According to FishBase there are nine genera in this family, but a molecular study in 2011 showed that one of these (marked with number sign# in list) should be subsumed into Hypopygus, and a comprehensive molecular study from 2015 showed that two genera (marked with stars* in list) traditionally placed here belong in Rhamphichthyidae.
