[Coexistence of neoteny and an internal cycle a polystomatid (Monogenea)].
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.
