Complete mitochondrial DNA ofHoplias intermedius(Günther, 1864) (Ostariophysi: Characiformes: Erythrinidae) [PDF]

open access: yesMitochondrial DNA Part B, 2016
Mitochondrial complete genome (mtDNA) of Hoplias intermedius, commonly known as "traírão" is presented. DNA from a muscle tissue sample was sequenced by next-generation sequencing. To corroborate the results, phylogenetic analysis was performed with MEGA6 to compare the complete mitogenome of H.

A taxonomic review of the species of CharaxScopoli, 1777 (Teleostei: Characidae: Characinae) with description of a new species from the rio Negro bearing superficial neuromasts on body scales, Amazon basin, Brazil

open access: yesNeotropical Ichthyology
The species of Charaxwere reviewed by Lucena (1987) who a little later (1989) added three new species to the genus. Examination of recently collected specimens from museum collections documented the more extensive geographic distribution for most species

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

open access: yesNeotropical Ichthyology
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
