We report the first finding of Bathynellacea, discovered in Mongolia. We also report a new species of the genus Altainella Camacho, 2020, which was previously recorded only in the western edge of Russia.Altainella mongoliensis sp. nov. was found in the interstitial hyporheic region of the Onon River Basin, Mongolia, by inserting a core approximately 1.2 m deep and extracting the underground interstitial water. The new species exhibited sexual dimorphism in thoracopod VII, uniquely observed within the genus Altainella. We provide a morphological description and remarks on the new species with molecular information based on the 18S rDNA and partial CO1 gene sequences. We emphasise the need for continued research on the subterranean biodiversity in previously neglected regions by reporting the first discovery of macro-stygobionts in Mongolia.Taxonomic Coverages
