A new species of Leptomyxida, named Rhizamoeba neglecta was found during studies of the amoeba fauna of the inner Lake Leshevoe located at Valamo archipelago (The Lake Ladoga, North-Western Russia). Light-microscopical and ultrastructural studies indicated that it represents a new species of Leptomyxida. The partial 18S rDNA sequence of this amoeba is very similar to that of Leptomyxa reticulata.. These organisms, however, are very different in LM morphology and biology. Organisms assigned to the genus Rhizamoeba do not form a single clade in the 18S rDNA tree. This may indicate that the genus is an artificial grouping or that a number of studied strains were misidentified. The phylogeny and the systematics of leptomyxids require further investigation.
