Morphology and phylogeny of the centrohelid heliozoans Raphidocystidae and their ability to consume cyanobacteria.

ABSTRACT: The centrohelid family Raphidocystidae is a large group of heliozoans whose morphology and biology are poorly understood and whose taxonomy and phylogenetic relationships are currently confusing. Here, we report the results of a study of clonal cultures of raphidocystids belonging to the species Raphidocystis tubifera, R. ambigua, R. marginata and R. symmetrica. The cells were examined using light microscopy as well as scanning and transmission electron microscopy. New data on the morphology of the studied species were obtained and compared with other representatives of Raphidocystidae. For the first time, R. ambigua and R. symmetrica are reported for Kazakhstan and China, respectively. Cases of taxonomic confusion within Raphidocystidae have been detected and discussed.
