The presence of Haliplus ruficollis (De Geer, 1774) (Haliplidae), Hydroglyphus hamulatus (Gyllenhal, 1813) (Dytiscidae), Cercyon marinus (Thomson, 1853), Hydrophilus dauricus Mannerheim, 1852, Paracymus aeneus (Germar, 1824) (Hydrophilidae), and Ochthebius evanescens Sahlberg, 1875 (Hydraenidae) in Mongolia is confirmed by new findings. For 76 species, new faunistic records are listed.
