Abstract

The discovery of Cantabroxanthus loredoensis n. gen., n. sp., from the Sponge Beds (middle Campanian) of Cantabria (Spain), increases the number of known Cretaceous brachyuran taxa that the coastline outcrops of Cantabria have yielded. The new genus is herein placed within the family Feldmanniidae (Etyoidea) on the basis of similarities with the genus Caloxanthus A. Milne-Edwards, 1864. Cantabroxanthus is also compared to the Palaeocorystoidea families, however important differences, for example, Cantabroxanthuspossesses an entire supraorbital margin, preclude any relationship with Palaeocorystoidea.

Keywords: Cantabroxanthus, Decapoda, Etyoidea, Feldmanniidae, Campanian, Cantabria.
