Diagnosis. It belongs to the annulicornis species-group, and can be separated from other species within that group based on the combination of ovipositor sheaths length, T2 mostly longitudinally striate (except for small smooth central area), propodeum mostly smooth (with only median longitudinal carina), and scutoscutellar sulcus with 6 impressed pits.
