In the past, a number of morphologically similar genera were classified in this family. However, a 2025 phylogenetic study found the latter family to be paraphyletic as previously described, comprising a number of distantly related genera from across the Stomiiformes. Due to this, the family was redefined as containing just three species in two genera.
