Chromidina elegans is a species of parasitic ciliates. It is a parasite of the cuttlefish Sepia elegans.
Taxonomy Chromidina elegans was first described from specimen collected from off Naples, Italy, by Foettinger in 1881, bearing the name Benedenia elegans.Foettinger A. 1881. Recherches sur quelques Infusoires nouveaux parasites des Céphalopodes. Archives de Biologie, 2, 345-378. It was reassigned to the Genus Chromidina by Gonder, in 1905.Gonder R. 1905. Beiträge zur Kenntnis der Kernverhältnisse bei den in Cephalopoden schmarotzenden Infusorien. Archiv für Protistenkunde, 5, 240-262.
The species was first redescribed by Chatton & Lwoff in 1935.Chatton E, Lwoff A. 1935. Les Ciliés Apostomes. Morphologie, cytologie, éthologie, évolution, systématique. Première partie. Aperçu historique et général. Étude monographique des genres et des espèces. Archives de Zoologie Expérimentale et Générale, 77, 1-453. and again redescribed in 2016 based on material in the collections of the Muséum National d'Histoire Naturelle in Paris.
