A new species of Gymnogeophagus Miranda Ribeiro from Uruguay (Teleostei: Cichliformes).

abstract (from publication):
We describe a new species of a substrate-brooding Gymnogeophagus, based on coloration characters. The new species can be distinguished from the remaining substrate-brooding species in the genus by the unique pigmentation of the dorsal fin which consists of light blue, diagonal stripes over a red background in the spiny section and a combination of round, elliptic, and elongated bright blue spots over a red background in the soft section. It can be further distinguished from all other species of Gymnogeophagus by the following combination of characters: a discontinuous bright blue band above the upper lateral line in the humeral area, light blue roundish spots over a red to orange background on the anal fin, and conspicuous bright blue horizontal bands on body. The new species inhabits a wide range of freshwater habitats in the lower rio Uruguay basin, Rio de la Plata coastal drainages and Atlantic Ocean coastal drainages in Uruguay.

distribution (from publication):
Gymnogeophagus terrapurpura is distributed from the rio Arapey (in the middle rio Uruguay basin) to all tributaries of the lower rio Uruguay basin and in the eastern coastal drainages of the Río de la Plata estuary and Atlantic Ocean in Uruguay.
