Identification: Slightly larger in size than O. bidentata , tegmina is well developed, marginally shorter and exceeding beyond the tip of abdomen; ♀ are larger than ♂; antennae filliform, 22 segmented; apical quarter of hind femur pinkish brown; mesosternal space open, mesosternal lobes rounded.

♂ genitalia: Supra anal plate triangular with subacute apex; cerci bifurcated and exceeding a little beyond the supra-anal plate; subgenital plate broad and converging towards apex; epiphallus broad and large, plate-like bridge and divided, ancorae strongly developed and hook like, lateral plates relatively shorter and often slightly bent outwards from outer margins, anterior projections of lateral plates rounded, posterior projections rounded, lophi widely spaced and rounded, not at all hook-like; basal valves of aedeagus much longer, apical valves shorter than valves of cingulum; apodemes of cingulum long with no posterior emargination.

♀ genitalia: Subgenital plate much broader with its surface slightly convex, posterior margin triangular having a long process; cerci conical with subacute apex; supra-anal plate elongated and triangular; the dorsal and ventral valves of ovipositor bear short and blunt spines, posterior ventral basivalvular plate without spines; apical diverticulum of spermatheca narrow, very long and convoluted with a number of small subdiverticula, apices bulged; preapical diverticulum inverted V shaped and wider than apical diverticulum.

Geographical distribution: India: Kashmir, China.
