Members of the family Protorhyphidae are known only from extinct taxa. The family was based originally on the genus Protorhyphus Handlirsch from Lower Jurassic deposits of Germany. Subsequently, four more genera have been added to the family, all from the Jurassic. Rohdendorf (1964) placed the family between the Oligophrynidae and Olbiogastridae (both considered here in the family Anisopodidae) of his Superfamily Rhyphidea.
In addition to the determined forms listed below, Jarzembowski (1978) mentioned an undetermined specimen from the Lower Jurassic of Britain that may belong to this family.
