Four new species of Stenoscismatacea, Camerisma (Callaiapsida) alcaldei, C. (Callaiapsida) paucicostata, Cyrolexis granti, and Stenoscisma winkleri are described from the Cantabrian Mountains. The two species of Callaiapsida, from the lower and upper Bashkirian, are the oldest attributed to the subgenus, and they show transitional characters between C. (Camerisma) and typical C. (Callaiapsida); moreover, the distribution of the subgenus is now extended from the Arctic. Cyrolexis granti from the Kashirian is also the oldest species of the genus, previously known only from the Permian.
