It bears four thick spines with three groups of 4–6 thin spines interspersed, and two thin spines on each side between the thick lateral spines and the opening of the belt, all arising from the distal ring in a single row.

, the bursa copulatrix of some specimens has a pseudocuticle formed by the basilar walls of the epithelium, which was not observed in our material. On the other hand, a sinuosity was observed in the peduncle of the bursa, and a pair of lateral projections in the main region of the bursa (figure 5C). These were very evident in our material, but are not mentioned in the original description of this species.
