[Extract] The Opisthotrematidae Poche, 1926 is a small family of monostome digeneans, in the superfamily Pronocephaloidea Looss, 1902, restricted to marine mammals of the Order Sirenia. Opisthotrematids inhabit a variety of sites in the lumen and walls of the digestive tract, the pancreatic ducts, gall-bladder and respiratory tract. They are unusual in that the genital pores are at the posterior end of the body.

Poche (1926) erected the family to contain the genus Opisthotrema Fischer, 1883. Blair (1981), following earlier authors, regarded the type-species of Opisthotrema as O. dujonis (Leuckart, 1874) Price, 1932. However, Article 67.1 and Recommendation 67B of the ICZN make it clear that the type-species is O. cochleare Fischer, 1883, a junior synonym of O. dujonis (Leuckart, 18(4). Although some authors have preferred to reduce the Opisthotrematidae to subfamily status within the Notocotylidae Luhe, 1909 (e.g. Szidat, 1939) or the Pronocephalidae Looss. 1902 (e.g. Ruiz, 1946; Crusz & Fernand, 1954), most classifications (e.g. Skrjabin, 1953, 1964; Yamaguti,1958,1971; Groschaft & Tenora, 1981) have retained family rank for the taxon.
