Abstract
Abstract. Acritus sutirca sp. nov. is described and illustrated from Eocene Baltic amber on
the basis of one adult male specimen. As the first extinct member of the
subfamily Abraeinae (Histeridae) and the smallest known fossil histerid
specimen, this material was examined using a combination of light microscopy
and X-ray micro-computed tomography (µCT). Internal features of the
abdomen are well preserved, allowing us to study sclerotized parts of the
aedeagus and illustrate these structures in detail. The current finding
expands the range of known Histeridae diversity from the Eocene (48–34 Ma)
“amber forests” of Europe. The absolute size limits and the probable
average size for Baltic amber coleopteran inclusions are also briefly
discussed (urn:lsid:zoobank.org:pub:A2B17479-8628-47C7-A8D4-3E0789BF088B).
期刊介绍：
Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
