( Figs 8, 9 View FIGURES 1–15 , 37 View FIGURES 36–39 )
Type material. Holotype: male, China, Prov. Yunnan, Tengchong, Guanpojiao , 1.v.2013, H.L. Han leg., slide HHL-2956-1, coll. NEFU . Paratype: 1 male, same locality and data, slide HHL-2955-1, coll. NEFU .
Diagnosis. Externally the new species similar to S. plumbeoviridis , but differs by more brownish ground colour of forewing with less expressed green tint. It similar also to other species of this group, i.e. to S. brunnescens Kononenko & Ronkay ( Fig. 22 View FIGURES 16–30 ), but the later one has green colouration only in the basal and costal areas, and its most part of the wing has brown colour. Orange subtornal mark on postmedial line not expressed. Male genitalia of the new species is similar to those of S. brunnescens ( Fig. 44 View FIGURES 44–47 ), but clearly differ by curved shape of costa and narrower and longer apical extensions of costa. The new species also differs from S. plumbeoviridis by configuration of valva and structure of vesica bearing large twin medial diverticulum and smaller second medial one.
Description. Adult ( Figs 8, 9 View FIGURES 1–15 ). Wingspan 24–25 mm. Forewing, similarly to preceding species rather narrow, with parallel margins and convex outer margin; head and thorax plumbeous-greenish; ground colour of forewing plumbeous-grey with brownish and greenish tint; wing pattern reduced, heavily traceable; basal field ochreousgreenish, separated by thin indistinct pale line, with patch of black scales on tornal margin; antemedial and medial fields plumbeous-brownish with some greenish tint; antemedial line indistinct, twin, brownish, costal area with greenish dusting and diffused dark bases of transversal lines; orbicular traceable, outlined basally by blackish scales; reniform as patch of black scales, encircled inwardly by semi-lunar blackish line; postmedial line indistinct, twin, dentate; Subterminal field brownish; subterminal line pale greenish-brown, diffused; terminal line interrupted, as line of blackish streaks; cilia plumbeous-brown, blackish at base. Hindwing ground colour brownish-grey, with light yellowish dusting, darker to terminal marhin; discal spot distinct; terminal line and cilia yellowish-ochreous.
Male genitalia ( Fig. 37 View FIGURES 36–39 ). Uncus like in S. plumbeoviridis , very small, weak; tegumen and vinculum moderate broad; tegument two time smaller than vinculum; vinculum with penicular lobes; rounded leave-like; valva relatively short, with broad base, constricted apically, ended by strong obtuse extension covered with patch of strong setae; sacculus large, elongate; costa sclerotised, strongly arched in medial part. Aedeagus moderate in length, vesica broadly-tubular, bearing large twin medial diverticulum.
Female unknown.
Etymology. The species is named by its characteristic plumbeous-grey with brown and intensive green tint colouration.
Distribution. Southwest China (Prov. Yunnan). The species is known only from its type-locality in Prov. Yunnan, Tengchong, where it occurs in mountains at elevation 1200–1500 m. Moths were collected in May.
