Forewing broad oval or subtriangular, field between C and ScP comparatively broad; ScP well developed and forked twice, forming three long branches; RA unforked, one crossvein between ScP and RA and between RA and RP; RP and MA both with two branches; MP with five branches, and the MP4+5 forking basal to the MP2+3 forking; MP and CuA merged at the base; CuA strongly bent at its mid point; an oblique crossvein between CuA and CuP; a curved crossvein between the midpoint of CuA and MP5; CuP, 1A and 2A almost parallel. Hind wing, similar in shape to the forewing but slightly smaller, ScP short, forked twice, the second bifurcation coalesces with RA for a short distance; RP and MA both with two branches; MP with five branches, the stem of MP4+5 forked earlier than that of forewing, and with a crossvein to CuA; CuA almost straight. Head, oviform with big and oval compound eyes; antennae long and filiform; small chewing mouthpart. Thorax: prothorax smaller than mesothorax and metathorax. Legs: long and slender, all legs nearly of the same shape, but hind legs longer than fore legs and mid legs, and femora wider than tibia, and tibia longer than femora.
