Identification. Superficially very similar to the genus Oxya; but differs from Oxya in the fallowing characters: male epiphallus is wide and plate-like, ancorae are fully developed, the ectophallic membrane in between halves of bridge is enlarged; apical valves of penis are covered by valvular plates of cingulum; in females, the posterior margin of subgenital plate bears a single elongated spine like process, excepting this process, posterior margin with triangular profile from ventral view; Integument with fine indentation and shiny; antennae filliform, loner than head and pronotum together; pronotum slightly sub-cylindrical transversed by three acute sulci, dorsum of pronotum moderately flattened or cylindrical, median carina diminutive, lateral carinae absent; posterior margin of metazona are widely obtuse-angular, prozona larger than metazona; fastigium of vertex, from dorsal view, shallow and broad with moderately triangular apex holding a slight frontal concavity, fastigial foveolae and carinula of vertex absent; frons oblique and fairly convex, owning two parallel carinulae of frontal ridge continuing to clypeus, facial carinae prominent; eyes humongous, ovoid; prosternal tubercle simple conical bearing subacute apex; mesosternal interspace deep but constricted, mesosternal lobes somewhat rounded, metasternal space nearly closed; hind femur slender, upper knee lobes rounded, genicular lobe of hind femur with a spine; hind tibia with an apical dilation, external apical spine of hind tibia present; tegmina well developed exceeding the apex of hind femur.
