Diagnosis. Adult ( Fig. 8View FIGURES 7 – 11). Wingspan: 27–28 mm. The species could be separated from its congeners by characteristic pale greyish basal field and pale area around reniform. Thoracic crest high, rusty-greyish. Forewing rather narrow, with almost parallel margins and rounded tornal angle, wing pattern characteristic for species. Ground colour of forewing grey, with darker greyish irroration; subbasal line double, shadowed by dark scales, antemedial line twin, dark-grey, with pale grey inside, two red spots are in medial field; medial shadow thin, oblique, reniform spot as dark transversal mark, surrounded with whitish large whitish area; submarginal line double, subterminal line dark, diffused, bordered by pale yellowish-grey scales, terminal line as row of pale spots, cilia speckled. Hindwing brownish-grey, darker in outer part, discal spot traceable, cilia grey, with yellowish inner bor- der. Male genitalia ( Fig. 13View FIGURES 12 – 16): uncus weak, rather short; tegumen and vinculum narrow, almost equal, juxta deltoid, vertical, valva simple, gradually narrowed distally, rounded apically, costa with extension curved at middle; apex of valva somewhat extended ventrally, with small, but strong spine-like setae. Aedeagus large, with sclerotized bend-like carina, bearing flat sclerotized extension, vesica wide, tubular, curved ventrally, in distal part with field of cornuti consisting of small setae-like cornuti. Female unknown.

Distribution. East and South China (Provinces Zhejiang, Hunan, Sichuan, Fujian, Guangxi and Xizang Autonomy Regions).

Stenoloba speideli Kononenko & Ronkay, 2001  ( Figs. 6View FIGURES 1 – 6, 14View FIGURES 12 – 16)

Stenoloba speideli Kononenko & Ronkay, 2001  , Insecta Koreana 18 (2): 110, fig. 19, 38, 39, 52. Type locality: NorthVietnam, Tam Dao, 60 km NW Hanoi, 1200 m. Holotype: male, preserved in ZFMK.

Material examined. 1 male, China, Guandong Prov., Nanling Mts., 2003 (coll. M. Wang) ( NEFU).

Diagnosis. External appearance ( Fig. 6View FIGURES 1 – 6). Wing expanse 24 mm. The species is closely related to S. viridescens  , but differs by the more monotonous green-brownish colouration of forewing, less expressed wing pattern, small, indistinct orbicular, and less distinct whitish tornal mark. Male genitalia shows similarity with those of S. viridescens  , but differs by not having an acute and bifurcate apex of costa, which in S. speideli  bears a single strong spine; the sacculus has a well expressed clavus, its apex acute, pointed and curved inward. Female genitalia are characterized by pentagonal shape of distal margin of antrum, round shape of bursa copulatrix with expressed neck and position of cervix bursae on the neck. Head, thorax and basal part of forewing moss-green with scarce dark markings. Ground colour of forewing dark moss-green in costal and outer parts, with irroration of brown-blackish, with shining; antemedial line oblique, double, black, filled with moss-green, medial shadow diffused, blackish, marked in costal area; medial field greyish in central part; postmedial line double, blackish, filled with moss-green in mid and with grey in costal parts, with small whitish vertical mark at tornal area; orbicular as small black dot, surrounded with moss-green; reniform indistinct, expressed as thin blackish bordering line, area around reniform greyish; subterminal line distinct, defined with a darker brownish shadow, apical patch pale greyish; terminal line as row of diffused black strikes and pale greenish marks between them; cilia brownish-grey. Hindwing dark greybrown, somewhat darker in outer part, with traceable discal spot. Male genitalia ( Fig. 14View FIGURES 12 – 16): uncus very small, sticklike, vestigial, tegumen short and narrow, vinculum equal to tegumen, wide, juxta deltoid, vertical, extended at base, valva relatively short, strongly sclerotized, with well developed costa and narrow band-like rudimentary clasper, constricted and curved dorsally in apical third under strait angle; apex of valva more or less rounded, bearing single strong spine and setae; sacculus with clavus, elongate, its apical margin significantly exceeding the plate of valva, curved apically, knife-like, constricted and pointed at apex. Aedeagus shorter than valva, sclerotized at apex, vesica tubular, with small fine spinules in apical part. Female genitalia: ovipositor weak, moderate, shorter then in S. viridescens  , papillae anales rather elongated, apophyses anterior longer then posterior ones, relatively short, almost equal in length, antrum elongated, sclerotized, somewhat narrower then in other species, deep cuplike, its caudal part extended, pentagonal in shape, ductus bursae moderately long, thin, sclerotized, bursae with narrow neck in joining with ductus; cervix bursae well separated, situated on neck of bursae, with fold; corpus bursae round, membranous.

Distribution. South China, Guandong Prov. (first record for China), North Vietnam.
