Diagnosis. Tibia lacking profuse setae equal to, or longer than, the tibial spur. Legs are completely yellow, except for last tarsal segment being brown (see Fig. 2 c). The thorax ranges from light to dark brown. The wings have a diffuse brown marking apically, which extends from cell R1 to halfway through cell R4+5 (see Fig. 3 c). The abdomen is completely black.
