Natalia MUNTEANU MOLOTIEVSKIY, Svetlana BACAL, Oxana MUNJIU, Anna MOLDOVAN Dytiscidae is the largest family of aquatic beetles, with almost 4000 species and 160 genera included in 10 subfamilies. Larvae and adults of almost all species are aquatic; they live in a wide variety of freshwater habitats: stagnant water, running water and groundwater (Larson et ah, 2000; Nilsson, 2001). For European fauna six subfamilies are known: Agabinae, Colymbetinae, Copelatinae, Dytiscinae, Hydroporinae and Laccophilinae. In the Republic of Moldova following subfamilies and genera occur: Agabinae (.Agabus, Ily bins and Platambus), Colymbetinae (■Colymbetes and Rhantus), Copelatinae (Copelatus), Dytiscinae (Acilius, Grap ho derűs, Су bister, Dytiscus and Hydaticus), Hydroporinae (Graptodytes, Hydroglyphus, Hygrotus, Hyp hydrus) and Laccophilinae (.Laccophilus). Around 2835 species in 169 genera and 4 subfamilies were described for Hydrophilidae from all continents. Altogether, about 70% of Hydrophilidae are aquatic, adults and larvae of most species live in stagnant water (Hansen, 1991, 1999; Short, Hebauer, 2005). In Europe Hydrophilidae are represented by 29 genera from 4 subfamilies. In the Republic of Moldova 14 genera from one subfamily are known so far. The first faunistic data on aquatic beetles from the Republic of Moldova has been recorded by Miller and Zubovskii (1917), later on completed by Ruscinsky (1933-1934); additional information on some aquatic beetle species has been presented by Medvedev and Shapiro (1957), Yaroshenko (1957), Bacal, Munteanu, Toderas (2013) and Molotievskiy, Bacal (2015). Ecological data regarding aquatic beetles were presented by Ostafichuk (1983) and Neculiseanu et al. (2003, 2007). Material and methods The following list of aquatic beetles is based on a combination of literature records, examination of museum specimen collection of the Institute of Zoology, Academy of Sciences of Moldova and sampled material during 2013-2014 years from different aquatic basins from the Republic of Moldova. Insects were collected using light traps and a drag-type net. The nomenclature of the beetle species is based primarily on the works of Kryzhanovskij (1965), Lobi and Smetana (2004) and Bouchard et al. (2011). Results and discussions The fauna of the aquatic beetles of the Republic of Moldova is represented by 59 species, 35 genera, 9 subfamilies and 5 families: Gyrinidae (2 species from 2 genera), Haliplidae (2 species, 2 genera), Noteridae (2 species, 1 genus), Dytiscidae (29 species, 16 genera) and Hydrophilidae (24 species, 14 genera).
