Abstract This study focuses on the fossil beetles assigned previously to the family Hydrophilidae described from the localities in the southern part of the Upper Rhine Graben: Brunstatt (France, Alsace) and Kleinkems (Germany, Baden-Württemberg) (both dated ca. to Eocene-Oligocene boundary, 34 Ma). The identity of Escheria convexa Förster, 1891 is fixed by the designation of its neotype, the species is redescribed, illustrated, transferred from the hydrophilid genus Hydrobius Leach, 1815 to the… 

Figures and Tables from this paper

Modern hydrophilid clades present and widespread in the Late Jurassic and Early Cretaceous (Coleoptera: Hydrophiloidea: Hydrophilidae).

The presence of extant clades (Hydrophilinae: Hydrobiusini, Acidocerinae) in the Early Cretaceous and the wide distribution of the Hydrobioidesini in both Gondwana and Laurasia at the same time suggests that the principal extantClades of thehydrophilidae are at least of Early–Middle Jurassic origin.

An Aquatic Water Scavenger Beetle in Early Miocene Amber from the Dominican Republic (Coleoptera: Hydrophilidae)

The fossil demonstrates that representatives of the family Hydrophilid beetle may already have been widespread and common by the Early Miocene, and indicates a possible Miocene/post-Miocene extinction of the aquatic insect fauna on the island of Hispaniola.

Fossil ants (Hymenoptera: Formicidae): ancient diversity and the rise of modern lineages

The ant fossil record is summarized with special re ference to the earliest ants, first occurrences of modern lineages, and the utility of paleontological data in reconstructi ng evolutionary

Insect Fauna of the Late Miocene Locality of Öhningen (Germany) Less Diverse Than Reported: An Example of the Hydrophilid Beetles (Coleoptera)

The diversity of the hydrophilid beetles in Öhningen is thus lower than previously reported, but still being slightly higher compared to other European Paleogene and Neogene localities.



The unusual occurrence of aquatic beetles in amber, copelatus aphroditae balke, n. sp. and C. predaveterus miller, n. sp., (Coleoptera: Dytiscidae: Copelatinae)

Two new species are described based on a single female from Baltic amber (Eocene), and C. predaveterus Miller, new species, is described from five specimens preserved in Dominican amber (late earlyMiocene to mid-Oligocene).

Fossil water scavenger beetles of the subtribe Hydrobiusina ( Coleoptera : Hydrophilidae ) from the Late Oligocene locality of Aix-en-Provence ( France )

Two species assigned to the subtribe Hydrobiusina from the Late Oligocene locality of Aixen-Provence (France) are examined andHydrobius obsoletus Heer, 1856 is removed from the Hydrophiloidea and placed in Coleoptera incertae sedis based on the examination of its holotype.

A check list of Copelatus Erichson 1832 species (Coleoptera Dytiscidae) from Afrotropical and Madagascan regions with a review of published penis drawings

The taxonomical history of African Copelatus is reviewed and the geographical variation in species richness is discussed.

This catalogue treats the beetle superfamily Hydrophiloidea, commonly referred to as one of the major groups of aquatic beetles, as a relatively strict sense, comprising the families Helephoridae, Epimetopidae, Georissidae, and other CABI sites.
