Durgades aviana Viraktamath 2004: 367 , figs 1–8. HOLOTYPE ♂, INDIA: Simla (UASB, examined).

Color. Ochraceous. Face with median inverted Y-shaped marking on upper part, arms fused with lateral stripes on face, latter anteriorly fused with each other and occupying entire clypellus, apices of lora, black. Elongate oval to oval spot on either side of median line near vertex, transverse stripe connecting outer margin of ocellus with inner margin of eyes and broader near eye, black. Antennal cavities black, ledge of antennae ochraceous. Spot on inner margin of gena near lorum black in some specimens. Pronotum anteriorly broadly, with lateral, caudal and median slender color extensions not reaching lateral and caudal margins, black. Scutellum black with lateral, and caudal apex beyond median impressed line, ochraceous. Forewings with some segments of venation and some cells brown. Forefemora marked with brown. Thoracic pleura and abdominal segments chocolate brown with ochraceous margins. Subgenital plates ochraceous.

Male genitalia. Pygofer dark pigmented, caudodorsally produced into attenuated process with preapical finger-like process. Styles elongate, delicate, inner arm longer than outer arm and apically pointed. Connective black, wider at base and as wide as long. Aedeagus in lateral view with short dorsal apodeme with bifid membranous sclerite, preatrium shorter than in D. dunchensis and bears short process, shaft basally bulbous in lateral view and apex resembles head of bird with beak; gonopore apical, large, with lateral lamellate expansion. Anal collar process simple, produced into short finger-like process.

Material examined. HOLOTYPE ♂, INDIA: Himachal Pradesh: Simla , 2133m, 14.x.1979, C.A. Viraktamath ( UASB) . PARATYPES: 10 ♂, same data as holotype except collected by K.D. Ghorpade (2 ♂), A.R.V. Kumar (8 ♂) ; 9 ♂, with same data as holotype except 18–21.x.1981 by I. Dwrakowska ; 5 ♂, Manali, 10.x.1979, C.A. Viraktamath ( UASB) .

Remarks. This species can easily be recognized by the two cross veins between the claval veins of the forewings and by the structure of the male genitalia. It resembles D. dunchensis , but differs in the structure of the pygofer and aedeagus.
