Diagnosis (adapted from Shaw (1985)): 3RSb reaching apex of the wing, or at least marginal cell longer than stigma; tergum 1 subsessile, basally half as wide as propodeum ( Fig. 19 ); laterope present as deep basal pit; petiolar spiracles anterior to middle; lateral fold of tergum 2 absent; mesopleural sculpture variable, coarse to smooth; precoxal sulcus variable, distinct to absent; mesonotum grading into scutellar sulcus, no distinct suture; scutellar disc punctate smooth; vein (RS+M) variable, entirely present to absent, sometimes only partly present apically ( Figs 21–25 ); M+CU either reduced into a short stub or completely absent; dorsope absent; suture between laterotergites 2+3 absent; ovipositor broad and curved ( Fig. 6 ); ovipositor sheaths densely setose; vein M either reduced into a short stub or completely absent; mesonotal sculpture variable, notauli sculptured to totally smooth, sometimes notauli only partly present anteriorly; pronotum variable, sculptured to smooth; scutellar sulcus crosscarinae variable, distinct to totally smooth.
