Genus of fishes
Aequidens is a genus of fish in the family Cichlidae found in South America . Formerly a wastebasket genus , 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 .[ 1]
Many species formerly placed in this genus have been reallocated to other genera such as Andinoacara , Bujurquina , Cleithracara , Krobia , Laetacara , Rondonacara and Tahuantinsuyoa .[ 2]
There are currently 18 recognized species in this genus:[ 3] [ 4] [ 5] [ 6]
