above anal fin; gill cover significantly darker than rest of body below lateral band; distinct preorbital, postorbital, and cheek stripes; no black markings on ventral surface of head or body apart from short narrow grey pre-anal stripe, occasionally visible in very large specimens only (Ref. 94125). |
