Diagnosis. Adult ( Fig. 1, 2, 18). D. eurychlora and allied species can be recognized by characteristic wing colouration and maculation uniformly stable in most species (except D. sailendra ). Wingspan male 43 mm, female 40–43 mm. Head covered with salad-green and brown scales; labial palps rather long, grey-yellowish laterally grey-brownish; 3rd segment of palps stick-like rather long, about half or third of length of the 2nd ( Figs 18–20), grey-yellowish; thorax salad-green, collar with brown scales; abdomen yellow or yellowish-brown with thoracic crest. Forewing salad-green, basal line as small brown patch, wing pattern formed by three brown patches in costal part of subbasal field, in subterminal and terminal area and in tornal angle; reniform and orbicular not presented; transversal lines indistinctly marled by thin broken brown lines. Hindwing yellow with broad fuscous terminal band, reduced traceable medial line and small green, black outlined anal mark. Underside of forewing yellowish grey, with darker medial and terminal area, hindwing with diffused terminal band. Male genitalia. ( Fig. 9): juxta broad, with two longitudinal bars and lateral flaps; sacculus long and rather broad, bearing pointed apical extension and heavily sclerotised finger-like latero-apical extension; valva gradually narrower apically; clasper as transversal bar, harpe very small; cucullus narrow, covered with dense hairs. Aedeagus moderate in length; carina with small spine, vesica tubular, projecting ventrally, extended medially, bearing small subbasal patch of small cornuti and large subapical diverticula armed with patch of small need-like cornuti. Female genitalia ( Figs 13, 14): papillae anales rounded-quadrangular; apophyses anteriores and posteriores short, almost equal in length; antrum rather wide, with sclerotised caudal part and weakly sclerotised proximal part; ductus bursae relatively short, with sclerotised wrinkled patch medially, membranous in joining with bursae; cervix bursae heavily sclerotised, wrinkled; bursa copulatrix rounded, membranous; ductus seminalis arising from caudal part of bursae.

Distribution (Map. 21). North India, Nepal, Malaysia (Genting Sempan).

Note. The former records of D. eurychlora from China (Hreblay et al. 1998) belong most probably to the next species.
