Dielis

Dielis is a New World genus of the family Scoliidae, also known as the scoliid wasps, formerly treated as a subgenus within Campsomeris.

Description and identification
Dielis are medium sized wasps that exhibit strong sexual dimorphism. The females are black with broad yellow or orange bands on the abdomen, often on the first 3 or 4 tergites. The males have yellow bands on the first 4 or 5 tergites. The setae are usually white, though in some species there is a yellowish to brownish tint. The forewing of Dielis species includes two recurrent wing veins and two submarginal cells as typical of the genera of Campsomerini, apart from Colpa.

Distribution
Species of this genus occur from Canada south to Chile and Argentina.
