Two new species of Leporinus Agassiz, 1829 from Araguaia-Tocantins system, Amazon basin, Brazil (Ostariophysi, Anostomidae)

Two new species of genus Leporinus from the Araguaia-Tocantins system, Amazon, Brazil, are described. Leporinus unitaeniatus n. sp. is distinguished from the remaining species of this genus by the presence of a conspicuous longitudinal dark brown bar along the lateral line on the flanks, and Leporin...

Leporinus unitaeniatus n. sp. is distinguished from the remaining species of this genus by the presence of a conspicuous longitudinal dark brown bar along the lateral line on the flanks, and Leporinus geminis n. sp. is distinguished by an inconspicuous dark bar combined with three large and vertically elongated brown blotches on the trunk; the first on the dorsal fin region, the second anterior to the adipose fin and the third on the caudal peduncle. Both are medium-sized species of the genus (up to 150 mm SL) and share the following combination of meristic characters: 4 teeth on each premaxillary and dentary; 40-43 scales in the lateral line, 6/I/5 scales on the transversal line, and 16 series of scales around the caudal peduncle. L. unitaeniatus n. sp. has a sub-terminal mouth and tooth series formed by incisive-like elongated teeth frontally turned and with only a straight cutting edge decreasing in size like the steps of stairs from the teeth pair of symphysis. Leporinus geminis n. sp. has a sub-inferior mouth and the tooth series shaped by large incisive-like teeth forming an arched cutting edge, decreasing in size from the symphysal pair of teeth.Volume 69, Número 1, Pags. 109-116Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessAnostomidaeLeporinusOstariophysiPiscesAnimalsBrasilClassificationFishHistologyRiverAnimalBrasilFishesRiversTwo new species of Leporinus Agassiz, 1829 from Araguaia-Tocantins system, Amazon basin, Brazil (Ostariophysi, Anostomidae)Duas novas espécies de Leporinus Agassiz, 1829 do sistema hidrográfico Araguaia-Tocantins, Amazônia, Brasil (Ostariophysi, Anostomidae)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleRevista Brasileira de Biologiaporreponame:Repositório Institucional do INPAinstname:Instituto Nacional de Pesquisas da Amazônia (INPA)instacron:INPAGaravello, Julío CésarSantos, G.
