Scientists from Brazil and Venezuela have described a new species of tetra in the genus Ctenobrycon from the Orinoco River drainage in Venezuela.

The description of the new species, named Ctenobrycon oliveirai by Ricardo Benine, Guilherme Lopes and Ernesto Ron, is published in a recent issue of the journal Zootaxa.
 
According to the authors, this species is readily distinguished from its congeners by the high number of series of scales above lateral line, the presence of a single humeral spot, and by morphometric differences in body depth, head length, and interorbital distance.
 
This species is named after Brazilian ichthyologist Claudio de Oliveira, who collected the type series.
