C strong, ending beyond wing apex, at which R4+5 ending. Sc1 relatively long, approx. 0.4 times the length of wing, ending far distad of the intersection of bRs and r-m. Humeral vein distinct and oblique. Sc2 well developed, starting in front of bRs. Cell r distinctly small (0.89 mm), approx. 0.165 times the wing length (5.4 mm). Section of R from Sc2 to bRs origin approx. 2.4 times as long as bRs. R forking into three branches: R1, R2+3 and R4+5. R1 and R4+5 somewhat divergent terminally; R2+3 and R4+5 arched. Forking of Rs distad of the level of M forking. Rs strong, arising from beyond the basal one-third of length of wing, bRs+dRs nearly 0.4 times the R4+5.

R1 slightly curved, relatively long (nearly 0.5 times the length of wing), slightly deflected after junction with R2+3; R2+3 slightly curved, shifted toward wing base, beyond the level of M1+2 forking. Vein R4+5 strongly arched near its midway, almost parallel with R1, but slightly oblique at apex. Stem of M completely reduced basad of crossvein m-cu, with only a short segment distad of m-cu. Stem of M forking into M1+2 and M3+4. M1+2 forking into M1 and M2 near R2+3 level. M1 arched anteriorly, M2 nearly straight.
