Gena with 2 strong setae and 4–5 smaller setulae. Acrostichal setulae in 4–6 rows. Costagial seta length unknown (broken on both sides of holotype); second costal sector shorter than third (35:40).

Posterior lobe of surstylus elongate, with apex and posterior margin heavily setose; anterobasal lobe broadly rounded and laminate, with distal triangular projection. Cercus ovoid.
