Free-living heterotrophic flagellates from bays of Sevastopol (the Black Sea littoral)

摘要

Species composition and morphology of heterotrophic flagellates in littoral andsupralittoral zones of the Black Sea (southwestern part of the Crimea) were studiedin September 2017. A total of 77 species and forms of heterotrophic flagellates wereencountered in this survey, 35 of them are new records for the Black Sea, and one,Oscillata sevastopoliensis gen. et sp. n., was described for the first time. The mostfrequent were Metromonas simplex and Neobodo designis (observed in 14 samples),Lentomonas corrugata (13 samples), Amastigomonas mutabilis and Petalomonas poosilla(10 samples). Species diversity in the present study was higher in comparison withthe data obtained in May 2017 in the same region. Micrographs and morphologicaldescriptions of 20 species (Ministeria vibrans, Salpingoeca oblonga, Savillea parva,Stephanoeca apheles, S. cupula, Volkanus costatus, Cafeteria ligulifera, Paraphysomonaslucasi, Pteridomonas danica, Colponema marisrubri, Ovaloplaca salina, Clautriaviacavus, Dinema platysomum, Lentomonas corrugata, Notosolenus stutulum, N.tamanduensis, Hemistasia amylophagus, H. phaeocysticola, Heterochromonas opaca,and Oscillata sevastopoliensis gen. et sp. n.) are given.
