Phylogenetic relationships of the enigmatic Carlastyanax aurocaudatus (Eigenmann) with remarks on the phylogeny of the Stevardiinae (Teleostei: Characidae)

This dataset contains the digitized treatments in Plazi based on the original journal article Mirande, Juan Marcos, Jerep, Fernando Camargo, Vanegas-Ríos, James Anyelo (2013): Phylogenetic relationships of the enigmatic Carlastyanax aurocaudatus (Eigenmann) with remarks on the phylogeny of the Stevardiinae (Teleostei: Characidae). Neotropical Ichthyology 11 (4): 747-766, DOI: 10.1590/S1679-62252013000400003, URL: scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252013000400747&lng=en&tlng=en The monotypic genus Carlastyanax Géry was defined to include Astyanax aurocaudatus, a morphologically odd species having, among other features, four teeth in the posterior premaxillary row and eight branched dorsal-fin rays.

Later on, the characters used to define Carlastyanax were considered as invalid and this genus was synonymized with Astyanax. In this paper, we include Astyanax aurocaudatus in a phylogeny of the Characidae and obtain a sister-group relationship between this species and Creagrutus, within the Stevardiinae. The resurrection of Carlastyanax as a valid genus is therefore proposed.
