species by its yellow body without dark areas on the metasomal tergites (Figs 1-4), and from all yellow Neotropical species by the keel on the first metasomal tergite being strongly angulate in lateral view (Figs 1, 15 arrow) (weaker or not angulate in the Neotropical species). Although this species morphologically much resembles
