Abstract This paper reports on a new species of the Baikal endemic sponge (fam. Lubomirskiidae) Swartschewskia khanaevi sp. nov. The description of this species is based on morphological and molecular data (ITS and mitochondrial IGRs). Morphologically, S. khanaevi sp. nov. differs from S. papyracea by loose tracts arranged in

Moreover, specimens of S. khanaevi sp. nov. show a peculiar structure of the aquiferous system at the body surface that may be an adaptive trait for environmental conditions. Phylogenetic analysis has revealed that S. khanaevi sp. nov. forms a well-supported (0.99) monophyletic clade with S. papyracea and is allocated as its sister taxa.
