Class SYNDINIOPHYCEAE class nov. (ref. ID; 3731 original paper)
Diagnosis (Latin); Dinoflagellata quae up parasitici intracellulares in invertebratis marinis vivunt, et quae unicum nucleum 4-10 chromasomata forma litterae "V" continentem habunt. Apex horum chromosomatum membranae nucleari adhaeret. Chromosomata proteios basicos, qui modo histochemico detegi possunt, continent. Mitosis implicat centriolos necnon unum canalem microtubulos continentes, qui nucleum transfigit. Cellulae mobiles nonthecatae biflagellataeque.
Typus; Syndiniales ord. nov.
Comments; I propose the new class Syndiniophyceae, which is distinguished from the Dinophyceae in the following features: (a) low chromosome numbers (4-10); (b) V-shaped chromosomes; (c) chromosomes containing a sufficient quantity of histochemically detectable basic proteins; (d) possession of centrioles associated with mitosis; (e) intracellular parasitism as a mode of nutrition; and (f) lack of cell cover containing thecal plates. Syndiniales is proposed as a replacement for the order Coccidiniales Chatton & Biecheler, 1934, since there is some doubt as to whether Coccidinium exists. Loeblich & Loeblich (1973) noted that one of the figures attributed to Coccidinium is in reality the symbiote or eukaryotic nucleus to Peridinium balticum. The identity of the organisms represented in the other figures is unclear. (ref. ID; 3731)
