At the end of 2019 an old collection of insects was found in the Zoological Museum of Saratov State University. It was collected in the vicinity of Saratov, in the Lower Volga region, as well as in the North Caucasus and Transcaucasia, by young Andrey A. Richter while he was studying at school and Saratov University (1926–1930). The collection (185 specimens) was not processed, with most insects left unidentified. Nevertheless, it has been well preserved. Its examination has already produced first results important for better understanding of A. A. Richter biography.
