in the class

Opecoelidae Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes.Bray, Rodney A., Cribb, Thomas H., Littlewood, D. Timothy J. & Waesch ...

. It is synonymous with ''Allostenopera'' Baeva, 1968, ''Metahelicometra'' Yamaguti, 1971, and ''Stenopera'' Manter, 1933. Its type species is ''H. fasciata'' (Rudolphi, 1819). They are distinguished by their unique spiral uterus, from which their name is derived.
