Basal and distal section of Sc well developed.R1 and Rs connected by a cross vien. M3 near Rs and M fordked; with 2 anal veins.Hind wings elongated, pionted, with a closed basal cell, Sc well developed. R1 arises proximal of M1; M+Cu1basally separated from R , M1 and M2 arises separately from R+M. Cu1 not forked, with 1 anal vein. Veins and membrance, especially in distal part of wings, setose, margin with long haires. Claws with 1 prcapical tooth; pulvillus slender, expanded apically. Subgenital plate simple.
