Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 16 - 17; Raios dorsais moles (total): 7-9; Espinhos anais 3; Raios anais moles: 5 - 7; Vértebras: 24 - 25. Diagnosis: Congochromis robustus shares with all congeners the following characters: body moderately elongated; steep and rounded front profile; snout rounded; caudal fin rounded; one tubular infraorbital bone; nape and opercle scaled; cheek with 2 scale rows, at least on the posterior part (Ref. 91055). It differs from all congeners in its much larger size, 75.6 mm standard length vs. 49.5 mm in C. dimidiatus, 51.5 mm in C. pugnatus, 52.5 mm in C. sabinae and 44.7 mm in C. squamiceps; its greater cheek depth, 30.4-33.8% of head length vs. 20.1-32.0% in C. dimidiatus, 24.4-28.8% in C. pugnatus, 16.5-31.1% in C. sabinae and 24.1-32.0% in C. squamiceps; its greater snout length, 28.9-38.7% of head length vs. 16.6-27.2% in C. dimidiatus, 28.6-33.3% in C. pugnatus, 18.8-34.3% in C. sabinae and 21.5-30.4% in C. squamiceps; its smaller eye orbit diameter, 23.8-27.7% of head length vs. 28.9-35.1% in C. dimidiatus, 26.9-30.6% in C. pugnatus, 26.2-33.9% in C. sabinae and 27.1-34.8% in C. squamiceps; and its smaller postorbital length, 37.5-43.4% of head length vs. 42.6-47.4% in C. dimidiatus, 39.9-45.1% in C. pugnatus, 37.5-47.3% in C. sabinae and 40.7-46.0% in C. squamiceps (Ref. 91055).
