Here we describe a microaerophilic genus and species of amoeboflagellate isolated from a nearshore marine site off the coast at Plymouth, Massachusetts: Subulatomonas tetraspora nov. gen. nov. sp. This taxon is closely related to Breviata anathema based on both microscopical features and phylogenetic analyses of sequences of three genes: SSU-rDNA, actin, and alpha-tubulin. However, Subulatomonas tetraspora nov. gen. nov. sp. and B. anathema are morphologically distinctive, differ by 14.9% at their ssu-rDNA locus, and were isolated from marine and ?slightly brackish? environments, respectively. Phylogenetic analyses of these two taxa plus closely related sequences from environmental surveys provide support for a novel clade of eukaryotes that is distinct from the major clades including the Opisthokonta, Excavata, Amoebozoa and ?SAR? (Stramenopile, Alveolate, Rhizaria).} }
