Resumen:
|
A compilation of the ciliated suctorian species found on marine meiobenthic nematodes as epibiont has been carried out based on published records. It included the taxonomic position of each species of ciliate epibiont, the species of basibiont nematodes, the geographic zones where they have been found and the different records of these species together with the corresponding bibliographic references. Altogether 12 suctorian species were listed. Among registered suctorian species, Thecacineta oregonensis, T. urceolata, Trematosoma rotunda, Loricophrya bosporica, L. mediterranea, L. scanica, L. sivertseni, L. spitinae and L. stresemanni are likely specific to nematodes. The species as Thecacineta calix and Limnoricus ceter were found on a variety of hosts. Representatives of the genus Thecacineta reproduce by vermigemmic budding, swarmers of which are unable to swim, and often attached close to the cloaca of the nematodes. Any regularity in localization were not observed in the representatives of genera Trematosoma and Loricophrya, which form ciliary, swimming swarmers.
