A New Genus and Species of a Minute Suckermouth Armored Catfish
(Siluriformes: Loricariidae) from the Rio Tocantins Drainage, Central
Brazil: The Smallest Known Loricariid Catfish
Alexandre C. Ribeiro, Flavio C. T. Lima, and Edson H. L. Pereira
Copeia, No. 4: 637 - 647.
Nannoplecostomus eleonorae, a new genus and species of a miniature suckermouth armored catfish, is described based on
specimens collected from the karst region of Sao Domingos, upper Rio Tocantins basin, Goias State, central Brazil. The
new genus and species can be diagnosed among loricariids by presenting a unique reductive pattern of lateral dermal
plates, with most of the body covered by only three series of plates (viz., dorsal, mid-ventral, and ventral). Based on the
available published phylogenetic studies for the family, we provisionally consider Nannoplecostomus eleonorae as being
an incertae sedis taxon within Loricariidae. Achieving a maximum standard length of 22.2 mm SL, Nannoplecostomus
eleonorae is the smallest known loricariid catfish, and a list of the remaining smallest loricariids is provided.
