On commission of the state Rhineland-Palatinate (Germany) in 2011 a monitoring for four beetle species listed by the European Commission as FFH-species of European interest was carried out. Methods on monitoring and results are presented and discussed.
Graphoderus bilineatus (Dytiscidae) was searched along the upper Rhine close to Neuburg during t...
The genus Ochthebius LEACH, 1835 contains 365 palearctic species, but many species are still awaiting description. Although Europe is considered to be reasonably well explored with respect to this genus, the first author collected a new species during a field trip in October 2015. Ochthebius (s.str.) scopuli (Coleoptera: Hydraenidae), a member of t...
In recent years, large‐scale DNA barcoding campaigns have generated an enormous amount of COI barcodes, which are usually stored in NCBI 's GenBank and the official Barcode of Life database ( BOLD ). BOLD data are generally associated with more detailed and better curated meta‐data, because a great proportion is based on expert‐verified and voucher...
Saproxylic beetles (Coleoptera) are important for biomonitoring to evaluate the state of ecological conservation of forest ecosystems. However, beetle larvae are rarely considered due to their difficult identification.
Here, we evaluate the use of beetle larvae, alongside adult specimens, for monitoring. Forty sifting samples from deadwood structur...
Forest affinity of the beetle species of Germany (Coleoptera)
All 6732 species of Coleoptera established in Germany (of which 30 occur in two subspe-cies and 5 occur in three subspecies) are assigned to one of eight different categories based on their preference for forest habitats. 58.6 % (3965 taxa) of the taxa live in forests. 30.8 % (2087) of b...
The first record of the primeval forest relict species Farsus dubius (Piller & Mitterpacher, 1872) in Germany near Neuhofen (Anterior Palatinate) on the 11th July 2023 in a light trap is presented and discussed.
Studies on the diverse rheophilic and riparian beetle fauna (Coleoptera) of the Nahe river between Boos and Hoppstädten-Weiersbach (Rhineland-Palatinate):
Despite intensive research on the beetle fauna of the Nahe valley, very little is known about the fauna of the river and its banks. A total of 12,632 beetles in 364 species were recorded in eleve...
Trichoferus pallidus (Olivier, 1790) colonizes old relict oak sites and is one of the rarest longhorn beetles in Germany. Here, the first discovery of the species for the Rhine Province at the Roßstein in the Middle Rhine Valley (Rhineland-Palati-nate) is presented. Two specimens were recorded between 10 p.m. and midnight CET on the 31th July 2020...
The first record of Contacyphon punctipennis (Sharp, 1872) for Rhineland-Palatinate in the "Bragphenn" near Ormont on the 24 th October 2022 is discussed. The accompanying beetle fauna as well as records from the spring-driven bog "Dreiherrige Stein" near Hersdorf-Weißenseifen are presented. The records show the importance of even small montane bog...
Helophorus cincticollis Guillebeau, 1893 is confirmed as a European species as a result of recent discoveries in the spanish province of Cadiz.
Here we present new records of the rare weevil Bagous diglyptus (Curculionidae). The species is rediscovered in the German federal state North Rhine-Westphalia after almost 85 years, while two new record in Rhineland-Palatinate are the first ones after roughly 50 years. The collecting method and the circumstances of the records are discussed. It is...
On three different managed types (fallow, mowing by hand, mowing by crawler tractor) of wet meadows (Schoenetum nigricantis-Association) close to Konstanz, along the shore of Lake Constance, Southwest-Germany, ground dwelling beetles were collected by pitfall traps between 22 nd of March and 17 th of May 2016. Within four collecting periods of two...
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 sp...
Während Exkursionen in das Neuwieder Becken konnten einige für das Rheinland bemerkenswerte Käferfunde verzeichnet werden. Die Erstfunde von Ptilium modestum (Ptiliidae) und Thoracophorus corticinus (Staphylinidae) für das südliche Rheinland sowie von Ampedus elegantulus (Elateridae) für die Rheinpro-vinz werden vorgestellt. Darüber hinaus werden d...
The water-scavenger beetle Laccobius ytenensis, the rove beetle Lesteva sicula heeri, the rare camphor beetle Stenus kiesenwetteri, and the reed beetle Plateumaris discolor have been recorded in wetlands in the Burgwald for the first time in the German federal state Hesse. The records will be discussed and further findings are presented in a specie...
Käfer nässegeprägter Lebensräume bilden bei uns artenreiche Lebensgemeinschaften. In Bayern sind insgesamt 1.470 Arten aus den verschiedenen Feuchtbiotopstypen bekannt, darunter 72 Moorkäferarten. Vom 12. bis 16. Mai 2016 wurden 17 Standorte im Nationalpark Bayerischer Wald hinsichtlich ihrer aquatischen Käferfauna untersucht. Es wurden 2.504 Käfer...
As a data store of biodiversity, scientific collections should be well-maintained and digitalized according to the latest taxonomic status. The usability and research possibilities of a collection increases enormously with its digitalization. The Zoological Research Museum Alexander Koenig (Bonn) is home to the Rhineland collection, which contains...
Two recent records of the diving beetle Hydroporus longicornis Sharp, 1871 in the Rhine Province are presented. Additionally, old records of its sister species Hydroporus melanarius Sturm, 1835 were revised with the results that another nine specimen of Hydroporus longicornis were misidenti-fied. A distribution map showing all known records of the...
The first records of Cercyon castaneipennis, Enochrus fuscipennis and Enochrus nigritus (Hydrophilidae) in the Rhineland are presented. Furthermore, rerecords and old records of Bidessus delicatulus, Hydrovatus cuspidatus, Laccornis oblongus (Dytiscidae), Oulimnius rivularis, Limnius muelleri (Elmidae) and Bagous lutosus (Curculionidae) are discuss...

By the example of 21 aquatic beetle species, which occurred in a former fen near Bornheim (Rhineland / Germany), the change of the fauna in the northern Rhineland is examined. Based on a literature and a collection evaluation (1,024 records) the spatial and temporal distribution of the species is determined and represented in distribution maps. Thr...
