NOMENCLATURE OF ENDOSYMBIOTIC DINOFLAGELLATES

Abstract
Summary: The nomenclature of symbiotic dinoflagellates harboured by animal hosts is reviewed with regard to its history and employment. Zooxanthella, Philozoon, Zoorhabdella, and Endodinium may be regarded as synonyms of Amphidinium which has priority. Gymnodinium is considered to be incorrectly employed instead of Symbiodinium when applied to S. microadriaticum. Chrysidella is illegitimate. It is proposed to reject Zooxanthella as a confusing name widely applied to taxa not including its type.
