The type locality of the species is the area directly upstream and downstream of a 30 m (98 ft) high waterfall. This environment is a 10 m (33 ft) wide river channel with shallow, clear water and a substrate composed of gravel, pebbles, boulders, bedrock, and iron-rich sand. The species reaches 4 cm (1.6 inches) in standard length. It was described in 2012 as part of a taxonomic review of members of the loricariid tribe Harttiini native to the Guianas.
