males lack an apical pile brush on the profemur which is dorsoventrally flattened. The pro- and mesolegs are orange and with a darker area on the dorsal side of the femur. The probasitarsus is laterally expanded and has some long orange pile. The large yellow maculae on the abdomen lack short, black spines on the posterior edges. Scutum and scutellum are entirely yellow pilose. The male of this species cannot be confused with any other species by the lateral lobe on the probasitarsus. Females have a nearly black abdomen with a pair of vague lateral maculae on tergites II and III. The female of
