Type species: Xiphidiopsis emarginata Tinkham, 1944

Size small. Long-winged species. Head with bluntly conical fastigium of vertex, and with a longitudinal groove at middle of dorsal surface. Last segment of maxillary palpi about equal to the preceding one. Pronotum not very long, humeral sinus hardly indicated. Tegmina and hind wings considerably surpassing apices of caudal femora. Male stridulatory apparatus developed. Fore coxae with a spine. All femora unarmed. Lower lobes of hind knee bluntly rounded. Fore tibiae with open tympanum on each side. Hind tibiae with three pairs of apical spurs. 9 th abdominal tergite of male with a median process. Cerci of male symmetrical or asymmetrical. Subgenital plate of male with paired styles. Ovipositor as in Teratura (Megaconema) Gorochov (2005) , with ventral margin denticulated.

Discussion. The new genus differs from the other genera of Meconematini by the highly modified 9 th abdominal tergite of male and denticulated ventral margin of ovipositor.

Distribution. China, Laos.
