Astyanax chico is described from two tributaries of the rio San Francisco located in the northwestern part of Argentina. Astyanax chico bears hooks on all fin rays of males like A. ojiara, A. pynandi, A. stenohalinus, and A. troya. Astyanax chico is distinguished from the remaining species of the genus by the following combination of characters: one maxillary tooth with 2 to 4 cusps; teeth of inner premaxillary row expanded distally, deep dentary bearing 7 teeth decreasing in size…

A new species of Astyanax from headwater streams of southern Brazil (Characiformes: Characidae).

TLDR
The new species belongs to the A. scabripinnis species complex and differs from its congeners by a combination of characters, viz., body depth, narrow interorbital width, number of branched anal-fin rays, and absence of secondary sexual characters.

New Species of Astyanax (Ostariophysi: Characiformes: Characidae) from the Upper Rio Paraná System, Brazil

TLDR
Astyanax bockmanni differs from A. eigenmanniorum and all congeners in the combination of morphometric, meristic, and pigmentary features and details of oral dentition, and it is proposed that the species is a member of a clade within the Characidae that does not include Astyanax.
