Included genera

Galeichthys Valenciennes, 1840 .

Remarks

The total-evidence analysis corroborates previous morphological and molecular studies and confirms the recognition of a subfamily for the genus Galeichthys , as the sister group of all other members of the family Ariidae (Betancur-R. 2009, Marceniuk et al. 2012).
