description
Astyanax paris, other Astyanax? Astyanax paris is rather dissimilar to other species of Astyanax in the lacking of secondary sexual bony hooks on the fins of adult males and the possession of several maxillary teeth. However, these features are not exclusive of this species within Astyanax, and the position of this species in a different node than the type species of the genus should be further tested. According to this results, A. paris should be transferred to a new genus.
