Six species of aquatic Coleoptera are recorded from the Lipetsk Oblast for the first time: Haliplus flavicollis Sturm, 1834 (Haliplidae); Agabus paludosus (Fabricius, 1801), Ilybius neglectus (Erichson, 1837), I. wasastjernae (C.R. Sahlberg, 1824), Hydroporus incognitus Sharp, 1869, Hygrotus versicolor (Schaller, 1783) (Dytiscidae), Hydrobius rottenbergii Gerhardt, 1872 (Hydrophilidae). Two species (Ilybius wasastjernae, Hydroporus incognitus), are recorded at the southernmost limits of the known range in the European part of Russia. The record of Contacyphon laevipennis (Tournier, 1868) is confirmed by provided material. For three species, original photographs of the habitus and male genitalia are provided, and for two ones – of the habitat.
