Abstract
Relationships among species of Rivulus endemic to the Brazilian Amazonas river basin are evaluated through an analysis of morphological characters, including terminal taxa representative of all Rivulus lineages. Based on the present morphological phylogeny and previous molecular analyses, seven subgenera are recognized: Rivulus, Cynodonichthys, Anablepsoides, Benirivulus n. subgen., Laimosemion, Owiyeye n. subgen., and Melanorivulus n. subgen. Benirivulus is diagnosed by a unique colour pattern and includes a single species, R. beniensis, from the rio Madeira drainage; Owiyeye is diagnosed by the absence of dermosphenotic, a derived pattern of frontal ...
