Aequidens is a South American genus of fish in the family Cichlidae. Many species formerly placed in this genus have been reallocated to other genera such as Andinoacara, Bujurquina, Laetacara, Tahuantinsuyoa, Krobia, Rondonacara and Cleithracara.[1] As presently defined, Aequidens is largely restricted to the Amazon Basin, Orinoco Basin and river basins in The Guianas. The only exceptions are A. plagiozonatus which also occurs in the Paraná Basin, and A. tetramerus which also occurs in the Parnaíba River.

Species

There are currently 16 recognized species in this genus:[2]
