New localities of species from the genus Laccobius Erichson, 1837 (Coleoptera, Hydrophilidae) in Poland. The paper presents new records from Poland of nine Laccobius species. Laccobius simulatrix present occurrence in Poland is confirmed. New localites of very rare in Poland species Laccobius albipes, L. alternus, L. gracilis and L. obscuratus are given

Beetles (Coleoptera) of wetlands and other aquatic habitats in the Polish part of the Polesie region found during the Balfour-Browne Club Meeting 2016

A total of 27 sites in the Polish part of the Polesie region were investigated for aquatic and wetland-associated beetles during the field sessions of the Balfour-Browne Club Meeting (23-30.05.2016). These comprised a mixture of fens and Sphagnum peat bogs, ditches draining fens, oxbow lakes of the Bug River, and sand excavations. A total of 408 species, belonging to all three sub-orders of beetle and 34 families were captured, including 351 species related to the aquatic environment (true water beetles – 157, phytophilous water beetles – 32, facultative water beetles – 1, false water beetles – 156, shore beetles – 157). Numerous rare, protected, species and those endangered in Poland or neighbouring countries were found. Information on three species (Agabus pseudoclypealis, Hygrotus polonicus and Berosus geminus) is important for our understanding of their geographical range limits. In the case of B. geminus, new data, in conjunction with information from Ukraine, points to the existence of an isolated island of occupancy in Polish and Ukrainian Polesie. Analysis of the material collected also reveals the high value of the study area, both nationally and internationally, for the protection of wetland beetle biodiversity

Portelmis guianensis sp. nov. from French Guiana (Coleoptera: Elmidae)

Portelmis guianensis sp. nov. is a new member of the Portelmis gurneyi-group. It was collected in Sinnamary, northern French Guiana. The species is externally similar to the other members of the genus, but males deviate considerably by the shape of the aedeagus. A detailed description and figures are given to facilitate easy identification of the new species. In addition, we have modified the key to species for males of the P. gurneyi-group given in Fernandes et al. (2010) by in-cluding the new species. The genus Portelmis Sanderson, 1935 now contains 5 members. Copyright © 2012 · Magnolia Press.Peer Reviewe

Materiały do poznania chrząszczy wodnych (Coleoptera: Adephaga, Hydrophiloidea, Byrrhoidea, Myxophaga) Puszczy Białowieskiej

151 species of water and shore beetles from 14 families are recorded from the Białowieża Primeval Forest. 31 of them are new for this region. Helophorus paraminutus Angus, 1986 is recorded from Poland for the first time

Materials to the knowledge of beetles (Coleoptera) of aquatic habitats in the Suwalski Landscape Park

The authors discuss the material collected in the Suwalski Landscape Park in the years 2009 and 2011-2013, almost exclusively obtained from standing waters. At 29 study sites, 1 204 individuals representing 109 species from 12 families were caught, of which 55 species have been recorded for the first time in the examined area. The most valuable were: Gyrinus distinctus, Haliplus fulvicollis, H. variegatus, Ilybius erichsoni, Graphoderus austriacus, Hydroporus glabriusculus, H. incognitus, Hydrochus ignicollis, H. megaphallus, Spercheus emarginatus, Anacaena globulus, Berosus frontifoveatus, Enochrus melanocephalus, Hydrophilus aterrimus, Cercyon quisquilius, C. unipunctatus, Limnebius aluta, Dryops anglicanus, Heterocerus fenestratus and Cyphon pubescens. The most species were found in small water bodies and lakes. The collected material was ecologically diversified; dominating groups were eurytopes as well as tyrphobionts and tyrphophiles, rheophilous species were also numerous. Taking into consideration data discussed in this paper and literature as well as the lack of complex studies, in waters of the Suwalski Landscape Park 139 beetle species have been recorded so far, of which 136 species represent true aquatic beetles (the authors provide the list of them). This number is similar or even higher than the one recorded in well studied, the most valuable and diversified habitats in protected areas of Poland. The Suwalski Landscape Park is also the place of occurrence of many species under protection, from the Red List of Animals in Poland or regarded as rarely occurring in Poland. It is also a refuge of many seriously threatened species in neighbouring countries. This confirms a great, overregional role of this area in the protection of aquatic beetles and their habitats
