“…rivularis Lütken, 1875 (Oliveira, 2021), was formally part of the genus Astyanax (Terán et al, 2020). Both genera have been used in several works involving geometric morphometry in recent years (Aguilar‐Medrano, 2013; Alves et al, 2020; Castro et al, 2014, 2015; Delariva & Neves, 2020; Ornelas‐García et al, 2014; Perazzo et al, 2019; Powers et al, 2017; Rocha et al, 2019; Santos & Araújo, 2015; da Silva et al, 2021).…”

The genus Psalidodon, in turn, has shown great potential in studies involving the variation of form associated with genetic characteristics (Alves et al., 2020;Rocha et al., 2019). Rocha et al. (2019) demonstrated the correspondence between molecular data and body shape variation in different mitochondrial lineages of P. rivularis and P. paranae Eigenmann, 1914. The study also reinforced the taxonomic validity between the two species, both through molecular and morphometric data.Approaches involving cytogenetic markers together with geometric morphometry were used by Castro et al.

“…The high diversity of Neotropical freshwater fish has been challenging to classify (DoNascimiento et al., 2017 ; Mirande, 2019 ; Silva et al., 2020 ). Although the complex biogeographic patterns of some of these taxa (extending over vast continental areas) have been the focus of much research recently, Characidae, which have small body size and relatively uniform morphology, are still poorly understood.…”

To date, the taxonomic status and phylogenetic affinities within Hyphessobrycon, even among other genera in Characidae, remain unclear. Here, we determined five new mitochondrial genomes (mitogenomes) of Hyphessobrycon species (H. elachys, H. flammeus, H. pulchripinnis, H. roseus, and H. sweglesi). The mitogenomes were all classical circular structures, with lengths ranging from 16,008 to 17,224 bp. The type of constitutive genes and direction of the coding strand that appeared in the mitogenomes were identical to those of other species in Characidae. The highest value of the Ka/Ks ratio within 13 protein‐coding genes (PCGs) was found in ND2 with 0.83, suggesting that they were subject to purifying selection in the Hyphessobrycon genus. Comparison of the control region sequences among seven Hyphessobrycon fish revealed that repeat units differ in length and copy number across different species, which led to sharp differences in mitogenome sizes. Phylogenetic trees based on the 13 PCGs did not support taxonomic relationships, as the Hyphessobrycon fish mixed with those from other genera. These data were combined to explore higher level relationships within Characidae and could aid in the understanding of the evolution of this group.
