Type material.

Holotype Female, Korea, Donghae-si, GW, 12.viii.2021 (BK Byun), gen. slide no. HNUSEL-6442-coll. HNUSEL.

Diagnosis.

This species is distinguished from P. occi by the shape of the signum in the corpus bursae. In P. occi , the cross-shaped signum in the corpus bursae, while P. fibigerina has a triangular signum. Additionally, the P. fibigerina has the forewing with a more rounded apex, a whitish-beige ground color, and a terminal margin covered with more blackish scales. The hindwing is grayish with mixed black scales. Also, the new species is distinguished from P. chekiangi Fibiger, 1911 by characters of the 8th abdominal segment and the shape of the signum. The new species has the 8th abdominal segment is 2/3 length of the posterior apophyses and is well sclerotized. The antrum is strongly sclerotized. The new species has a triangular signum in the corpus bursae, while in P. chekiangi has a cross-shaped signum.

Description.

Adult (Fig. 1A ). Wingspan 11 mm. Head bend down, black; antenna filiform, black; frons rounded; labial palps porrect. Thorax and abdomen with sparse scales, beige; A8-10 dark brown. Forewing ground color whitish beige, with black line from base to costal margin; base with half-round, blackish patch; apex rounded and with four yellowish blotches; antemedial and postmedial lines parallel, wavy, dark brown; spot reniform with whitish inner area and light brown outline.

Ductus bursae long, almost straight, narrow, membranous, and dilated at junction to corpus bursae (ca twice as broad as main tube).
