[ref. ID; 4714]
The genus Cercomonas Dujardin (syn. Cercobodo Krassilschik) includes colourless flagellates having two heterodynamic flagella and a single nucleus. They regularly form pseudopodia which serve for locomotion and food ingestion. Unlike the amoebo-flagellates of the order Schizopyrenida, the representatives of Cercomonas do not shed their flagella during the amoeboid stage and do not form pseudopodia of the "limax" type.
