New Late Cretaceous records of Cenomanocarcinus (Decapoda, Brachyura, Palaeocorystoidea) from Austria and Germany

New records of Late Cretaceous cenomanocarcinid crabs are presented. A single, isolated carapace from the middle Santonian of Austria exhibits several distinct features, including a smooth posterolateral margin, and absence of two conical inflations in the intestinal region on both sides of the axial ridge that do not reach the posterior margin. Based on these unique characters, it can be differentiated from all other congeners and described as a new species, Cenomanocarcinus lenzenwegeri. This record is considered to be the youngest European occurrence of the genus known to date. Cenomanocarcinus sp. is recorded from the lower Turonian of Germany, on the basis of a single individual preserved in ventral aspect, previously identified as a tentative representative of the Carcineretidae. The new European occurrences presented herein document the persistence of the genus in that part of the world at least into the Santonian.
