( Figs 6 , 35 )

Type material. Holotype: male, China, Prov. Yunnan, Tengchong, Mt. Gaoligong , v.2013, H.L. Han & C. Zhang leg., slide HHL-2904-1, coll. NEFU.

Diagnosis. The new species could not be associated with any selected species group and obviously comprises own species-group. It is characterized by broad, triangular shape of forewing, reduced uncus, broad valva bearing short costal extension and aedeagus with vesica armed with ribbon of short setae-like cornuti.

Description. Adult ( Fig. 6 ). Wingspan 21 mm. Head and thorax ochreous-brown; forewing relatively broad, triangular; ground colour of forewing dark greenish-ochre with black-brown, wing pattern diffused; basal line marked in basal field as dark-blackish dot and dusting; inner part medial field darker than outer one; orbicular large, rounded, diffused; reniform large, rounded, pale grey, encircled with blackish scales, part of medial field outward reniform pale grey, outlined by dark ochre-grey double postmedial line; subterminal field ochre-greenish, with two small distinct subtornal marks; subterminal line pale greyish; terminal field with pale grey apical mark; terminal line interrupted, as line of blackish streaks; cilia ochre-greenish and blackish-brown. Hindwing yellowishochreous, with greyish dusting in inner part and along terminal margin; terminal area and cilia yellowish-ochreous.

Male genitalia ( Fig. 35 ). Uncus reduced, short, week, broad basally, acute apically; tegumen broad, 1.3 time shorter than vinculum; transtilla formed by broad sclerotised bands; juxta rhomboid; valva relatively short in length, width, with parallel margins, slightly constricted apically; sacculus broad, rounded; costa broad, bearing short thumb-like apical extension; ventral margin of valva broadly extended, covered with short setae. Aedeagus moderate long, broad, vesica tubular, curved and armed with long row short strong setae.

Female unknown.

Etymology. The species name refers to its characteristic wing colouration.

Distribution. Southwest China (Prov. Yunnan). The species is known only from its type-locality in Prov. Yunnan, where it occurs in mountains at altidude 1200–1500 m. Single male was collected in May.
