Etymology: Parananochromis: Greek, para = the side of + Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); brevirostris: From the Latin brevis, short and rostrum, beak or snout, in reference to the short, rounded snout of the species (Ref. 50579).
Environment: milieu / climate zone / depth range / distribution range

Africa: Ivindo and Ogowe drainages in Gabon (Ref. 50579, 81260, 97361). Reports from the Ntem River (Ref. 50579, 81260) are misidentifications for Parananochromis elobatus (Ref. 97361).
