Mayén-Estrada, Rosaura & Clamp, John C., 2016, An annotated checklist of species in the family Lagenophryidae (Ciliophora, Oligohymenophorea, Peritrichia), With a brief review of their taxonomy, morphology, and biogeography, Zootaxa 4132 (4), pp. 451-492 : 456

· The diagnosis of Setonophrys Jankowski (1986)

was emended by Clamp (1991) to include all lagenophryid species that have a lorica aperture with a rigid anterior lip and a flexible posterior lip that is pulled completely inside the lorica to press it against the anterior lip and close the aperture ( Fig. 5 ).
