An update on the water beetle fauna of Mongolia (Coleoptera: Haliplidae, Dytiscidae, Helophoridae, Hydrophilidae, Hydraenidae, Dryopidae) with new and additional country records

Abstract

New faunistic data are presented for six water beetle families from Mongolia. The family Dryopidae, with the genus Dryops Olivier, 1791, and the genus Platambus Thomson, 1859 of the family Dytiscidae are recorded for the first time from Mongolia. Agabus semipunctatus (Kirby, 1837), previously known only from the Nearctic Region, is reported for the first time from the Palearctic. Eight species of water beetles are recorded for the first time from Mongolia: Dytiscidae (6): Agabus mandsuricus (Guignot, 1956), A. semipunctatus, Platambus maculatus (Linnaeus, 1758), Hydroporus cf. breviusculus Poppius, 1905, H. goldschmidti Gschwendtner, 1923, H. striola (Gyllenhal, 1826); Hydrophilidae (1): Laccobius binotatus Orchymont, 1934; Dryopidae (1): Dryops similaris Bollow, 1936. The presence of Rhantus suturalis (Macleay, 1825) is confirmed for the fauna of Mongolia. First province records are listed for 41 species, and for four species of Hydraenidae, the list of literature-based province records provided by Prokin et al. (2020) is supplemented or respectively corrected.
