Diagnosis
Frontal suture absent in the middle with lateral arms curved; lower frons with tentorial pits; eyes large, DE/DO = 3.1; occiput with a U-shaped carina medially; transscutal articulation with dents from anterior margin of scutellum; scutellum flattened; propodeum with median carina indicated only in anterior part; scape, femora and tibiae dark and metallic; petiole long, LP/WP = 2.1, with anterodorsal part projecting up on propodeum. Through the broken frontal suture, tentorial pits, U-shaped carina on occiput, transscutal articulation with dents, this is a very distinctive species. The missing part of median frontal suture is the same state as in absens, but ambaricus e.g. with tentorial pits, dark scape and legs, flattened scutellum.
