New Stands of Species of the Paramecium aurelia Complex (Ciliophora, Protista) in Europe, Asia, and Oceania (Guam)

New stands of species of the Paramecium aurelia complex in Europe (Poland - P. novaurelia, Spain - P. primaurelia), Asia (Russia, Altay - P. biaurelia, P. novaurelia and Kamchatka - P. pentaurelia, Iran - P. primaurelia), and Oceania (Guam island - P. octaurelia) are presented in the paper. Especially interesting is a stand on Guam, the largest and southernmost island in the Marianas Archipelago (Australia with Oceania), as well as a stand in Ispahan, Iran. Both regions were sampled for the first time for the presence of the P. aurelia spp. Results of the paper are in agreement with the opinion that some species of the P. aurelia complex are cosmopolitan (as P. primaurelia and P. biaurelia), other species such as P. octaurelia seem limited to tropical or subtropical regions, and P. novaurelia can also be found outside of Europe. Besides the P. aurelia spp., other species of Paramecium genus were identified in the collected water samples, i.e. P. caudatum (Ispahan, Iran and Bia³owie¿a, Poland); P. polycaryum (Guam), and P. multimicronucleatum-like (Guam).
