Diagnosis: Living animals up to 30 mm in length. Body elongated, oval, reduced sensory bristles, not visible to the naked eye; cephalic shield well differentiated from the body, with frontal elevation, crest-like (autapomorphy); eyes frontal, conspicuous, inserted in small circular unpigmented periocular areas (autapomorphy); posterior shield with symmetrical, rounded, short caudal lobes (Figs 3O, 4). Shell variable, convex-dilated with open whorl (Fig. 5B), convex-concealed (Fig. 5E) or spoon-shaped with prolonged and semi-wide open whorl (Fig. 5I). Buccal bulb tubular, long, muscular (autapomorphy). Penial papilla conical; prostate formed by a long narrow duct, not coiled (autapomorphy) (Rudman, 1972a; Gosliner, 1980).
