Description
Description. Imago (Fig. 5). Wingspan 13.5 mm. Head with vertex white, frons brownish yellow. Labial palpus with second segment ochreous yellow on outer surface, golden yellow on inner surface; third segment dark ochreous yellow. Antennal scape white; flagellum with basal three flagellomeres white, remaining ones white and black on dorsal surface, black on ventral surface. Thorax and tegula deep ochreous yellow. Forewing ochreous yellow; markings white edged with black: first fascia extending obliquely from base of costa to near base of dorsum, second fascia from basal 1 / 4 near costal margin to middle of dorsum; costal 3 / 4 with a triangular spot; a grayish white stripe from below costal spot diagonally to before tornus; black scales scattered from apex, along termen to tornus; cilia orange yellow except deep gray on apex and on tornus. Hindwing and cilia grayish brown. Tibia of foreleg with a tuft of short white scales at both middle and apex; tibia of midleg with a tuft of long white scales at apex. Male genitalia (Fig. 17). Uncus bell-shaped, basal half almost parallel sided, sharply narrowed from about 1 / 2 to 3 / 4, distal 1 / 4 slender and stick-like, rounded apically. Gnathos about 3 / 4 length of uncus, broad at base, slightly narrowed to 2 / 3, then gradually widened toward bluntly rounded apex. Valva short and broad; costa very short, slightly projected beyond middle; apex semicircularly concave above sacculus, with a sclerotized oxhorn-shaped dorsoapical process, asymmetrical: left process reaching as far as end of sacculus, right process slightly longer than left one, exceeding end of sacculus. Sacculus with basal 1 / 2 parallel dorsoventrally, concave in V shape at about 3 / 5, produced to a strongly sclerotized distal process, which is curved, roundly protruding dorsally, apically pointed and directing upward. Juxta with anterior half thin, posterior half divided into two crescent-shaped lateral lobes. Saccus about same length as uncus, rounded at apex. Aedeagus straight, about 1.4 times length of sacculus, with two strong apical spines: dorsal one slender and longer, ventral one thick and short, hook-like, pointed apically; cornutus spiniform, about 3 / 10 length of aedeagus, with a small process at middle. Female genitalia (Fig. 26). Apophysis anterioris about 3 / 5 length of apophysis posterioris. 7 th sternite with large rumples. Ostium bursae widely open. Ductus bursae about 2 / 3 length of corpus bursae, sclerotized entirely, gradually broadened toward corpus bursae, with several strong spines anteriorly. Corpus bursae broad, elongate oval; signum short cylindrical, with a chain of short spines on each side.
Diagnosis
Diagnosis. This species is superficially similar to P. bathroclina Meyrick, 1918 and P. akaganea Fujisawa, 2002 but differs from them in the valva bearing an asymmetrical oxhorn-shaped dorsoapical process, and the sacculus concave in V shape at about 3 / 5 of its length in the male genitalia; and by the short and cylindrical signum with a chain of short spines on each side in the female genitalia. In P. bathroclina and P. akaganea, the valvae lack the dorsoapical process, and the sacculus is gradually narrowed to apex; and the signum is rounded with rough surface in P. akaganea. The female of P. bathroclina is still unknown.
Etymology
Etymology. The species epithet is derived from the Latin tauricornis (= oxhorn-shaped), referring to the dorsoapical process of the valva which reminds of a bull’s horns.
