Lagenophrys Stein, 1852

Diagnosis. Solitary, loricate, with lorica aperture bounded by and closable by two opposing lips formed from folds of lorica material. Both lips of lorica aperture thin-walled, flexible, sometimes with thickened edges or processes. Spines never present on anterior lip although edges of one or both lips may be tuberculate or serrate. Lips of aperture drawn together equally to effect closure of aperture, with neither one losing its shape in doing so. Vallum absent. Loricastome present; edge of peristomial lip of trophont adherent to posterior surface of loricastome. Posterior half of myonemal band within peristomial lip thickened. Shape and location of macronucleus differs among species.

Note on the nomenclature of the genus Lagenophrys . Jankowski (1980) created the genus Circolagenophrys for the many species of Lagenophrys that have a more or less circular outline in dorsal view and reserved the genus Lagenophrys for its type species, L. vaginicola Stein, 1852 , which has a narrow lorica that is adapted for attachment to setae of its host. Clamp (1991) considered this difference in shape of the lorica insufficient to justify this generic separation, citing ample evidence to support of his position, and made Circolagenophrys a subjective junior synonym of Lagenophrys . Despite this, Jankowski (1993) has continued to use Circolagenophrys . We find no reason to resurrect Circolagenophrys , in the absence of any evidence contradicting Clamp (1991), and will, therefore, continue to include L. turneri in Lagenophrys as defined originally by Stein (1852) and redefined by Clamp (1991). Three new species of Lagenophrys placed in Circolagenophrys by Jankowski (1993) have been treated as new combinations in the listing of species given above.
