de Oliveira, RR, J Zuanon, CH Zawadzki & LR Py-Daniel, 2015. Ancistrus maximus, a new species of red-dotted armored catfish from rio Branco, Roraima State, Brazilian Amazon (Siluriformes: Loricariidae). Ichthyological Exploration of Freshwaters 26: 73-82.
Abstract
Ancistrus maximus, new species, is described from the igarapé Macoari, rio Branco drainage, Roraima State, Brazilian Amazon. It is distinguished from all congeners, except A. dolichopterus, A. fulvus and A. latifrons, by having more branched rays in the dorsal fin (8 vs. 7). Ancistrus maximus is distinguished from A. dolichopterus, A. fulvus and A. latifrons by color pattern and by the combination of various characters. Ancistrus maximus is remarkable in its very large body size, attaining 200 mm SL, an uncommon size for species of the genus reached otherwise only by A. chagresi and A. centrolepis.
