Ventral coronal teeth absent, fully developed ventral transverse longitudinal carina absent. Antennomeres 4 and 5 not conspicuously shortened, maxillary palp elongate, five-segmented. Median mesoscutal sulcus at most developed for a short distance anteriorly, notauli absent, mesoscutellum triangular, acute, raised compared to surrounding sclerites. Forewing vein 1r arises from approximately middle of pterostigma; vein 1r-Rs well developed, elongate, discal cell rectangular, proximal part not broader than distal part. Ovipositor internalized, extending into thorax, profurca with median groove and abdominal sterna with median apodemes for handling ovipositor.
