Five fish amoeba strains were selected by morphology as possible members of the genus Vexillifera Schaeffer, 1926. Phylogenetic analyses of SSU rDNA sequences revealed that 4 of these strains form a best supported clade together with Vexillifera minutissima and V. bacillipedes. Comparison of trophozoite morphology and SSU rDNA sequences identified a strain closely related to V. bacillipedes; and characteristics of another 3 strains allowed to establish 3 new species: Vexillifera multispinosa, V. fluvialis and V. tasmaniana. The enlargement of dataset of Vexillifera SSU rDNA sequences enables us to doubt the identification of ATCC strain 50883 designated as V. armata. Since sequence of this strain branched in our analysis in a distant phylogenetic position within Korotnevela and Neoparamoeba clade, its Vexillifera origin is called in question. The same applies to the newly generated sequence of the type strain of V. expectata, previously characterised by its morphology only.
