RESUMEN
The morphological analysis of the haptorial hooklets of african Polystomatidae shows that many species of larvae parasitize the tadpoles of Dicroglossus occipitalis (Günther). These multiple infestations are in contrast to the close parasitic specificity recognized by the adult Polystomes. This difference is explained by the behaviour of the host and the notion of supplying host is introduced.

Metapolystoma cachani a parasite of Ptychadena longirostris (Peters) has been discovered in the Ivory coast. Its life cycle is the first to involve both the possibility of an internal cycle in the bladder of the adult Amphibian and a neotenical reproduction on the gills of the Tadpole. This double process is the link between the Monogeneans which are only parasites of aquatic hosts and those which are adapted to terrestrial hosts. Its place is therefore essential in the phylogeny of Polystomatidae.
