The paper presents data on a new record of a very rare insect, Leptura aurulenta (Coleoptera, Cerambycidae), in the Mordovia State Nature Reserve (Russia). This is a third reliable registration of this species within Russia. It expands the range of this beetle to 600 km to the east. We have presented an original biotope description, data on distribution and biology of L. aurulenta.Key words: Coleoptera, Leptura aurulenta, Mordovia State Nature Reserve, new record
IntroductionThe Mordovia State Nature Reserve is located in the Temnikov district of the Republic of Mordovia. It belongs to the Central Russian subprovince of the Eastern European province of the European broad-leaved forest region on the wooded rightbank of the River Moksha (Gribova et al., 1980). The forest-steppe naturally marks the boundary of the protected area from the south. The climate of the Mordovia Reserve is related to the Atlanticcontinental region of the temperate zone (Gafferberg, 2015). Intensive entomological studies of recent years have shown many new and interesting findings of Coleoptera species in the Mordovia Reserve area (Legalov et al., 2014;Egorov et al., 2015Egorov et al., , 2016Egorov & Shapovalov, 2017;Semenov, 2017).The family of longicorn beetles (Cerambycidae) belongs to one of the most interesting taxonomic groups of Coleoptera. In ecosystems, the species of this family participate, first of all, in the wood biodegradation (at larval stage) and pollination of flowering plants (imago). The longicorn beetles' research is also important for biodiversity study. However, some species of longicorns are very rare and listed in the Red Data Books on federal and regional level. The present report contains information about the discovery of the rarest longicorn beetle in Russia -Leptura aurulenta Fabricius, 1793 in the Mordovia State Nature Reserve.
MaterialThe Republic of Mordovia, Temnikov district, 17 km NW from the city of Temnikov, Mordovia State Nature Reserve, forest square 324, 15.07.2017, 1 specimen, A.B. Ruchin (Fig. 1). The specimen was transferred to the collection of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia).
Description of the biotopeThe female L. aurulenta was caught on the western narrow clearing of forest square 324 of the Mordovia State Nature Reserve. The beetle sat on the inflorescence of a plant of the Apiaceae family. This quarter has a developed forest and meadow vegetation. In the south-western and north-western corners of this quarter there are small areas of ripening and ripe lime trees, in the stand of which occur sparsely Quercus robur L.,
