Until recently, this family contained only the genus Acestrorhynchus. However, taxonomic studies have found that the subfamilies Heterocharacinae (originally placed in the closely related Characidae) and Roestinae (originally placed in the more distantly related Cynodontidae) are actually more closely related to Acestrorhynchus, and now they are also placed in this family.
