( Figs. 7 , 12, 16 )

Material examined. Holotype: male, China, Prov. Jiangxi, Wui Shan, Xipaihe village, 1500 m, 27˚54ʹN 117˚20ʹE, July 2004, leg. Siniaev & team, genit. prep. 7343GB/ Coll. W. Speidel (Olching, Germany). Holotype to be deposited in ZSM. Paratype: 1 female, China, Prov. Jiangxi, Wui Shan, Xipaihe village, 1500 m, 27˚54ʹN 117˚20ʹE, May 2005, leg. V. Sinjaev & team (coll. Gabor Ronkay, Budapest, Hungary).

Diagnosis. The new species is close to Stenoloba marina . Externally it can be recognized by the narrower and not expressed whitish filling of subbasal, antemedial and submedial lines, the lack of prominent whitish surrounding the reniform, and less expressed subterminal line. In male genitalia it differs from S. marina by shorter reduced uncus, longer vinculum, somewhat asymmetrical valva, with costal extension stronger on right valva than on left one, tipped apex of valva, shorter and more massive aedeagus with wider vesica and stronger sclerotised rounded extension of carina.

Description. Adult ( Fig. 7 ). Wingspan 28 mm. Head and thorax covered by dark-grey with green scales, forming high grey thoracic crest; abdomen grey; forewing narrow, with almost parallel costal and ventral margins and straight outer margin. Ground colour of forewing grey, with darker greenish-grey suffusion in costal and basal area; basal spot dark greenish-grey; subbasal line greyish, diffused, pale inwardly; antemedial line double, shadowed by dark grey scales, pale-grey inside; medial shadow thin, straight grey, extended in costal area; orbicular as black spot with intrusion of red scales; another red spot with blackish scales lies on vein Cu2; reniform as black transversal streak and small black dot, surrounded with whitish dash from reniform to costal margin; submedial line grey, diffused, especially in costal area; subterminal line as row of diffused streaks; terminal line as row of greyish spots, cilia grey. Hindwing brownish-grey, somewhat darker in outer part, discal spot hardly traceable, cilia grey, with pale inner border. Male genitalia. ( Fig. 12 ). Uncus short, rudimentary, half shorter than in S. marina , tegumen and vinculum narrow, almost equal, tegumen higher than in S. marina ; juxta deltoid, wider than in S. marina , valva simple, gradually narrowed distally, tipped and slightly curved apically, costa somewhat asymmetrical, with prominent extension on right valva, not expressed on left valva (in S. marina valvae with symmetrical costal extensions); apex of valva some curved ventrally, with small, but strong spine-like setae. Aedeagus rather short, massive, much shorter than in S. marina , with sclerotized bend-like carina, bearing flat sclerotized extension, larger than in S. marina ; vesica wide, extended, curved ventrally, in medial part with small setae-like cornuti. Female genitalia. ( Fig. 16 ). Ovipositor weak, rather short, papillae anales rather elongated, apophyses anteriores and posteriores ones thin, relatively short, almost equal in length, antrum very long, extended apically and caudally, constricted medially, sclerotised, its apical extended part with shallow cut, rounded laterally; its caudal part rounded; ductus bursae short, weakly sclerotised; cervix bursae with heavily sclerotised plate, corpus bursae elongate, longer than antrum, membraneous, somewhat sclerotised and wrinkled proximally to joining with ductus.

Etymology. The name indicates the close relationship of the new species to Stenoloba marina .

Distribution. South China, Province Jiangxi.
