New and revised occurrences of rhynchonelliformean brachiopods from the Languedocian (mid-late middle Cambrian) of the Iberian Chains are reported. The oldest assemblage corresponds to a level containing individuals of the new species Brahimorthis alvaroi and Nisusia sp. and is from the lower Languedocian Murero Formation. A younger assemblage is represented by Chilidorthis tecta from the Upper Languedocian Borobia and Torcas Formations. The geographic distribution and morphology of Brahimorthis, Chilidorthis and Bohemiella are reviewed and discussed. Moreover, evidence of the chilidium in Bohemiella and Chilidorthis and familial assignments of Brahimorthis, Saesorthis, Chilidorthis and Bohemiella are discussed. The new family Brahimorthidae fam. nov. is erected.
