摘要: We redescribe Paramecium chlorelligerum, a forgotten species, which Kahl (Tierwelt Dtl., 1935, 30:651) briefly but precisely described in the addendum to his ciliate monographs as with symbiotic green algae. The redescription is based on classical morphological methods and analysis of small subunit (SSU) rDNA. Morphologically, P. chlorelligerum differs from (C.) bursaria, second species genus, by having special swimming shape, length caudal cilia, size micronucleus, algae, contractile vacuoles (with collecting vesicles vs. canals), number excretory pores/contractile vacuole (1 2-3). molecular investigations show that forms distinct branch distant (Chloroparamecium) bursaria clade. Thus, we classify new subgenus: (Viridoparamecium) chlorelligerum. alga belongs little-known genus Meyerella, yet recorded only plankton North American lake.
