Generic diagnosis. Body medium-sized. Integument usually finely rugulose and shiny. Head conical; fastigium in dorsal view rounded pentagonal, broader than long, slightly depressed in the middle, without or with weak median longitudinal carinula; face straight or slightly oblique in profile view; frontal ridge sulcate throughout to clypeus; lateral facial keels complete. Eyes normal, oval. Antennae filiform, longer or shorter than combined length of head and pronotum. Prosternal process conical, often slightly bent backwards, with subacute or rounded apex, and sometimes with slightly flattened posterior surface. Pronotum subcylindrical; dorsum flattened or slightly rounded, smooth or finely rugulose, weakly crossed by three transverse sulci; median carina weak; lateral carina absent. Mesosternal interspace longer than wide. Tegmina and hind wings fully developed or shortened to brachypterous condition but never reduced to lobiform condition, and always touching in mid dorsal line when folded and without trace of transverse parallel stridulatory veinlets. Hind femora slightly slender, with upper genicular lobes rounded and lower genicular lobes spined. Hind tibiae expanded in apical half and with acute dorsolateral margins, external apical spines present. In male the terminal tergite of abdomen without furcula; supra-anal plate triangular, apex rounded or angulate, sometimes trilobate; cerci conical or slightly compressed laterally, apices rounded, obliquely truncate or bifid; subgenital plate short conical, apex rounded or truncate; epiphallus with divided bridge, two pairs of lophi and without ancorae. In female, subgenital plate usually with longitudinal carina or sulcus, posterior margin with teeth or prominences; ovipositor valves long, slender, unevenly spined or evenly serrate.

Distribution. Ethiopian, S.E. Palaearctic, Oriental, Austro-Oriental, Australasian regions.

Remark. The genus Oxyoides was established with Oxyoides wulingshanensis as type species. Since Oxyoides wulingshanensis is a new junior synonym of Oxya agavisa Tsai (see the remark under Oxya agavisa), it follows that the genus Oxyoides is a new junior synonym of the genus Oxya, as well.
