Brechlin)/ genit. prep. 7379 GB ( GB) ; 1 male, 1 female, Indonesia, Sumbawa Dompu Madapanga , i.2000. ex coll. H. Schnitzler; genit. preparates: male: 12072 GB ; female 12073 GB ( WS). DNA Id , BC ZSM Lep 58658 and 58659

Diagnosis. Externally D. sundana hardly can be separated from the previous species and D. eurychlora . Labial palps noticeably shorter than in D. eurychlora blackish-brown laterally, with 3rd segment length about 1/3 of 2nd. Wing colour and pattern same as in D. eurychlora and D. continentalis , but slightly differs by costal marks and whitish surrounding of the reduced transversal lines. In the male genitalia the new species differs from its relatives by shape of juxta (smaller, but relatively wider than in allied species, with central longitudinal gutter and unexpressed lateral flaps); shape of valva (similar to D. eurychlora , tapered from apical third), shape of sacculus and its extensions, developed harpe, reduced ventro-apical extension of sacculus and shape and armature of aedeagus and vesica. Female differs from both preceding species by shape of antrum, ductus seminalis and bursae copulatrix. The female genitalia of D. sundana differ from those of both preceding species by shape of antrum, ductus seminalis and corpus bursae.

Description. Adult ( Figs 5, 6, 19). Wingspan: male 40–42 mm, female 43–44 mm. Facially almost undistinguished from D. eurychlora and D. continentalis , but submedial and antemedial lines of forewing more strongly marked on costal margin and the whitish surrounding of the reduced transversal lines is more traceable; labial palps shorter than in D. eurychlora and blackish-brown laterally ( Fig. 19). Other external characters like in both preceding species.

Male genitalia. ( Fig. 11). Uncus moderately long, curved basally, hooked apically, somewhat stronger than in preceding species; subscaphium sclerotised; tegumen with broad shoulders and peniculus; paratergal sclerite broad, flat; juxta smaller than in D. eurychlora , broader than high, with wide longitudinal gutter and smooth lateral flaps; valva relatively long, somewhat slimmer than in D. eurychlora , apical extension of sacculus gradually tapering and constricted apically; costa strong, extended medially; sacculus long, without subapical cut, with large straight finger-like apical extension; ventro-apical extension of sacculus expressed like sclerotised angled patch, harpe large, finger-like (minute in both preceding species); cucullus gradually tapered apically, being similar to D. eurychlora , but wider than in D. continentalis , bearing strong setae. Aedeagus slightly curved, longer and thinner than in D. eurychlora ; carina with patch of minute plate-like spines; vesica projecting ventrally, tubular, with moderate medial diverticula armed with patch of small needle-like cornuti.

Female genitalia. ( Fig. 16) Differ well from two preceding species. Papillae anales rounded-quadrangular, smaller than in preceding species; apophyses anteriores and posteriores short, almost equal in length; antrum relatively wide, with sclerotised t-shaped caudal part and weakly sclerotised proximal part; ductus bursae relatively long, with very small sclerotised wrinkle-ring medially, membranous in joining with bursae; cervix bursae weakly sclerotised, wrinkled, with small sclerotised bar; bursa copulatrix long, ovoid, extended proximally.

Etymology. The species name refers to the distribution of the species in the Sundaland.
