Small tenpin-shaped species, 120–125 µm in total body length. Cephalion present, pleuria absent. Hypostomion present. Furca forcipate, 30 µm in length with thin adhesive tubes that are terminally knobbed. Proximal parts of furcal branches covered by round smooth scales. Dorsal surface covered by 5–7 columns of smooth scales. One pair of parafurcal spines present and reach halfway down the length of the furcal branches. Ventrolateral scales with short simple spine distributed in 2–3 columns on either side of the body. Ventral interciliary area apparently naked or with poorly developed keels. A pair of ventral terminal scales present. Pharynx with slight terminal swellings, 30–32 µm in length.
