Espinhos dorsais (total) : 2; Raios dorsais (total) : 6 - 7; Espinhos anais: 0; Raios anais : 14 - 15; Vértebras: 44 - 46. Diagnosis: Ancharius fuscus is distinguished from other species of Anchariidae by the following unique characters: shorter snout, 40.1-45.8% of head length vs. 47.1-54.3; longer maxillary barbels, reaching to midpoint of pectoral-fin base vs. not reaching to base of pectoral spine; pectoral spine serrated along its entire posterior margin; vs. along distal half only; and purplish-gray colouration vs. highly mottled dark gray and cream, lead gray or mottled brownish-gray (Ref. 56142). It further differs from Ancharius griseus in having a shorter dorsal-fin spine, 14.6-22.6% of standard length vs. 22.9-24.3%; and larger eye, 11.4-15.4% of head length vs. 9.3-10.1% (Ref. 56142).
Ancharius fuscus is restricted to the middle to upper reaches of several river basins of the eastern coast of Madagascar and to habitats that are not highly degraded (Ref. 56142).
