Based on literature analysis and museum collections, the range of Mimela holosericea (Fabricius, 1787) is defined. Outside of Russia, M. holosericea is distributed in Kazakhstan, Mongolia, some northern provinces of China, the Korean peninsula and Japan. Within the Russian Federation, the species is recorded in 30 administrative regions (the Far East, Eastern, Western and Southern Siberia, the Urals, Volga River basin and Central Russia). It is most abundant and most frequently recorded at the Far East: the Jewish Autonomous Region, Primorsky Krai, Khabarovsky Krai, Amur and Sakhalin Regions. In the western part of its range - Volga River basin and Central Russia - the species is sporadically distributed, though the number of specimen records here has increased in recent years. The main habitats are sparse pine forests (on glades, roadsides, fringes) and floodplain cenoses.

The paper presents data on a record of Allonyx quadrimaculatus (Schaller) in the Republic of Mordovia (Russia, Central European Territory) and also the whole known information about specimens of the species stored in Russian museums. We discuss the species’ distribution which is considered as intermittent. Data on biology of Allonyx quadrimaculatus and description of its newly found habitat are presented.
