Tegmen triangular with apical angle rounded and sutural angle right-angled or acutely produced dorsally. M1+2 branched level with apex of clavus. Coloration green or grey-green, often fading to yellow in dried specimens. Males usually duller than females. Apex of head, apices of fore- and mid-tibiae and all tarsi and often lateral angles of frons marked with red. Tegmen with minute granulations in all cells leaving bare circular spot in centre of each cell. Costal margin pallid, then narrowly red around apical margin and claval margin to apex of clavus. Individuals may lack all red coloration and show other variation.
