Their third tergite is shiny black, and they have long white setae on the fourth tergite, forming a distinct band in front of the posterior margin of the tergite. Their setae give the appearance of coming to a point in the center of the third and fourth tergites. Females have a frons that is entirely silvery-white, except for a black median stripe, running from the base of their antennae to the end of the head.
