Resumen:
Species allocated to the digenean genera Enenterum Linton, 1910; Jeancadenatia Dollfus, 1946; Cadenatella Dollfus, 1946; and Koseiria form a clade within the Lepocreadiidae whose sister group is a clade comprising Neoallolepidapedon Yamaguti, 1965, Callogonotrema, Oshmarin, 1965, Allolepidapedon Yamaguti, 1940, and Bulbocirrus Oshmarin, 1965. Phylogenetic analysis of the Enenterinae based on comparative morphology, produced one most parsimonious tree with a consistency, index of 0.72. Cadenatella is paraphyletic. Only 15.3% of character changes are evolutionary, losses, supporting earlier reports that parasitic platyhelminths have experienced little secondary simplification during their evolutionary history. The Enenterinae appears to have originated in the Pacific Ocean, becoming associated with kyphosid fishes as a result of an ancient host switch. Subsequent evolutionary diversification reflects widespread geographical dispersal, consistent with the natural history, of kyphosids.
