Integrating Genetic and Cytogenetic Data: A Diversity Study of Astyanax and Psalidodon (Characidae) Species from the Paraná River Basin.

Abstract excerpt

Astyanax is one of the most specious fish groups in the Neotropical region, with many cryptic species, which represents a challenge for correct identification through traditional taxonomic methods. Psalidodon is a recently resurrected genus group of species previously belonging to Astyanax, specifically those with extensive chromosomal variation of the A. scabripinnis and fasciatus complexes. In the present...
