Diagnosis. Forewing length 22–25 mm. Wings brown. Forewing upperside with inner margin of subapical spots in R3–R5 almost in line; spot in space M3 smaller than spots in M1, M2 and CuA1; spots in cell and space CuA1 separated apart; two spots in CuA2 separated, lower spot larger; forewing underside with basal yellow striping well developed. Hindwing upperside with the spot in space Rs large and distinct.

Male genitalia ( Figs. 28–33 ). Gnathos densely covered with spines and truncated end; valva nearly rectangular with dorso-distal part small and V-shaped; aedeagus robust, slightly longer than valva, with a curved cornuti, suprazonal sheath longer than subzonal sheath; juxta quadrifurcated with lateral branches shorter than half central branches, and with spherical mid-basal process.

Female genitalia ( Fig. 34 ). Papillae anales triangular, covered with hairs; posterior apophyses slender, longer than papillae; posterior lamella broad, weakly sclerotized, with almost rounded or rectangular distal projection; ductus bursae screlotized with middle part narrow and distal part expanded; bursa copulatrix membranous, elongate.

Distribution ( Fig. 68). China (Sichuan, Henan, Shanghai, Jiangsu, Hubei, Zhejiang, Fujian, Guangdong), Laos, Vietnam.

Remarks. The species, described by Felder & Felder (1867) from Shanghai, is widely distributed, and there are some geographic differences within China ( Devyatkin, 2000). We compared the specimens from different localities. Wing markings and male genitalia are identical but the forewing length shows a slight difference. Specimens from South West China (female, n= 2, 22–23 mm) and South China (male, n= 4, 22–24 mm and female, n= 1, 22mm) are smaller than that from East China (Zhejiang) near the type locality (male, n= 1, 25 mm).
