A fossil beetle from the Upper Buntsandstein (Röt-Folge, Lower Triassic) in Karlsruhe Durlach-Eisenhafengrund is described. The specimen is one of the oldest known beetle findings in Germany. According to its stratigrafic context, the finding layer can be correlated with the Voltzia-Sandstone (E-France), which also yielded fossil beetles. The silty matrix, in which the beetle occurs, is interpreted as seasonal playa sediment. The beetle was fragmented during extraction. The lack of diagnostic features of elytra, scutellum and pronotum does not allow to assign the specimen to a family. However, the elytral humeral callus, the set off pronotum with caudolaterally concave margins combined with the size of almost 15 mm allows a diagnostic distinction from other coeval Coleoptera at least in Europe. Therefore, it is justified to refer the specimen from Durlach-Eisenhafengrund to a new genus and species: Durlachia striata.
