description: Stenoloba yunley Han & Kononenko sp. n.   
(Figs. 1, 2, 18, 37)  
 Type material. Holotype: male, China, Prov. Yunnan, Mojiang, 18–19.ix.2008 (coll. H.L. Han & E Liu). Paratypes: 4 males, 2 females, Prov. Yunnan, Jiangcheng, 15–17.ix.2008 (coll. H.L. Han, M.J. Qi, E. Liu). The types preserved in the collection of Northeast Forestry University, Harbin.   
 Diagnosis. The new species belongs to the S. manley group. Externally it resembles S. manley formosana Kononenko & Ronkay, 2000 (Taiwan) and S. bachmana Kononenko & Ronkay, 2000 (N. Vietnam), but can be distinguished from both species by more contrasting wing pattern and by characteristic grey sheen, most strongly expressed in apical part of wing. The male genitalia of the new species differ from those of S. manley by narrower apical part of valva and shape of abrupt cucullus; from S. bachmana it differs by constricted shape of valva; the female genitalia differ from both species by shorter antrum and larger and more sclerotized lateral plate in the posterior part of corpus bursae.   
 Description. Adult (Figs. 1, 2). Wingspan 29–30 mm. Head and thorax brownish, mixed with ash-grey and greenish scales. Thorax ash-grey with greenish; thoracic crest high, built up from ash-grey, brown and reddish scales, with greenish tint. Ground colour of forewing pale brownish-grey (paler than in S. manley formosana, but darker than in S. bachmana) with somewhat greenish tint. Basal field grey with black scales, yellowish-green in costal area. Subbasal line double, pale yellowish-green; antemedial line double, formed by black lines, filled by yellowish green; postmedial line double, its outer line thin or inconspicuous, finely dentate; subterminal line expressed by row of blackish streaks, terminal line as row of broken streaks. Antemedial field darker than ground colour, with well expressed wide black claviform; orbicular indistinct, blackish; reniform wide, in inner part bordered with black, in central part with red or reddish scales; subterminal and terminal fields with intensive ash-grey suffusion; costal area somewhat paler, with well expressed base of lines. Cilia grey. Hindwing dark greyish-brown, darker in outer area. Cilia brown, with pale greyish or pale yellowish inner line.   
 Male genitalia (Fig. 18). Uncus developed, rather short and thin; tegumen and vinculum thin, tegumen 1.3 times higher than vinculum; juxta broadly rhomboidal, with apical extension; transtilla well developed, with sclerotized plates. Valva rather ample, with massive costa, slightly asymmetrical, from base to mid part with parallel margins, somewhat constricted in middle (less than in S. manley, with more wide “neck” and narrower distal part); distal part expanded, but less than in S. manley; apical part of rhomboidal shape, with well expressed apical and tornal angles, almost completely covered with field of strong setae; right valva somewhat wider than left one; sacculus long, bulged, clasper as a longitudinal plate. Aedeagus relatively long, significantly curved in middle; vesica broadly tubular, bearing single, large, massive cornutus, conspicuously larger than in S. manley.   
 Female genitalia (Fig. 37). Ovipositor weak, short, quadrangular; apophyses anteriores and posteriores equal in length; antrum long, shorter than in S. manley, flattened, more or less quadrangular, somewhat expanded on top, sclerotized in medial part; ductus bursae short, sclerotized; cervix bursae small, weakly sclerotized; corpus bursae elongate, with large, long, much more strongly expressed than in related species, sclerotized lateral plate on left side.   
 Etymology. The species name “ yunlei ” is formed by first parts of words “ Yunnan ” and last part of “ manley ”.   
 Distribution. The species is known only from its type-locality, Prov. Yunnan, South China.
