Laterotergites and mediotergite bare. Metepisternum broader than high. Wing: Sc meets R before M3 base. Costa ends beyond tip of R 5, more than onehalf length between tips of R 5 and M 1. Crossvein rm 0.37Χ length of R 1, and 0.6Χ length of M3 section. Base of fork of M 3+4 and CuA between levels of bases of M3 section and M 1 and M 2 fork. M 3+4 very weak. M 1 and M 2 fork campanulate. Longitudinal veins with setae, except Sc. Legs : Fore coxae with anterior setae, mid coxa with apical setae.
