Members of this genus are small, with a very short proboscis, and have 2 submarginal cells. The body is bare shining black, and the legs are largely without spines or hairs. The posterior margins of some of the tergites are outlined in yellow. The genus was formerly included in the subfamily Bombyliinae. We are unaware of specific records from the region, but specimens have been attributed to “Arizona” suggesting the following two widespread Western species are possible:
