Members of the currently recognized acanthopterygian order Pegasiformes have an unusual feeding mechanism in which enlarged maxillovomerine cartilages are closely associated with the maxillae, premaxillae and dentaries forming a highly protrusible mouth. This is a unique mechanism among living teleosts, but apparently present in the Lower Eocene Ramphosidae, currently placed among the aulostomoid gasterosteiforms. This and other evidence support a gasterosteiform ancestry for the Pegasidae. The Pegasiformes are synonymized with the Gasterosteiformes. The fossil Ramphosidae are resurrected from the synonymy of the Macrorhamphosidae and placed with the Pegasidae in a new superfamily, the Pegasoidea. The Pegasoidea are proposed as the primitive sister-group of the Solenostomidae and Syngnathidae. The Solenostomidae and Syngnathidae are included in a new superfamily, the Syngnathoidea, which together with the Pegasoidea form the primitive sister-group of the Macrorhamphosidae, Centriscidae, Aulostomidae and Fistulariidae.
