Identification: Almost same in size as O. bidentata ; tegmina is well developed, narrowly surpassing the apex of abdomen; hind femur with a uniform colour of pinkish red; ♀ are fairly larger than ♂; antennae filliform with 22 segments, shorter than collective lengths of head and pronotum; frontal ridge sulcate; dorsum of pronotum moderately cylindrical.

♂ genitalia: Supra-anal plate rounded triangular in shape, basilateral folds absent; cerci conical with bifid apex, exceeding well beyond supra-anal plate; subgenital plate long and broad, apical half somewhat triangular with a median transverse profile; epiphallus expansive, plate-like bridge and divided, ancorae strongly developed and hook like with apex almost obtuse, anterior projections of lateral plates obtuse, posterior projections ample and rounded, lophi hook-like and well spaced; basal valves of aedeagus broader and flattened, apical valves short and acute; apodemes of cingulum long with no posterior emargination.

♀ genitalia: Subgenital plate long and broad, ventral surface of subgenital plate weakly convex, posterior margin triangle-like bearing comparatively a much longer process; cerci conical with subacute apex; supra-anal plate triangular; the dorsal and ventral valves of ovipositor bear sharp spines, posterior ventral basivalvular plate without spines; apical diverticulum of spermatheca moderate and not at all coiled, with a single small subdiverticula, apex of apical diverticulum acute; preapical diverticulum wide and much longer than apical diverticulum.

Geographical distribution: India: Kashmir, Java
