Small subunit ribosomal RNA gene sequences were determined for 5 amoeba strains of the genus Neoparamoeba Page, 1987 that were isolated from gills of Scophthalmus maximus (Linnaeus, 1758). Phylogenetic analyses revealed that 2 of 5 morphologically indistinguishable strains clustered with 6 strains identified previously as N. pemaquidensis (Page, 1970). Three strains branched as a clade separated from N. pemaquidenis and N. aestuarina (Page, 1970) clades. Our analyses suggest that these 3 strains could be representatives of an independent species. In a more comprehensive eukaryotic tree, strains belonging to Neoparamoeba spp. formed a monophyletic group with a sister-group relationship to Vannella anglica Page, 1980. They did not cluster with Gymnamoebae of the families Hartmannellidae, Flabellulidae, Leptomyxidae or Amoebidae presently available in GenBank.
