N2 - The Macaronesian species of the muscid genus Limnophora are reviewed with special emphasis on the fauna of the western Canary Islands. The genus is represented by 14 species in the Macaronesian archipelagos, with 10 species in the Canary Islands, 4 species in the Cape Verde Islands, and 3 species in Madeira. Limnophora obsignatula sp. nov. is endemic to the western Canary Islands, where it replaces the widespread continental L. obsignata (Rondani). It is further shown that L. paneliusi Emden, a species so far considered endemic to the Cape Verde Islands, is widespread in the Canary Islands. Two species, L. obsignata (Rondani) and L. tigrina Am Stein, are removed from the list of Canarian Muscidae as based on misidentifications of other species with a mesonotal ?Anthomyia-pattern?. Limnophora (Calliophrys) riparia capoverdica Emden, a taxon described from the Cape Verde Islands, is synonymized with L. riparia (Fallen), syn. nov. Distribution data and illustrated diagnoses are given for each species. The species account is finalized with an identification key to males and females. An assessment of the ovipositor as a characters source in phylogeny and species recognition is made for 12 species of Limnophora. Finally, it is pointed out that several species are acutely threatened due to habitat disturbance.
