The purpose of this application, under Article 75.6 of the Code, is to conserve the specific names of Anolis chlorocyanus Duméril & Bibron, 1837 and Anolis coelestinus Cope, 1862 in their accustomed usages. The syntypes of the former species are conspecific with the only available syntype of the latter; however, for about 85 years the name A. coelestinus has been applied to the species represented by these types. For the same period of time the name A. chlorocyanus has been consistently applied to another equally well-known taxonomic species. It is proposed that the Commission use its plenary power to set aside the type status of the syntypes of A. chlorocyanus in order to stabilize the current and long-established usage of the names A. chlorocyanus and A. coelestinus. It is further proposed that the specimen SMF 97845 be designated as the neotype of A. chlorocyanus Duméril & Bibron 1837. SMF 97845 is an adult male from El Limón, Province Samaná, Dominican Republic, that represents the taxonomic species traditionally referred to as A. chlorocyanus.
