A new monotypic genus and species of brachyurans, Petersbuchia thauckei n. gen. n. sp., is described from southern Germany. The holotype, an incompletely preserved carapace, was collected from a thick-bedded spongiolithic limestone of the Upper Jurassic Treuchtlingen Formation (early late Kimmeridgian, Acanthicum Zone). Petersbuchia adds to the diversification hotspot of early true crabs within the sponge-microbial magnafacies along the northern shelve of the Tethys Ocean in general and to the brachyuran fauna of the Treuchtlingen Formation in special.
