An annotated checklist of species in the family Lagenophryidae (Ciliophora, Oligohymenophorea, Peritrichia), With a brief review of their taxonomy, morphology, and biogeography Author Mayén-Estrada, Rosaura Author Clamp, John C. text Zootaxa 2016 4132 4 451 492 journal article 10.11646/zootaxa.4132.4.1 ff19b27a-0f58-4285-b3b1-a7c9fa6a5ad2 1175-5326 257628 93EBA74C-E97B-42A6-9D82-1DF346533192 · Paralagenophrys Clamp, 1987 ( Fig. 5 ) has a lorica aperture that is similar to that of Lagenophrys , but its body and lorica aperture are twisted obliquely clockwise. The result is a lorica aperture that is displaced nearly 90o to the right and aligned almost parallel to the long axis of the body. The single species of Paralagenophrys is the only lagenophryid that is not restricted to a crustacean host. It also occurs on aquatic vascular plants and animals other than crustaceans (e.g., pulmonate snails) ( Clamp 1987b ).
