P. albipunctata Park & Park, 1998 in having a rounded costal spot, but can be separated from them by the processes of the valva (dorsoapical process long and curved, ventroapical process distally bilobed and clubbed) and by the ovate cluster of fine spines in the distal 1 / 3 of the juxta in the male genitalia.
Etymology
Etymology. The specific epithet is derived from the Latin prefix fasc - (= cluster) and the word spinatus (= spinous), referring to the ovate cluster of fine spines on the juxta.
