Figs 46A–J, 62F, 71A–H.

Idioscopus dworakowskae Viraktamath 1979a: 25–26 , 39–43.

Male pygofer ventral margin concave in middle, anal collar process almost straight, style with subapical tooth, aedeagus with shaft sinuate, apex attenuated, dorsal apodeme well developed with basal 0.66 apressed to the shaft.

Description. Female. Sternite VII 2× as wide aslong medially, narrowed posteriorly and posterior margin slightly convex ( Fig. 62F). Valvula I straight, slightly wider in proximal 0.25 then narrowed to bluntly pointed apex, sculptured area occupying almost distal 0.75 length, strigate, strigae almost vertical ( Figs 71 ABEF). Valvula II slightly curved ventrally, more or less of uniform width, with few effaced widely spaced teeth ( Figs 71 CDGH).

Material examined. HOLOTYPE ♂, INDIA: Karnataka: Jog Falls , 19.xi.1976, C.A. Viraktamth ( UASB) . Other material studed: 1 ♀, same data as holotype but collected on 18.xi.1986 collectd by B. Mallik ; 2♀, same data as holotype but collected on 4.ii.178; India Karnataka : 4♂, 1♀, Sirsi, collected at light during March and April 2005 and 2006, Radhamani, T.R; Puducherry : 1♂, 1♀, Mahé, 15.ix.1979, A.R.V. Kumar ( UASB) ; 8 ♂, 9 ♀, Makuta, May 2004, Vateria indica canopy, Y.B. Srinivasa ( UASB, NBAIR) .

Remarks. Viraktamath (1979a) adequately descrihed and illustrated the species. In this species the preatrium is not very well-developed, but has all other features of the genus. Specimens collected from Makuta on Vateria inidca canopy are slightly different from the typical specimens; a) mesoscutellum slightly lighter in color; b) aedeagal shaft is more strongly sinuate; c) female ovipositor exceeds beyond folded wings.
