Wings: ( Fig. 4F ) fore wing 3.14 × as long as its maximum width and 1.37 × the hind wing length; hind wing vein 1cu-a distinctly postfurcal; 1-SR+M sinuate; r: SR1+3SR: 2SR= 1:6:2; 1-M 0.4 × as long M+CU; pterostigma densely setose, 3.0 × as long as its own width, 1-SR absent; r-m absent; Cu1b broader than 3-CU1; hind wing vein 1A present; 1M 1.75 × as long as 1r-m.

Legs: hind coxa robust and coarsely rugose, 1.8 × as long as wide, tarsal claws simple; length of femur: tibia and basitarsus of hind leg =43: 55: 28; hind basitarsus longer than combined length of the rest of tarsi, tibial spur 0.57 × basitarsal length; hind femur 4.0 × as long as wide; hind tibia longer than femur and 6.25 × longer than its maximum width; each hind tarsus with apical spines except telotarsus; tarsal claws simple ( Figs 4K–M ).

Metasoma: ( Figs 4 H-J) 3.25 × as long as wide and heavily sculptured, length of first tergite 1.3 × longer than it maximum width, coarsely rugose, with two basal carinae; laterope deep and round; second tergite wider than long, basal half of second and third tergite reticulo-punctate; whereas the apical portion of T2, T3 and whole T4 strongly rugose; rest of posterior metasomal tergites sparsely punctate laterally, T5, T6 smooth, with few lateral setae; suture between T2 and T3 broad with strong longitudinal carinae; third to seventh tergite sparsely punctate laterally; length of ovipositor sheath 0.68 × fore wing length.

Remarks: The new species described is close to O. rugosus , can be differentiated by the combination of characters in Table 1 .

Etymology: The species is named after the country from where it is described ‘India’.
