N2 - Apicomplexans form a large and diverse group of unicellular parasites inhabiting invertebrates and vertebrates. Gregarines are mostly extracellular apicomplexan parasites that occur in the intestine, coelom and reproductive organs of marine, freshwater and terrestrial invertebrates. Most gregarines infecting the intestine of marine invertebrates have been described within the family Lecudinidae and the type genus Lecudina. The diversity of these ‘marine’ parasites is vast and still poorly understood. Moreover the family Lecudinidae is probably a taxonomic mixture; some species considered to be ‘lecudinids’ may well belong to other families of aseptate eugregarines. The genus Polyrabdina (=Polyrhabdina by Caullery & Mesnil, 1914, presently accepted) was established by Mingazzini, 1891 for Gregarina spionis Kolliker, 1848 from polychaetes Malacoceros fuliginosus. To date this genus comprises six species of parasites inhabiting marine worms of the family Spionidae; Polyrhabdina spionis is the type species. The i
