Small to medium-sized with the plesiomorphic melanin pattern. Differs from the other species with this pattern in the higher number of gill-rakers (16-18) and in the greater emphasis of the blotches along the dorsum in the overall pattern. Differs further from P. marginatus in the more posterior position of the deepest part of the body. |
