10-lip-2018 — Three new species of Geophagus from eastern Brazil are described
By Juan Miguel Artigas Azas

Three new species of Geophagus of the G. brasiliensis group, the three of them endemic to coastal rivers in eastern Brazil have been described by the Brazilian ichthyologists José L. Mattos and Wilson Costa in the journal Zoosystematics and Evolution. The species were delimited and diagnosed by a mix of both unique combinations of characters and DNA differences, the latter a novel approach in cichlid taxonomy. Geophagus rufomarginatus is known only from the middle and lower sections of the Buranhém River Basin in Bahia state, it is named after the red margin of the dorsal-fin lappets; Geophagus santosi is known only from the Rio Mariana, an isolated small coastal river of Bahia state, it is named in honor of Alexandre Clistenes Alcântara Santos, an ichthyologist friend of the authors; Geophagus multiocellus is known only from the middle section of the Rio de Contas Basin in Bahia stat, it is named after the presence of small pale blue spots with minute bright blue dots on its center on the caudal fin.
