Trogossitidae, Lophocateridae, Peltidae and Thymalidae (Coleoptera: Cleroidea) of Poland: distribution, biology and conservation

Abstract Distributional data for 10 species of Peltidae, Lophocateridae, Trogossitidae and Thymalidae recorded from Poland are summarised, and numerous unpublished records are reported. Data on feeding and habitat preferences are analysed. Calitys scabra and Temnoscheila caerulea are probably extinct in Poland. Grynocharis oblonga, Nemozoma elongatum and Tenebroides mauritanicus are relatively common in Poland. Nemozoma caucasicum is currently spreading within Europe and several new records in Poland are reported. Peltis ferruginea, P. grossa, and Thymalus limbatus are restricted to natural forests in Poland, where they are sometimes abundant. We suggest adding Peltis ferruginea and Thymalus limbatus to the Polish Red List of Animals. The opinion that Grynocharis oblonga and Tenebroides mauritanicus are relicts of natural forests does not seem justified.
