Midtibiae with 5–6 spines on inner and outer margins on ventral surface. Posttibiae with 25–28 spines on inner and outer margins of dorsal surface separately, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Posterior margin of tenth abdominal tergite with a pair of posterior processes, apices rounded, slightly broadened ventrad. Cerci moderately curved upwards, inner margin of basal area with a notch, the other area of ventral surface after it enlarged inwards, with distinct edge, apices of cerci rounded.
