Abstract

A new species of rubbernose armored catfish, collected by the Catherwood Foundation Peruvian Amazon Expedition from the upper Huallaga River (650 m elevation) in central Peru, is described herein. This new species differs from all other described Chaetostoma species in having a conspicuously banded dorsal fin and by the combination of the following characters: presence of fleshy excrescence on posterior tip of supraoccipital, typically nine branched dorsal-fin rays, and evertible cheek plates with two to four hypertrophied odontodes.
