( Figs 2 , 24 ) Type material. CHINA , Yunnan : Holotype , Linjiapu ( 25.29°N , 98.70°E ), Tengchong , 2144 m , 14.VIII.2014 , leg. KJ Teng et al., slide No. HXM14207. Diagnosis. The new species is similar to P. ruiliensis Wang, 2006 in the male genitalia. It can be distinguished by the valva with a tuft of long setae dorsoapically, the long basal lobe of the juxta slenderly clubbed, and the long aedeagus 1.8 times length of the valva; in P. ruiliensis , the valva has a comblike scale brush along the distal 1/4 of the costa, the short basal lobe of the juxta is sub-triangular, and the aedeagus is 1.3 times length of the valva. Description. Adult ( Fig. 2 ). Forewing length 5.5 mm . Head: Vertex and frons greyish brown, occiput pale ocherous brown. Labial palpus with second palpomere ochreous yellow on outer surface, pale yellow on inner surface; third palpomere ochreous yellow, mixed with blackish brown scales. Antenna with scape white; flagellum black alternated with white on dorsal surface, blackish brown on ventral surface. Thorax: Dorsum of mesothorax and tegula ochreous yellow, tinged with grey. Forewing ochreous yellow, with rust brown and dense blackish grey scales; markings white edged with black scales: costal spot sub-triangular, crossing anterior angle of cell; basal streak slender, oblique inward to base of fold; antemedian streak from dorsal 2/5 extending straightly to below basal 1/3 of anterior margin of cell; dorsal streak from basal 3/4 extending obliquely outward to before distal 1/3 of posterior angle of cell; tornal spot small, with black scales diffused to end of dorsal streak; apical spot narrow, discontinued along termen; fringe orange yellow. Hindwing and fringe greyish brown. Fore- and midlegs white on dorsal surface, black on ventral surface, except tibiae with white spot at base and middle, with a tuft of short white scales at apex, tarsus white at apices of basal two tarsomeres; hindleg blackish brown on outer surface, whitish grey on inner surface, tarsus white at apex of each tarsomere. Abdomen: Male genitalia ( Fig. 24 ). Basal half of uncus wide, parallel-sided, distal half bifurcate, pointed at apex. Gnathos slightly shorter than uncus; mesial plate wide at base, narrowed to obtuse apex, sclerotized laterally. Tegumen narrow posteriorly, furcate from posterior 3/5; lateral arms broad, slightly narrowed to apex. Valvae elongate sub-rectangular, slightly narrower distally, weakly sclerotized in costal area; apex rounded, with a tuft of long setae dorsoapically, with dense fine setae ventroapically; sacculus heavily sclerotized, more than 2/3 width of valva basally, slightly narrowed to rounded apex distally. Saccus elongate triangular, narrowed to apex, longer than uncus. Juxta slender; basal lobe clubbed. Aedeagus long, 1.8 times length of valva; cornutus absent. Female. Unknown. Distribution. China ( Yunnan ). Etymology. The specific epithet of the new species is derived from the Latin apex and setosus , referring to the apical tuft of long setae of the valva.
