N2 - Amoebae of the genus Leptomyxa have variable morphologies and can only be reliably identified using molecular data. However, species distinction based on the 18S rRNA gene sequence is difficult due to the very low level of sequence divergence among morphologically different species. The database for other genes is much smaller, and genomic data on Leptomyxa is almost absent. In this study, we describe two new terrestrial species of the genus Leptomyxa isolated from Northwestern Russia, Leptomyxa botanica n. sp. and Leptomyxa monrepos n. sp. Both species easily adopt an expanded fan-shaped form and have a complex structure of the nucleolar material. Phylogenetic analyses show a derived status of these two species. They form a clade with Leptomyxa valladaresi. Our tree confirms that the 18S rRNA gene sequences of Leptomyxa species are split into two large clades. The morphological synapomorphies of these clades are not obvious. This analysis is complicated by the lack of reliable morphological data on many sequenced strains and probable misidentification of some isolates.
