Pleuron mixture of light and dark brown. Legs yellowish­brown, except apex of hind femur with round dark brown macula. Forefemur slightly expanded on apical one­half. Combined length of foretarsomeres approximately 0.8 length of foretibia. Foretarsal claws large, recurved, with large basal lobe. Mean costal width 0.50 wing length, range 0.49–0.51. Halter yellow. Abdominal tergites black, anteriorly with silver pollinosity. Venter of abdomen gray. Ovipositor dark brown; elongate, flat dorsally, curved dorsally, in dorsal view clavate subapically; with dense short setae, especially dorsally.
