Diagnosis. The apical area of male ninth abdominal tergite not contorted (Fig. 6H–I), the processes of tenth abdominal stergite slender and longer than styli (Fig. 6F, G, H, L); ventral process of basal margin of female subgenital plate narrower and not surpassing the posterior margin of subgenital plate, subgenital plate about 2 times as wide as long (Fig. 8F).

Additional description. Male. Radius with forks in subapical area into two veins. Media anterior of left tegmen arises from radius behind mid-length of tegmen; media posterior fuses with cubitus anterior in basal area, then divides into MP and CuA, shortly after fused and then divided again (Fig. 7C). On the right tegmen, media and cubitus anterior with common base, media anterior gives rise to MP+CuA near end of basal quarter, then MP+CuA forks behind mid-length of tegmen into MP and CuA (Fig. 7D). Both tegmina: cubitus posterior simple, free throughout; with 4 anal veins.

Female. Left tegmen (Fig. 9C): Media leaning on the radius and temporarily fused with in subbasal area and divided again; media posterior absent. Right tegmen (Fig. 9D): media fused at base with radius; cubitus forks between basal third and mid-length of tegmen into two branches, the first branch makes a curvature and receives a very short oblique connection vein from radius but remains single-branched as M+CuA1, the second branch undivided.
