    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 our remaining taxa are assigned (one of them questionably) to the genera Lanceomyonia, Stenorhynchia and Glossinulus of the families Hebetoechiidae, Trigonirhynchiidae, and Glossinotoechiidae, respectively.Peer reviewe

    The revision of Lower and Middle Devonian moroccan chonetacean brachiopods allows to recognize twenty species among which three are new : Ctenochonetes sougyi n. sp., Devonaria gevini n. sp., Loreleiella termierorum n. sp. Three others are provisionnally left in open nomenclature : Philippotia ssp., ? Holynetes sp., ? Dagnachonetes sp. All the remaining fourteen species were previously described from the Ibero-armoricain Domain, testifying to the paleo-biogeographical affinities of SW Europe and NW Africa during Lower and Middle Devonian times. The vertical range of the species brings some new stratigraphical data in the hercynian meseta and in the Anti-Atlas.La révision des brachiopodes Chonetacea du Dévonien inférieur et moyen du Maroc conduit à distinguer vingt espèces ; parmi celles-ci, trois sont nouvelles : Ctenochonetes sougyi n. sp., Devonaria gevini n. sp., Loreleiella termierorum n. sp. Trois formes sont maintenues en nomenclature ouverte : Philippotia ssp., ? Holynetes sp. et ? Dagnachonetes sp. Les quatorze autres espèces appartiennent toutes aux faunes du Domaine Ibéro-armoricain, attestant de l'homogéniéité paléobiogéographique du SW de l'Europe et du NW de l'Afrique au cours du Dévonien inférieur et moyen. La distribution verticale des espèces permet en outre d'apporter quelques précisions d'ordre stratigraphique dans le Meseta hercynienne aussi bien que dans l'Anti-Atlas.Racheboeuf Patrick R.
