ẸDzDza

Diagnosis. Body large, green when alive. Wings reaching the apices of hind tibiae, hind wings slightly longer than tegmina. The internal apical spine of hind tibiae obviously larger than the internal one. Male ninth abdominal tergite with 1 pair of median hooks, its apices directing outwards; cerci longer, about three times along as subgenital plate; posterior margin of subgenital plate triangular concave. Female seventh abdominal sternite with 1 long process, its apex with curly lateral lobes; between seventh abdominal sternite and subgenital plate with some transverse riffles, posterior margin of subgenital plate concave.

Discussion. The new genus is similar to Phryganogryllacris Karny, 1937 but the body is green and slender in appearance. It differs from the latter genus by the male ninth abdominal tergite processes do not arise from the latero-apical margins of the tergite but as medial appendages, and the female seventh abdominal sternite with 1 long process. And the established new genus differs from Metriogryllacris gialai group by females bearing a long process.

Etymology. The name of the new genus is a combination; meaning it is mainly distributed in China.

Species included. The new genus includes type species and Phryganogryllacris vinhphuensis Gorochov, 2005 . And the other undescribed species of the genus are also found in Guangxi and Hainan, China.
