A new fossil species of <i>Attagenus</i> Latreille (Coleoptera: Dermestidae) in Rovno and Baltic ambers, with a brief review of known fossil beetles from the Rovno amber Lagerstätte

Abstract

Based on two specimens originating from Eocene Rovno and Baltic ambers, Attagenus (Aethriostoma) gedanicissimus sp. nov. is described, illustrated and compared with the related fossil Mesozoic species A. (Aethriostoma) turonianensis Peris et Háva, 2016. The common beetle species for Baltic and Rovno ambers suggests the exceptional temporal and geographical closeness of palaeoecosystems that produced both amber deposits. An updated checklist of Coleoptera known from Rovno amber (57 species belonging to 20 families) is compiled and provided with a bibliography of the original descriptions. The registered Rovno amber beetle assemblage contains only eight species that also occur in Baltic amber (14 %), while the similarity at the generic level is 56 % at the moment. The relationship between the Rovno and Baltic amber deposits and subjectiveness of present-day results of the beetle assemblage research are briefly discussed (urn:lsid:zoobank.org:pub:289B5A43-C57A-4B75-8A15-6E61F4AFCD81).
