Diagnosis of male. Males of D. peregovitsi ( Figs 1, 2 ) have a pattern similar to that of the female holotype ( Fig. 3 ), but differ in the slightly smaller size and darker body and wing coloration. In the original description ( Gyulai et al. 2014), D. peregovitsi has been treated as the closest relative of D. autumnalis ( Figs 4 , 10 ) due to similarity of its female genitalia to those of D. autumnalis, but the male genitalia of D. peregovitsi ( Fig. 7 ) are very similar to those of the Himalayan D. thaumasia ( Fig. 5 ), from which D. peregovitsi clearly differs in its much paler, bright green forewing coloration, the antemedial line stronger wavy, and the slightly smaller orbicular stigma. The male genitalia of D. chrysochlora ( Fig. 7 ) differ from those of D. thaumasia ( Fig. 8 ) by the more slender uncus, the valva more broad basally, the slightly shorter and more basally wide cucullus, the basally broader harpe, and the absence of spinules on the semiglobular ventral diverticulum of the vesica. Externally, D. peregovitsi is much more similar to Himalayan D. chrysochlora ( Figs 6 , 9 ) and Taiwanese D. autumnalis ( Figs 4 , 10 ), but can be distinguished by the slightly less dentate postmedial line and slightly darker hindwings.

Description of male genitalia ( Fig. 7 ). Uncus short, robust, hairy, apically hooked; tegumen short compared to valve, penicular lobes not developed; juxta robust, its basal section shield-like, the distal section smaller, cordiform; vinculum short compared to tegumen, V-like. Valva elongated, with almost parallel margins, only slightly broadened basally; costa with a broad medial field of hairs; cucullus robust, thorn-like; ventral pollex-like lobe broad, trigonal; sacculus as broad as a half of valve, sclerotized; harpe long, narrow, medially curved, basally broadened, apically tapered. Aedeagus elonagted, narrow, slightly curved in its distal third; carina with plate-like, apically rounded ventrolateral plate; vesica membranous, tubular, broadened medially, curved ventrally, granulated basally, with broad but short, granulated semiglobular ventral diverticulum, apically curved medial dorsal diverticulum terminating in a bunch of thin spines and a broad, rounded subapical cluster of robust spines.

Distribution. D. peregovitsi is known from the Northern and Central Highland regions of Vietnam (provinces Lao Cai and Kon Tum).
