The peristomium and segment 3 have elongate, semi-circular lateral lobes, segments 2 and 4 each have small lobes, segments 5 and 6 have very small lobes inserted between the neuropodium and ventral pad. Individuals of the new species have 17 pairs of notopodia from segment 4 and conical nephridial papillae on segments 6 and 7.
