M. lindbergorum (BRUCE) was found in Pieniny Mts., in southern Poland. The species is new to the Polish fauna
This paper contains information on 3 members of the family Byturidae: Byturus ochraceus, B. tomentosus, and Xerasia meschniggi. On the basis of collected material and literature data maps of distribution these beetle species were prepared. Moreover, the paper is supplemented with a key for the identification of the insects under discussion and a taxonomic review of European Byturidae.
Saproxylic beetles are essential for the proper functioning of forest ecosystems. However, intensive forest management has led to the disappearance of suitable microhabitats of many species associated with dead wood. Cucujus cinnaberinus is an endangered saproxylic beetle which develops under the bark of dead wood. The species usually occurs in protected areas, however, some populations inhabit long-term managed forests in Central Europe. In this study, we analyzed the effect of nine silviculture-related and decay-related factors on the C. cinnaberinus microhabitat selection in managed forests. We found that potential sun exposure, bark thickness, dead wood moisture and the hardness of dead wood have a significant effect on the C. cinnaberinus microhabitat selection. The species prefers sun-exposed dead wood with thicker bark at an intermediate stage of decay with undecomposed xylem, but avoids completely dry pieces. Furthermore, we found no confirmation of a direct connection between dead wood diameter and the occurrence of C. cinnaberinus. We stressed that logging residues or stumps are mostly unsuitable for C. cinnaberinus development.
The paper presents new localities of 4 species of Trogidae in Poland. The information in the paper was completed with historical material from the Institute of Systematics and Evolution of Animals in Cracow and comes from the private entomological collections. The species was collected from 14 regions.
The paper presents unpublished information on the occurrence of rare and endangered beetles (Coleoptera) in the Niepołomice Forest near Kraków in 1993–2017. Faunistic data on the occurrence of 28 species of beetles, representing the families of Carabidae, Cleridae, Monotomidae, Coccinellidae, Elateridae, Eucnemidae, Lampyridae, Melandryidae, Mycetophagidae, Ptinidae, Scarabaeidae, Staphylinidae, Throscidae, Trogossitidae, and Zopheridae, are presented together with short descriptions of identified species.
