Mikrogeophagus maculicauda, a new dwarf cichlid (Teleostei: Cichlidae) from the eastern drainage of the upper Rio Guaporé, Brazil

Wolfgang STAECK, Felipe Polivanov OTTONI, Ingo SCHINDLER

Abstract

Mikrogeophagus maculicauda sp. n. is described from the upper Rio Guaporé drainage in the Estado Mato Grosso in Brazil. It can be distinguished from the congeners by the presence of the following characteristics: a large rectangular or square dark spot extending almost over the entire caudal peduncle, a greenish metallic sheen on the sides of the body, and in adult males very long filiform extensions of the posterior soft dorsal fin and the marginal rays of both the upper and the ventral lobe of the caudal fin.

Keywords
