Fauna of Неteroptera (Insecta: Hemiptera) in the Republic of Mordovia (Russia)

The suborder Heteroptera (order Hemiptera) is one of the most interesting groups of Rynchota. It is found in various ecosystems around the world and belongs to predators, parasitous (in particular hematophagous), mycetophagous and herbivorous types. Species with mixed nutrition are common. The study is aimed to describe the fauna and distribution of hemipteran insect species in the Republic of Mordovia (the central part of the European part of Russia). The study was conducted from 2004 to 2022. Specimens were collected using traditional hemipteran insect collecting methods (manual collecting, light trap, entomological net, Malaise trap, Merike plates, window and soil traps). We examined 4895 specimens of Hemiptera. Species diversity of Heteroptera (order Hemiptera) of Republic of Mordovia accounts for 363 species from 34 families. Of these, 15 species ( Campylosteira verna, Allorhinocoris flavus, Grypocoris sexguttatus, Acetropis gimmerthalii, Geocoris grylloides, Platyplax salviae, Emblethis ciliatus, Aellopus atratus, Rhyparochromus quadratus, Parapiesma quadratum, Berytinus montivagus, Pyrrhocoris marginatus, Enoplops scapha, Dybowskyia reticulata, Ventocoris halophilus ) are listed for the region for the first time. Twenty-three species ( Agramma femorale, Adomerus biguttatus, Aelia acuminata, Carpocoris fuscispinus, Coreus marginatus, Dolycoris baccarum, Eurydema oleracea, Gerris lacustris, Graphosoma lineatum, Kleidocerys resedae, Labops sahlbergii, Lopus decolor, Lygus pratensis, Nithecus jacobaeae, Palomena prasina, Polymerus unifasciatus, Prostemma aeneicolle, Pyrrhocoris apterus, Rhyparochromus pini, Stenodema calcarata, Cymus glandicolor, Eremocoris plebejus, Aphanus rolandri ) constitute the main population of the Heteroptera fauna given in the dataset. The species diversity of Heteroptera of the Republic of Mordovia is roughly similar in number of species to that of neighbouring regions.
