Forewing: Costal space with 7 crossveins, terminates distal to commencement of Rs; 4 RA cells with 6 radial veins; A2 simple and fused with A3 basally; CuP straight distal to CuP-A1. Hindwing: Costal space with 6 crossveins; A1 forked and fused with CuA for significant length distal to A1 fork; 4 RA cells with 7 radial veins.

Thorax: Pronotum brownish with yellow band in the middle, mid-section cylindrical, granulated and lacks transverse ridges in dorsal view. Pterothorax yellow with brown longitudinal bands in dorsal view; prescutum yellow; scutum yellow with scattered brown patches on lateral margins; pleural region yellow with brown spots near sutures.
