( Figs 3, 4 , 24 , 38 )

Type material. Holotype: male, China, Aut. Reg. Xizang, Linzhi, Hanmi, 2200 m, 20–28.vii.2013, Zhao-Hui Pan leg. genit. prep. HHL-2930-1. Paratypes: 1 female, with same locality, data and collector, genit. prep. HHL-2906- 2; 5 females, Aut. Reg. Xizang, Hanmi-Motuo, 2100 m, 18–27.viii.2005, H. Huang, D.K. Zhou & L. Tang leg., genit. prep HHL-2927-2; HHL-2927s; HHL-2928-2; 2929-2. Coll. NEFI, Harbin.

Diagnosis. Wingspan 41–45 mm. A. parannamita externally differs from its congeners by large size and brighter colouration with forewing pattern formed by golden-green elements on dark-brown background and especially expressed golden-green subterminal field with distinct or traceable reddish suffused subterminal line; hindwing yellowish-brown, paler compared with other species. By structure of uncus, shape of cucullus and harpe and structure of vesica the new species belongs to atrovirens -species group, being very close to A. annamita described from North Vietnam. It differs externally from A. annamita by its somewhat larger size (male 40, female 42–45 mm vs 38–40 mm in A. annamita ), generally more bright colouration and details of structure of male and female genitalia, namely by larger and less tapered cucullus, stronger harpe, structure of vesica and shape of cornutus in male, and smaller, more rounded antrum, thin, longer ductus bursae and simple shape of the corpus bursae without discoidal sclerotised posterior section of bursa copulatrix in female.

Description. Adult ( Figs 3, 4 ). Head and thorax covered with greenish-golden hair-like scales, palps blackish. Ground colour of forewing blackish-brown; main elements of wing pattern golden-green or yellow-green; basal field blackish, subbasal field filled with golden-green; costal field blackish with distinct yellowish-green marks; medial field blackish-brown with greenish suffusion; orbicular and reniform stigmata filled with black and suffused with greenish scales, encircled with golden-green, reniform with whitish outer streak; veins suffused with grey; postmedial line waved or slightly dentate; subterminal field bright, golden-green, with whitish-grey veins and reddish-brown outer suffusion; subterminal line dentate, whitish-grey; terminal field golden-green on blackishbrown background, having black dash in medial part; terminal line broken for black semilunar streaks; cilia yellowish-brown, with black terminal spots between veins. Hindwing yellowish-grey, paler in inner part, with traceable discal spot and in some specimens with diffused terminal band; cilia pale, yellowish-grey.

Male genitalia. ( Fig. 24 ). In the male genitalia, the armature larger than in A. annamita ; uncus, tegumen and valva somewhat stronger; juxta quadrangular; valva generally broader than in A. annamita , with more massive and less tapered cucullus and more angled ventral extension of sacculus; harpe relatively short, straight, somewhat stronger than in A. annamita . Aedeagus with strongly sclerotised, slightly scobinate carina; vesica rather short, with shorter, but broader compared with A. annamita diverticula; dorsal diverticulum armed with large, broad basally, strongly arched cornutus, which extended and hooked apically; medial diverticulum armed with three small comb-like cornuti.

Female genitalia. ( Fig. 38 ). The female genitalia of the new species conspicuously differ from A. annamita by twice shorter ovipositor, rounded, cup-like shape of antrum, shorter ductus bursae, by missing of discoidal sclerotised posterior section of bursa copulatrix, and by elongated, rounded in the bottom part shape of bursa. Etymology. The name of the new species refers to it close relations to A. annamita .

Distribution. China (Prov. Xizang, Linzhi). The species is known only from its type-locality.
