Ornithocheiriformes (Pterosauria, Pterodactyloidea, Lanceodontia) is the clade comprising all species closer to Ornithocheirus simus than Istiodactylus latidens. This group includes, in a broad sense, all forms usually regarded as close relatives of Ornithocheirus simus, Coloborhynchus clavirostris, and/or Anhanguera blittersdorffi. This group suffers from complex and controversial nomenclatorial problems since the early days of pterosaur science. The recent adherence to the PhyloCode in pterosaur nomenclatorial works provides a basis for a solid standardization of clade names and definitions, even though their stability may sometimes be sensitive to differing phylogenetic hypotheses. The present work aims at integrating/conciliating the convoluted nomenclature of Ornithocheiriformes into both the International Code of Zoological Nomenclature (ICZN) and the International Code of Phylogenetic Nomenclature (PhyloCode), to prevent equivalent clades from having different names under each Code, especially when registered definitions are applied to distinct phylogenetic hypotheses.
