Abstract

Meringosphaera mediterranea is the type species of the genus. The species is widely distributed in the polar, temperate, and tropical marine waters. For many years the systematic position of this species was unclear (the most common opinion was that the species is xanthophyte or chrysophyte alga), and its affiliation to centrohelids was clarified quite recently. In this paper, we report on the finding of M. mediterranea in the East Siberian Sea and for the first time in the Laptev Sea and provide a description of this species accompanying by LM and SEM microphotographs. Also, we summarize all available published information on the global distribution of M. mediterranea.


Keywords: Haptista, Meringosphaera, algae, centrohelid heliozoa, distribution, microscopy, morphology, protists, East Siberian Sea, Laptev Sea, Russia
