Astyanax asuncionensis Géry, 1972

Astyanax asuncionensis is a small species of freshwater fish described in 1972 from Asunción, the capital of Paraguay in South America. Its specific epithet is in reference to this. Currently, its range is known to encompass areas of not just Paraguay but also Argentina and Brazil. It is an adaptable, omnivorous species that easily lives in sympatry with various congeners.

There are several congeners to which A. asuncionensis is closely related, including Astyanax altiparanae and Astyanax abramis. Genetic testing has differentiated the species, though A. altiparanae is suspected to form a species complex with A. asuncionensis. These genetic similarities accompany various morphological similarities that make it difficult to visually distinguish A. asuncionensis from congeners upon casual examination.
