(Figs. 9, 21)
Type material. CHINA, Hainan Provice: Holotype 3, Mt. Jianfeng (18°25ʹN, 108°28ʹE), 940 m, 5.vi.2007, leg. Zhiwei Zhang & Weichun Li, genitalia slide No. DZH09025. Paratype: 1 3, same data as holotype, genitalia slide No. DZH09026.
Description. Imago (Fig. 9). Wingspan 8.0 mm. Head with vertex and frons yellow. Labial palpus with second segment yellow on inside, yellow mixed with black on outside, black at apex; third segment whitish yellow on basal half, black on distal half. Antennal scape yellow; flagellum yellow ringed with black on dorsal surface, dark brown on ventral surface. Thorax and tegula black. Forewing yellow, tinged with black scales; costa with three black patches: basal patch rectangular, extending outward down to 1/4 of wing above fold, edged with white along lower margin; median patch irregularly quadrangular, extending to midwing, with a white line along its outside; distal patch largest, roughly semicircular; dorsum with a quadrate black and yellow patch at middle, extending upward to below the fold, edged with white along both inside and outside; tornus with a black spot; a white line along upper edge of basal patch of costa to black spot at tornus; apex with a white dot; cilia yellow. Hindwing and cilia gray. Tibia of midleg with a tuft of short yellow scales at both middle and apex.
Male genitalia (Fig. 21). Uncus broad at base, slightly narrowed to about 2/3, distal 1/3 slender, acute at apex. Gnathos broad ligulate, about same length as uncus, distal 1/3 with fine scalelike carinae, apically with a small weakly sclerotized process. Valva broad, almost parallel dorsoventrally, triangularly protruding distally, narrowly rounded at apex; costa slightly concave basally. Sacculus about 1.5 times length of costa, distal 1/2 with dense hairs, bearing an apical process pointing upward. Juxta slender anteriorly, broadened medially; lateral lobes reaching middle of gnathos, acute at apex. Saccus about 1/2 length of sacculus, nearly parallel sided, apex rounded. Aedeagus about 1.5 times length of valva, with a sclerotized serrated process apically; cornutus spiniform, about 1/ 3 length of aedeagus.
Female. Unknown.
Diagnosis. This species is very close to P. infulata Wang, Li & Zheng, 2000 both superficially and internally, but can be separated from them by male genital morphology, in which the saccus is about 1/2 length of the sacculus, the aedeagus is narrow (about 1.5 times as long as the valva), with a sclerotized serrated apical process, and the cornutus is about 1/3 length of the aedeagus. In P. infulata, the saccus is about 1/3 length of the sacculus, the aedeagus is broad (about 1.25 times as long as the valva) and lacks the apical process, and the cornutus is about 3/4 length of the aedeagus.
Etymology. The name is derived from the Latin serratus (= serrated), referring to the sclerotized serrated apical process of the aedeagus.
