A new species of Trichomycterus (Siluriformes: Trichomycteridae) from lagoa Feia drainage, southeastern BrazilAbstract
Trichomycterus caipora, new species, is described from rio Macabu basin, lagoa Feia drainage, serra de Macaé, southeastern Brazil. The new species is distinguished from its congeners from southern and southeastern Brazil by the combination of: the presence of nine pectoral-fin rays, caudal fin emarginated and high number of opercular and interorpecular odontodes. Ecological notes are presented and putative phylogenetic relationships and characters shared with congeners are discussed.
