Biodiversity of cuckoo wasps and cleptids (Hymenoptera: Chrysididae: Cleptes, Elampus, Omalus, Pseudomalis, Philoctetes, Holopyga, Hedychrum, Hedychridium) of water protection zones of Kuma and podkumok rivers (North Casucasus)

Fauna, chorology and biological diversity of cuckoo wasps in the North Caucasus based on the analysis of the conducted studies for 1987-2017 have been studied. Ecological groups of the subfamily Hedychrinae, including 7 genera: Elampus, Omalus, Pseudomalus, Philoctetes, Holopyga, Hedychrum, Hedychridium and the genus Cleptes from the subfamily Cleptinae in the water protection zone of the Kuma and Podkumok rivers have been highlighted. The greatest species diversity of 22 selected localities is characteristic for clayey and clayey-sand slopes in the water protection zone of the Kuma and Podkumok rivers. Food specialization for a number of species from the genera Holopyga and Hedychrum in the feeding of pollen from plants: Apiaceae, Compositae and Euphorbiaceae has been revealed. An annotated list includes 35 species.
