What is "stenodynerus"

Stenodynerus is a rather large genus of potter wasps whose distribution spans the Nearctic, Palearctic, Oriental and Neotropical regions. Most of its species lack a transverse carina on the first metasomal tergum. A pair of medial pits on the anterior face of the pronotum and the expansion of the tegulae put this genus close to genera as Parancistrocerus, Hypancistrocerus and Eustenancistrocerus.
