Abstract
Abstract. A new fossil species of the silvanid flat bark beetle genus
Cathartosilvanus Grouvelle is described and illustrated from Baltic amber. Cathartosilvanus siteiterralevis sp. nov. differs
from recent and fossil congeners in the distinct, sharp denticle found along
its posterior pronotal angle. The phenomenon of specific body parts becoming
disconnected, and the compression of specimens is briefly discussed and
interpreted in the context of amber taphonomy. The specimen under study
appears to be an uncommon case of a weakly sclerotized beetle imago becoming
entrapped in resin shortly after moulting.

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.
