This species has a long and slender body with parallel edges. The three–lobed head has a wide cephalion and large hypopleuria, but no epipleuria. The hypostomium is elliptical in shape. On the head there are two pairs of cephalic ciliary tufts. The mouth ring is situated ventrally. The pharynx has slight dilatations at the ends. The furca is massive and thick, with very short adhesive tubes. The branches of the furca are parallel and do not part outwards. On the furca base there is a posterior pair of dorsal sensory bristles. The posterior sensory bristles are anchored at small papillae, situated near the furca base. The body surface is not covered with cuticular structures visible in the light microscope. On the ventral side there are two longitudinal ciliary bands with very long cila. Ocellar granules absent.
