This species is distinguished by the following characters: dorsal disc with a prominent mid-scapular thorn and dermal denticles which are small, spinular, partly embedded and are restricted to the snout, supraorbital, interorbital and mid-lumbar regions and midline of the tail; nasal capsules are oval, relatively broad and short; the ischiopubic bar of pelvic girdle is strongly arched with concave outer anterior margin, short angular prepelvic process and long posterior mesial process (Ref. 113541).
Body shape (shape guide): other; Cross section: flattened.
