Structures argyrophiles superficielles du miracidium et de la cercaire deParamphistomum microbothrioidesPrice et Mac Intosh, 1944(Trematoda, Paramphistomidae)

Abstract

R É SU M É . Le Superficial argentophilic structures of the miracidium are identical to those observed in the other species of the genus. On the other hand, on the terebratorium, they are different from those of the miracidium of Calicophoron calicophorum.Cercarial papillae are rarely symmetrical and their number varies according to specimens. However differences between the species are obvious.If Paramphistomum microbothrioides, P. microbothrium and P. daubneyi are related by acetabular papillae, the number of lateral papillae and the caudal chaetotaxy allow to distinguish these three species.*
