Holotype species: Hematodinium perezii Chatton & Poisson

Original publication and holotype designation: Chatton, E. & Poisson, R. (1930). Sur l'existence, dans le sang des craes, de Péridiniens parasites: Hematodinium perezi n. g., n. sp. (Syndinidae). Comptes Rendus Hebdomadaires des Séances et Mémoires de la Société de Biologie et des ses Filiales et Associées 105: 553-557.

Taxonomic status: currently recognized as a distinct genus.

Description: Marine plasmodial parasite without chloroplasts in the hemocoel of Crustacea. In contrast to Syndinium Chatton, forming one large plasmodium occupying more or less the whole hemocoel of the host, but producing secondarily by fragmentation smaller plasmodia, Hematodinium produces primarily many small plasmodia up to 150 µm long. Nuclei are of typical Syndinium-type with 5 V-shaped chromosomes. Exact mode of dinospore formation and of its morphology so far unknown. Delimitation from Syndinium is difficult, and some reports may be confused with Hematodinium to which Syndinium is closely related or congeneric. May be the parasite causing the economically important "Bitter Crab Disease". For these parasitic dinoflagellates, spores are described. Endoparasites of marine Crustacea (Decapoda and perhaps Amphipoda) of the North Atlantic and the Mediterranean, perhaps the cause of Bitter Crab Disease in the Pacific.

Numbers of names and species: There are 2 species names in the database at present, of which 2 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
