In Westphalian strata of the Cantabrian Mountains, northern Palencia, Spain, the sphinctozoan sponges Amblysiphonella and Cystauletes are quite common; Sollasia is much rarer. This is the first occurrence of Cystauletes in Europe. The great variability of Amblysiphonella barroisi and Cystauletes mammilosus is demonstrated with abundant material. One new species Cystauletes maior is described. All three genera are associated with Dasycladaceae, which indicates a very shallow water environment.
