Type species. Urvaschia pterosticta Hopp, 1987. Diagnosis (modified from Hopp 1987 ) (Figs 1 , 2 ). Body elongate oval. Less than half length of first segment of antenna exceeding clypeus. Head short with eyes near to pronotum (less than one half diameter of eyes); bucculae short, only reaching base of antennae; labium almost reaching mesocoxae. Forewing slightly exceeding tip of abdomen; corium clearly punctate, at least between Cu vein and clavus; clavus punctate; membrane with thick veins, with distal ends fused to form four closed cells on membrane; corium and membrane between the veins covered with conspicuous brown spots. Profemur unarmed or sometimes with one very tiny spine. Figure 1.

Dorsal and ventral views a, d Urvaschia obscuripennis comb. nov. b, e Urvaschia convexa sp. nov., holotype c, f Urvaschia recta sp. nov., holotype. Differential diagnosis. Urvaschia differs from Microplax Fieber, 1860 by lacking any spine or with a very tiny spine at the distal part of the profemur (vs. one distinct spine and some tiny spines present at the distal part of profemur in Microplax ); head short with a short postocular part which is less than 1/2 longitudinal diameter of the eyes (vs. head elongate with a long postocular part which is approximately as long as the diameter of eyes in Microplax ); corium is clearly punctate and with many tiny spots (vs. corium lacking any punctures and unicolourous or with large spots in Microplax ). Urvaschia is also similar to Camptotelus Fieber, 1860 but it can be distinguished from the latter by bucculae not enlarged laterad, first segment of antennae exceeding clypeus, and clavus punctate (vs. the bucculae enlarged laterad, first segment of antennae not exceeding clypeus, and clavus impunctate in Camptotelus ). Urvaschia can be distinguished from Leptodemus Reuter, 1900 by the first segment of the antennae exceeding clypeus and the hemelytra punctate (vs. the first segment of antennae not exceeding clypeus and the hemelytra are impunctate in Leptodemus ). The key of Pericart (1999) contains all Palaearctic Oxycarenidae genera except Urvaschia . Urvaschia runs to couplet 16 (15) (to Leptodemus ) but they differ in the above-mentioned features. The other possibility if we choose that the specimen has at least one tiny spine on the profemur, we run either to Leptodemus at couplet 22 (23) (again) or to Microplax at couplet 24 (25) if we choose "profemur has at least one distinct tooth". Therefore, no described genus has identical characters shared with Urvaschia .
