( Figs 3–4 , 28–31 , 48–49 )

Dilar dochaner H. Aspöck & U. Aspöck, 1968: 5 . Type locality: Afghanistan, Khurd-Kabul, SE Kabul, 1900 m.

Diagnosis. This species is characterized by the forewing with numerous brown spots, slightly darker proximally; the male tergum 9 with short dorsoprocessus; the male gonocoxite 9 distally with an acutely pointed apex; the male gonocoxite 10 with a barely produced apex and an anteromedially directed, digitiform subdistal projection.

Description. Male. Forewing length 7.8 mm, hindwing length 7.2 mm.

Head yellowish brown, with pale yellowish brown setose tubercles. Compound eyes blackish brown. Antennal socket dark brown. Antenna generally pale yellow but scape and pedicel yellowish brown, scape with a yellow annular stripe proximally, flagellum pectinate on most flagellomeres, medial branches much longer than those on both ends, longest branch nearly 3.0 times as long as corresponding flagellomere, distal seven flagellomeres simple.

Prothorax pale yellow, pronotum pale yellow, dark brown at middle, with two pale yellow rounded markings medially; mesothorax yellowish brown, mesonotum yellowish brown and dark brown on lateral margins; metathorax pale yellow, metanotum slightly darker on lateral margins. Legs yellow with yellow setae, femora dark brown at tip. Wings slightly smoky brown. Forewing 2.6 times as long as wide, with numerous brown spots, proximal spots slightly darker, arranging irregularly; veins generally pale yellow. Hindwing 2.5 times as long as wide, paler than forewing.

Abdomen brown. Tergum 9 in dorsal view with an arcuate anterior incision, a nearly U-shaped posterior incision, and a short dorsoprocessus ( Fig. 28 ), leaving a pair of broad hemitergites, which are obtuse distally and densely haired. Sternum 9 shorter than tergum 9, arcuately convex posteriad and bearing long setae in ventral view. Ectoproct in dorsal view subtrapezoidal, posterodorsally with a pair of short tubercle-shaped projections, posteroventrally with a pair of curved bifid unguiform projections (visible in dorsal view) ( Fig. 28 ) and a short feebly sclerotized digitiform process (visible in caudal view) ( Fig. 31 ). Gonocoxite 9 ( Fig. 29 ) in ventral view slightly shorter than gonocoxite 10, distally with an acutely pointed apex. Gonocoxite 10 in ventral view with apex obtuse, barely produced; subdistal projection long, digitiform, directed anteromedially. Gonocoxite 11 forming an arcuate sclerite, connecting to bases of gonocoxites 9 and 10. Hypandrium internum subtrapezoidal.

Materials examined. Holotype, ♂, Afghanistan: Khurd-Kabul , SO von Kabul, 1900 m, 23.V. 1965, leg. E. & A. Vartian ( HUAC); 1♂, Afghanistan: Nangarhar, Safed Koh [Mountain], Südseite Kotkai, 2350 m, 21.VI.– 1.VII.1969, leg. E. & A. Vartian ( HUAC).

Distribution. Afghanistan (Kabul, Nangarhar).

Remarks. This species can be distinguished from all the other Dilar species from Central Asia by the male gonocoxite 10 with barely produced apex and long, anteromedially directed, digitiform subdistal projection ( Fig. 29 ).
