On the basis of long-term data (2007-2018), the fauna of robber flies (Asilidae) of the Republic of Mordovia was studied. Taking into account our own and literary data, 35 species of robber flies from 18 genera were noted. Of them, 19 species were noticed in the Republic of Mordovia for the first time. We presented the photos of morphological traits of Choerades fuliginosa (Panzer 1798), Choerades gilva (Linnaeus 1758), Choerades ignea (Meigen 1820), Laphria gibbosa (Linnaeus 1758), Andrenosoma albibarbe (Meigen 1820), Andrenosoma atra (Linnaeus 1758), Didysmachus picipes (Meigen 1820), Dysmachus stylifer (Loew 1854), Pamponerus germanicus (Linnaeus 1758), Philonicus albiceps (Meigen 1820), Machimus gonatistes (Zeller 1840), Neoitamus cothurnatus (Meigen 1820), Neoitamus cyanurus (Loew 1849), Dioctria atricapilla (Meigen 1804), Leptogaster cylindrica (De Geer 1776). Keywords: Asilidae, new records, robber flies, Russia INTRODUCTION Some of them (stenotopic species) occur only in one plant community type, others (eurytopic species) can inhabit two Diptera, along with Coleoptera, Hymenoptera, and or more types of plant communities (Dennis and Lavigne Hemiptera, is one of the largest orders in the world fauna. 1975; Londt 2006; Dennis et al. 2012; Astakhov 2013; The same applies to regional faunas. During the last Dennis 2018; Moreira and Maia 2018). decade, we studied the biological diversity of various insect Until now, the fauna of robber flies of the Mordovia groups of the Republic of Mordovia. This allowed us to remained poorly studied. And the species composition of identify many rare species and make species lists of some the robber flies of this territory is of considerable interest families (Ruchin and Kurmaeva 2010; Ruchin and Artaev for understanding the structure of the robber flies fauna of 2016; Semenov 2016; Ruchin and Egorov 2017a, 2017b, the entire Middle Volga region. There are some 2018a, 2018b, 2018c, 2018d; Ruchin and Makarkin 2017; publications covering the data on the robber flies of the Ruchin 2018; Ruchin and Grishutkin 2018; Ruchin and Mordovia. Redikortsev (1938) for the first time indicated Mikhailenko 2018; Ruchin et al. 2018, 2019a, 2019b; only one species of Laphria gibbosa for the fauna of the Tomaszewska et al. 2018; Ruchin and Antropov 2019). Mordovia State Nature Reserve. Plavilshchikov (1964) However, Diptera representatives are still underexplored noted 13 species of Asilidae family found in the Mordovia group. There is only some limited information about the State Nature Reserve (Leptogaster cylindrica, Dioctria Mordovian fauna of the Tipulidae and Limoniidae (Ruchin cothurnata, Lasiopogon cinctus, Laphria marginata, and Pilipenko 2015), Simuliidae (Budaeva and Ruchin Laphria gibbosa, Choerades gilva, Choerades fuliginosa, 2014), Bibionidae (Kornev et al. 2016), Syrphidae Andrenosoma atra, Asilus crabroniformis, Machimus (Chursina and Ruchin 2018b), Bombyliidae (Chursina and rusticus, Neoitamus cyanurus, Tolmerus atricapillus and Ruchin 2018a) and Tabanidae (Budaeva and Ruchin 2016). Echthistus rufineris). Antsiferova and Dobromyslov (1966) However, many groups are still unexplored. indicated two species - Leptogaster cylindrica and Robber flies (Diptera, Asilidae) are one of the largest Didysmachus picipes in the study of crops of Vicia - Avena families in the Diptera order. It contains more than 7,500 - Phacelia and Vicia - Avena mixtures in Mordovia. species (Dikow et al. 2017). The size of robber flies may Antsiferova (1979) noted two species Leptogaster vary from 5 to 60 mm (Dikow 2009). Robber flies are cylindrica and Asilus crabroniformis in the study of insect characterized by a different body shape (as a rule, with a communities of Medicago spp. Ruchin (2008) indicated cylindrically elongated abdomen) and a very diverse several Asilidae species: Dioctria oelandica, Didysmachus coloring of sclerites, which are often covered with thick picipes, Tolmerus atricapillus and Pamponerus germanicus hairs. Representatives of the family are known from in the Smolny National Park (Mordovia). Thus, 16 species various habitats. But the greatest species diversity is typical of robber flies were revealed in the Republic of Mordovia. for arid and semi-arid areas, as well as for tropical forests. During the current study, we found 13 species known Being active predators, adult flies and their larvae play a earlier for Mordovia. The species of Dioctria cothurnata, prominent role in ecosystems (Astakhov 2015). Robber Dioctria oelandica and Asilus crabroniformis have not flies can inhabit different types of terrestrial ecosystems. been found in the extensive material studied during our ASTAKHOV et al. – To robber flies fauna of Mordovia, Russia 995 study. And we don’t include them in the list presented Choerades fuliginosa (Panzer 1798) below. Thus, taking into account the new data, the fauna of (Figs 1-2) Literature.

European part of the former USSR, and stored in microtubes attached to the corresponding Western and Eastern Siberia, the Far East; most part of flies. For some rare species, we provided detailed Europe, Mongolia,? Japan; Nearctic (Canada, the USA) photographs of the morphological trait details, which can (Lehr 1988, 1991). also help in the future to identify these species. The photos Note. Lehr (1991) considered Choerades ignea as a were taken using the Canon EOS 1200D camera with a synonym of Choerades gilva, explaining this by the Canon macro f/4.5 100mm IS USM lens. To achieve similarity of the male genital structures of these species. sufficient focal depth, several individual images were But according to our opinion, external characters (coloring stitched together using the Helicon Focus 6 software. The of the hairs and macrosetae of the mystax and scutellum, subsequent processing of photographs was made in Gimp coloring of the abdomen tergites, etc.) are
