Spring form: male (Fig. 11O ): both wings white on the upperside and a pale yellowish hue on the underside. Apical spot blackish, sub-triangularly extending along veins to outer margin with moderately suffusion, sometimes reached vein CuA2. The 2nd and 3rd spot completely absent while the 1st and outer spot faintly developed to absent on the upperside. Underside with the 1st, 2nd and 3rd spot distinct to rather faintly developed, outer spot variable. Female (Fig. 11P ): both wings pale yellowish to yellowish with intensively brownish suffusion on the upperside while yellowish on the underside, but clearly in the apical 2/5 of discocell on the upperside of forewings. Hindwings with dark powder moderately developed along veins. Summer form: male (Fig. 11Q ): both wings clearly whitish with dark powder moderately developed along veins on the underside, the 1st discal spot distinctly developed and the outer spot moderately present while other spots absent to rather faintly developed on both sides. Females (Fig. 11R ) both wings with intensively brownish or grey suffusion on the upperside while pale yellowish on the underside; upperside with the 1st, 2nd and outer spot distinctly developed and a trend of 3rd spot; discocell on the upperside of forewings almost full of dark suffusion. Hindwings with dark powder developed along veins. Distribution. Italy (S. W. Alps) Phenology. Bivoltine from June to September Male genitalia. (Fig. 5G ) tegumen broad on the basal part while moderately narrower extends to the terminal part; basal part of uncus slightly narrower as terminal part of tegumen with its median part slightly convex, apical half of uncus digitation. Female genitalia. (Fig. 6F ) posterior apophysis comparatively robust; inner distal of sterigma slightly up-curved extend to center; inner basal of sterigma setose, acute-angled connected at the basal margin; signum with its apical cordiform part elongated, moderately tapering to the basal. Note. This taxon was included in our phylogenetic analysis to clarify its relationship with morphologically similar taxa distributed in China and adjacent regions. In fact, this taxon occurs far away from East Asia. Our results also show that East Asian taxa can be clearly distinguished from this taxon.
