This suborder is not supported by new molecular and DNA sequence evidence. Morphological characters that were used to define the group (pharyngeal jaws; &c.) are probably homoplasic, i.e. do not have a common evolutionary origin but evolved independently. See Wainwright et al., 2012 among others. Cichlidae, Embiotocidae, Pomacentridae removed from Labroidei by Wainwright et al. 2012.
