abstract = "We have found a new free-living amoeba species named Balamuthia spinosa n. sp. (Amoebozoa, Discosea) in the bottom sediments of the brackish-water Niv{\aa} Bay (Baltic Sea, The Sound). This species resembles members of the genus Stygamoeba morphologically and was (mis)identified as belonging to this genus during the initial investigation. However, SSU rRNA gene data show that it robustly groups with Balamuthia mandrillaris sequence among Acanthopodida and represents a new species of the genus Balamuthia. Fragments of Legionella pneumophila genome were found among the NGS contigs obtained from B. spinosa n. sp., suggesting that this species may be a vector of Legionella in the environment. We discuss a remarkable morphological and ultrastructural similarity between the genus Balamuthia and the genus Stygamoeba. In addition, our phylogenetic analysis based on the SSU rRNA gene sequences revealed a close relationship between the genera Stygamoeba and Vermistella. It is one more confirmation of the order Stygamoebida, which was formed basing on the morphological evidence. The position of these branches close to Thecamoebida clade is congruent with current phylogenomic data.",
