Eyes superolateral; frontal fontanelle long and narrow; occipital fontanelle oval-shaped; head completely covered with bones; suprabranchial organ well developed; tooth plates relatively narrow; openings of secondary sensory canals regularly placed (Ref. 270).
Coloration: preserved specimens: grey, greyish-brown to dark brown on back and sides, pale brown on belly; some individuals show a marbled colour pattern; caudal and adipose fins uniformly coloured (Ref. 57129).
