" We describe a new Geophagus from the Berbice River of Guyana, bringing the total number of described species in the genus to 19, and of Guianese species to six. Geophagus crocatus, new species, is distinguished from all species of Geophagus outside of the G. surinamensis group by the presence of an incomplete suborbital stripe (vs. complete), and the presence of six lateral bars, with bars 2 and 3 slightly sloping toward each other and fusing dorsally at the base of the dorsal fin. Geophagus crocatus is the only Geophagus species known from the Berbice River, and it is present above and below the Itabru Falls "
