Geographic distribution: Coastal rivers between Paraíba do Sul and Itabapoana river basins.

Diagnosis: Astyanax giton is distinguished from its congeners in the Piraí drainage by presenting the posterior portion of pelvic fin surpassing the urogenital opening. A

gradual variation of size in dentary teeth size and higher body height (approximately 41% SL) are also distinguishable features of this species in relation to Astyanax intermedius and Astyanax sp. aff. scabripinnis ( Melo 2001a).
