R4+5 proximally straight, distally weakly curved anteriad, meeting costa before apex. R-m crossvein almost at middle of cell d but tending slightly towards its basal end. Vein M1 sinuous at base, remainder almost straight, meeting wing margin just behind apex. M2 gently evenly curved, meeting wing margin. M-m crossvein closing cell d at level of origin of M1. M3 and CuA1 gently evenly curved, ending before wing margin. Cell br longer than bm, base of M3 and CuA1 arising close together at apex of cell bm. CuA2 slightly curved posteriorly, CuP visible as a concave vein just behind CuA2. A1 well developed, with similar curvature to CuA2, ending before wing margin.
