Short Description
Diagnosis: Disc diamond-shaped (rhomboid). Snout elongated, preorbital distance 35.7-37.7% in DW. Lower lip outline with a dark, well-defined band. Shoulder region to base of tail with a row of small tubercles along the midline of disc, tubercles somewhat randomly distributed. Posterior margin of the pectoral fins uniformly rounded; of the triangular-shaped pelvic fins, almost straight or slightly sinuous, with its tips exceeding posterior margin of disc. Dorsal caudal keel absent in the holotype, vestigial in the 2 paratypes (Ref. 56441). Diet: Colares Island region, Pará, Brazil (data base: 47 specimens): Crustaceans were the predominant food item (%IRI = 58) and included species belonging to the Portunidae (crabs), Alpheidae, Penaeidae e Palaemonidae (shrimps) families. Teleosts had an intermediate level of importance (%IRI = 42) in the diet of this species and corresponded to gobiid (Perciformes) species. Annelids and molluscs were rare food items. [15498].
