Kwantung [=Lianping, Prov. Guandong], 22.vii.1922, H. Höne; 1 male, 6 females, Hoengshan [=Hengshan Mts.], Prov. Hunan, (900 m) 13.viii, genit. slide 2016f; 10.vii, 11.viii, 9.vii (genit. slide 1920), 13.viii.1933; 1 female, West Tien mu-shan, 27.vii.1932 [=West Tianmushan Mts.] (H. Höne); 1 male (w/o abd.) Berge südl. Wenchow, pr. Chekiang [=Wenzhou, Prov. Zhejiang], 29. ix.1940 (H. Höne). The holotype is in ZFMK.

Diagnosis. The new species externally differs from its congeners by the milky-white ground colour of forewing, with light yellow-greenish tint, and the well expressed contrasting black wing pattern. In male genitalia structure it is close to Victrix tripuncta , but differs by having a longer uncus, shape of juxta and valva, smaller, bended harpe and shape of aedeagus and vesica.

Description. Adult ( Figs. 1, 2 ). Wingspan 22–23 mm. Antennae simple, filiform; labial palpi short, 3rd segment about half of 2nd, proboscis weak, reduced; head covered with white scales, thorax - with white and blackish scales in mixture. Ground colour of forewing milky-white with light greenish-yellow tint, especially expressed in subterminal field; main elements of wing pattern black or brown-black, contrasting with ground colour. Basal line marked on costal area as wide dash and on Cu vein as two dots, subbasal and antemedial lines marked as black dashes in costal area, in mid part of wing they are hardly traceable, as thin interrupted line of black scales; medial field white, with medial shadow, expressed only in costal area around and behind orbicular; orbicular white, surrounded by black border and shadowed by medial shadow; reniform not expressed, however in some specimens hardly traceable, part of cell between orbicular and reniform shadowed with black; subterminal line thin, double, dentate, in ventral half of wing joined with elements of medial shadow; subterminal field with blackish patch in costal area and blackish dashes in med and near tornal angle; subterminal line not expressed, subterminal and terminal fields divided by light greenish shadow; terminal line as interrupted row of black transversal streaks; cilia speckled, white between veins, black opposite veins. Hindwing brownish-grey, somewhat darker in outer part; discal spot hardly traceable; cilia whitish-grey, dark grey opposite veins. Male genitalia. ( Fig. 9 ). Uncus cylindrical, moderate; tegumen wide, shorter than vinculum; transtilla well expressed, ribbon-like; juxta deltoid, extended basally; valva wide basally, constricted apically; sacculus broad; harpe moderate, flat, broad basally constricted apically, somewhat bended transversally; cucullus somewhat pointed. Aedeagus moderate, thinner and longer than in V. t r i p u n c t a; vesica everted perpendicularly (T-like) to aedeagus tube, broad quadrangular, bearing one flat naillike cornutus. Female genitalia. ( Fig. 15 ). Ovipositor small, papillae anales moderate, acute; apophysed posterior and anterior ones thin, moderate, almost equal in length; ostium split-like, antrum elongate, folded; ductus bursae with bended sclerotised ribbon; corpus bursae moderate, rounded, sclerotised in caudal part; ductus seminalis arising from mid part of bursae.

Etymology. The species name refers to the country in which the new species occurs.

Distribution. China, provinces Fujian, Guangdong, Zhejiang and Shaanxi.

Bryophila tripuncta Draudt, 1950 . Mitteilungen der Münchner Entomologischen Gesellschaft, 40(1): 13; Taf. III: 1.

Material examined. Lectotype, herein designated: male (dissected), Mienshan (Prov. Shansi) [=Mianshan, Prov. Shanxi] obere Hohe ca 2000 m 3.viii.1937 H. Höne / Holotype Bryophila tripuncta m Draudt/ Bryophila tripuncta Draudt / Genital Prep. ZFMK Nr. 1065 (although the type bears the label “ Holotype ”, lectotypification is necessary to promote stability because the types of Draudt (1950) are not noted as such in original descriptions; see Han & Kononenko 2010). Other material: 2 males, 1 female, Mienshan (Prov. Shansi) [=Mianshan, Prov. Shanxi] obere Hohe ca 2000 m, 28.vii, 30.vii, 1.viii.1937 H.

Höne, genit. prep. 1920m, 1921m; 6 specimens, Kuling vii.1921, genit. prep. 1922m.

Diagnosis. Adult ( Figs. 3, 4 ). Wingspan 23–24 mm. The species can be recognized by grey wing coloration with dark greenish-grey immixture and cryptic wing pattern. Antennae of male filiform. Head and thorax covered with greyish green scales; ground colour of forewing grey, wing pattern formed by black diffused lines and dark greyish-green suffusion. Basal field greenish-grey, bordered with black basal line; subbasal field greyish, with green suffusion in costal area; antemedial line black, diffused; medial field with wide greyish-green medial shadow; orbicular pale, or hardly traceable; reniform hardly traceable; cell between orbicular and reniform filled with dark greyish-green scales; subterminal line more or less distinct, thin, dentate, oblique; subterminal line indistinct; subterminal field with dark grey-greenish suffusion; terminal field grey; terminal line as row of interrupted streaks; cilia speckled, dark greenish grey between veins, pale yellowish opposite veins. Hindwing brownish-grey, with traceable discal spot and medial line; cilia yellowish-grey opposite veins, dark grey between veins. Male genitalia ( Fig. 10 ): uncus rather short; tegument shorter than vinculum; transtilla ribbon-like, juxta shield-like; valva broad basally, constricted and somewhat curved apically, rounded at apex; sacculus broad; harpe large, flat, arched. Aedeagus rather short, massive, vesica simple, bulbous, in mid part bearing numerous minute cornuti. Female unknown.
