Colouration: both in life and in preservation colouration is marbled: large irregular black blotches on a pale brown base present on back, flanks, dorsal and anal fins, and on posterior/upper side of paired fins; ventrum and lower parts of paired fins beige, as are distal parts of unpaired fins; caudal fin bears a series of pale and dark bands (Ref. 248, 81644, 101841). Never an irregular pattern of small white spots on body (Ref. 101841).
