( Figs 13 , 35 ) Type material. CHINA , Yunnan : Holotype ♂ , Taiyanghe Nature Reserve ( 22.68°N , 101.03°E ), 1450 m , 23.VIII.2014 , leg. ZG Zhang , slide No. JYY17594 . Paratype ( 1♂ ): Taiyanghe National Forest Park , Pu’er City , 1450 m , 6.VII.2015 , leg. KJ Teng , slide No. JYY17912 . Diagnosis. The new species can be easily distinguished from other members of the group by the juxta with a pediform apical process that is serrate on the posterior margin. Description. Adult ( Fig. 13 ). Forewing length 6.0‒ 6.5 mm . Head: Vertex shining white, frons silvery brown, occiput rust brown. Labial palpus with second palpomere dark rust brown on outer surface, whitish yellow basally and orange yellow distally on inner surface; third palpomere blackish brown except white at apex. Antenna with scape white; flagellum black, with white annulations on dorsal surface. Thorax: Dorsum of mesothorax and tegula rust brown. Forewing orange yellow except rust yellow between fold and dorsum; markings white edged with black scales: costal spot sub-ovate, extending to above posterior angle of cell; slender basal streak extending obliquely inward to above base of fold; antemedian streak from dorsal 2/5 to basal 2/5 of anterior margin of cell, slightly oblique inward; dorsal streak from basal 3/5 obliquely outward to below and before posterior angle of cell; tornal spot small, with dense greyish black scales around; apical and terminal spots not well separated, interrupt by black scales; fringe orange yellow except grey around tornus. Hindwing and fringe greyish brown. Fore- and midlegs white on dorsal surface; ventral surface black, tibiae with white scale tufts at apex, tarsi with basal two tarsomeres white distally; hindleg greyish brown, basal tarsomere white distally, rest tarsomeres white except second and third tarsomeres black basally. Abdomen: Male genitalia ( Fig. 35 ). Uncus campanulate, basal 2/3 broad, distal 1/3 abruptly narrowed to a cylindriform. Gnathos longer than uncus; mesial plate triangular, narrowly rounded at apex, entirely cataphracted; basal arms short, dilated basally. Tegumen furcate from posterior 1/2; lateral arms slightly narrowed to rounded apex. Valvae narrowly elongate, distal 1/4 narrowed to hooked and pointed apex, with five denticles evenly spaced along costal margin, bearing long setae on ventral margin; sacculus wide, heavily sclerotized. Vinculum narrowly banded; saccus small, triangular. Juxta heavily sclerotized, reaching apex of uncus; pediform apical process extending straightly toward left, curved at a right angle, with strong spines distally, serrate along posterior margin. Aedeagus shorter than valva, spatulate distally, with dentations apically; cornutus absent. Female. Unknown. Distribution. China ( Yunnan ). Etymology. The specific epithet is derived from the Latin pedatus , referring to the shape of the apical process of the juxta.
