Description. ♂ ( Figs. 1–2 ) Antennae length 7.0– 7.5 mm, dark brown, base of club ventrally yellowish, apiculus hooked. Length of forewing 14.5–15.5 mm. Forewing upperside dark brown with yellow spots; apical spots in spaces R3–R5 arranged in line, upper and lower cell spots merged, with the lower prolonged towards wing base; spots in spaces Cu1 and M3 overlapped; spot in middle of space Cu2 minute. Forewing underside yellowish, except spaces Cu1, Cu2 and 2A dark brown; veins and termen black; yellow spots as in those on upperside; a series of small black postdiscal spots forming a curved row. Hindwing upperside dark brown, with two sharply marked yellow spots in spaces Cu1 and M3. Hindwing underside yellowish, with many small black spots in postdiscal and submarginal area; veins and termen black. Cilia of forewing chequered with black and yellow, and those of hindwing uniformly yellow.

Male genitalia ( Fig. 9 ): Uncus as long as tegumen, deeply divided, side processes triangular, very small. Gnathos bifid, shorter and wider than uncus, terminally serrated. Saccus short. Valva nearly rectangular, ampulla conspicuously elongated, outer margin slightly serrated; harpe nearly rectangular, apical margin round with dense sharp teeth. Phallus about 0.9 times as long as valva, with suprazonal sheath prominently 1/3 length of subzonal sheath; coecum penis inflated terminally; cornuti oval. Juxta V-shaped.

♀ ( Figs. 3–4 ) Antennae length 6.5–7.0 mm, Length of forewing 14.5–15.5 mm. Wing pattern is similar to male, except cell spot of forewing quadrate, instead of being prolonged towards base.

Female genitalia ( Fig. 11 ): Papilla analis nearly oval, covered with hairs on the surface; apophysis posterioris slender and long; lamella antevaginalis bell-shaped, strongly sclerotized, with outer margin round and inner margin concaved centrally; lamella postvaginalis nearly triangular and weakly sclerotized, with middle of outer margin slightly concaved; ductus bursae short, membranous; bursa copulatrix oval, membranous, with an appendix bursae.

Distribution. Currently only known from Qingliangfeng, Zhejiang Province, China.

Hostplant. Unknown.

Voltinism. Probably univoltine; adults occur from May to June.

Etymology. The specific name is derived from the fact that the new taxon is similar to its allied species Onryza maga in appearance.

Diagnosis. This new species can be distinguished from Onryza maga by the following combination of characters: 1) black spots on hindwing underside small; 2) underside of both wings with dark veins; 3) harpe of valva nearly rectangular, not triangular; 4) ampulla conspicuously expanded; 5) phallus with cornuti; 6) tips of uncus processes widely separated; 7) juxta V-shaped instead of U-shaped; 8) lamella antevaginalis bell-shaped, not ladder-shaped.
