Strial punctures evident, very small, shallow; striae not impressed throughout length. Membranous wings present. Abdominal ventrite 1 of male slightly raised in middle near posterior margin with small transverse patch of setosity at tip; of female, uniformly convex in middle near posterior margin. Ventrite 5 of male concave medially towards apex, impression finely setose; of female, uniformly convex, not setose. Legs with front femora with ventral margin with small, blunt tooth, tooth absent (or nearly) on middle and hind femora; tarsal claws lacking basal tooth.
