[Ultrastructural characteristics of the cortex and of the membranelles of the ciliate Espejoia mucicola (Oligohymenophora, Hymenostomata, Tetrahymenina)].
It was shown in a detailed study of the cortex and buccal organelles of Espejoia that, at the ultrastructural level, the general plan of organization of this ciliate conforms to that of Tetrahymenina. Specific variations seen in the cortex and membranelles bring out the very pronounced affinities of Espejoia to the genus Glaucoma and other related ciliates. In view of the foregoing and on the basis of reccent findings on morphogenesis, we confirm the taxonomic position of Espejoia mucicola among Tetrahymenina in the family Glaucomidae.
