International audience. The description and study of rhynchonellid brachiopods recently collected from the Lower Devonian of the Ougarta area in western Algerian Sahara permitted the revision of previously described and/or listed taxa, mainly from Morocco. Palaeobiogeographically, the nine identified taxa share many similarities with the rhynchonellid fauna of the Ibarmaghian Domain. Five of the nine identified taxa belong to three genera of the Family Nucinulidae Sartenaer, 2004. Three of these are new taxa, namely Nucinulus orbignyanus crassicostus subsp. nov., Cuninulus ougartaensis sp. nov. and Palinulus saharaensis sp. nov. The four remaining taxa are assigned (one of them questionably) to the genera Lanceomyonia, Stenorhynchia and Glossinulus of the families Hebetoechiidae, Trigonirhynchiidae, and Glossinotoechiidae, respectively.
