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.

Key to species of genus Oxyina in male

1. Apical quarter of hind femur pinkish brown; lophi of epiphallus widely spaced and rounded, not at all hook-like.................................................................................................... sinobidentata

- Hind femur ochraceous green or pinkish red; lophi of epiphallus hook-like........................................ 2

2. Hind femur ochraceous green; lophi of epiphallus hook-like and narrowly spaced; ancorae strongly developed and hook-like with acute apex................................................................................ bidentata

- Hind femur pinkish red; lophi of epiphallus hook-like but widely spaced; ancorae strongly developed and hook like with apex almost obtuse.................................................................................... javana

Key to species of genus Oxyina in female

1. Valves of ovipositor bear diminutive spines; apical diverticulum of spermatheca short and straight, with an apical bifurcation of apex, but without any subdiverticula......................................................... kashmira sp. n

- Valves of ovipositor bear spines; apical diverticulum of spermatheca long or moderate without any apical bifurcation of apex, but with one, two or many subdiverticula.................................................................. 2

2. Valves of ovipositor bear sharp spines; apical diverticulum of spermatheca moderate and not coiled, with one subdiverticula................................................................................................ javana

- Valves of ovipositor bear sharp or short and blunt spines; apical diverticulum of spermatheca long and coiled, with two or many subdiverticula....................................................................................... 3

3. Valves of ovipositor bear sharp spines; apical diverticulum of spermatheca long and coiled with two small subdiverticula giving it a trishula shape.............................................................................. bidentata

- Valves of ovipositor bear short and blunt spines; apical diverticulum of spermatheca extensively long and coiled with many small subdiverticula......................................................................... sinobidentata
