Two new species of the genus Psyllaphorura Bagnall, 1948, namely P. silvestris sp. nov. and P. pseudopodis sp. nov., are described from the European Russia. The former species can be compared to the Nearctic P. obesa (Mills, 1934) which has almost the same number of dorsal pseudocelli, but differs in having compound vesicles in PAO. Psyllaphorura pseudopodis sp. nov. is similar to P. altaica Weiner, Stebaeva & Kaprus’, 2019 recently described from the Altai Mountains, southern Siberia. Both these species have the same number and arrangement of the cephalic pseudocelli. Nonetheless, P. pseudopodis sp. nov. can be distinguished by the absence of pseudocelli on Abd. IV, only 2+2 dental setae and a shorter unguiculus. Besides this, P. pseudopodis sp. nov. is unique in the presence of a pair of ventral swellings on the fourth abdominal segment. Based on a revision of the types, P. sensillifera (Martynova, 1981) is considered a senior synonym of P. raoheensis Sun & Wu, 2013. Taxonomic notes on the most important diagnostic characters of the genus are given, as well as a key and a table summarizing these characters in all Psyllaphorura species known in the World so far.

A variety of baits in simple traps can be very helpful in the study of insect biodiversity. The study was conducted on the possibility of using crown traps with vinegar and beer during their joint expo- sure. Representatives of 10 insect orders were captured. Vinegar baits are less effective than beer baits. There were more insect speies and individuals in the beer traps. Representatives of the orders Coleoptera, Lepidoptera, Diptera and Hymenoptera were the most numerous in all traps. The only family Formicidae was well lured by vinegar. There were more than 87 species from 31 families in the species diversity of Coleoptera. There were 52 species in wine vinegar traps and 64 species in beer traps. It is better to use traps with vinegar bait in conjunction with beer baits.
