Antennal segment 1 is not enlarged, segment 2 is produced at an outer angle and the produced tip is acute. Segment 6 and the style (consisting of segments 7 and 8) are not unusually long. The thorax lacks stout setae, though the pronotum has 2 pairs of prominent epimeral setae. Mesoscutum has anterior scalloped striae. Males are brachypterous. Abdominal tergites lack scallops, and sternites have transverse striae, except for posterior line, which is scalloped (Stannard, 1968).
