Etching limestones of Arnsbergian (Namurian A) age from the northern slope of the Cantabrian Mountains (N. Spain) has yielded a diverse ostracod fauna. One of the forms found is especially interesting as it represents a new genus ressembling in some aspects the family Rectonariidae. The new genus Gruendelella is described.
