Abstract
The thecate dinoflagellates of the family Oxytoxaceae are reviewed. The synonymy of the species of the genera Oxytoxum and Corythodinium (= Pyrgidium) is analysed in order to facilitate the identifications. Seventy-one species have been placed in the genus Oxytoxum. Only twentynine species are accepted after a comparison of the original descriptions and recent observations from Mediterranean, Atlantic and Pacific Oceans. Most of the remaining species are considered synonyms of other species of Oxytoxum or placed in Corythodinium or other genera. Species such as O. gladiolus or O. schauinslandii are resucitated as senior synonyms of species more commonly reported in the literature. From the sixteen species placed in Corythodinium, only C. carinatum and C. michaelsarsii are considered synonyms of other congeneric species. Six taxa initially described as species of Oxytoxum are transferred into Corythodinium. The new combinations are C. brunellii comb. nov., C. milneri comb. nov., C. mucronatum comb. nov., C. radiosum comb. nov., C. robustum comb. nov. and C. strophalatum comb. nov. A new species is proposed, C. hasleae sp. nov., for a taxon misidentified as O. milneri.
