Une hypothèse sur l’origine pacifique du genre Diplozoon (Monogenea, Polyopistho-cotylea) est proposée. Elle est suggérée par les affinités morpho-anatomiques déjà relevées avec le genre Octomacrum mais aussi par une analyse de la répartition géographique de ces parasites et de leurs hôtes respectifs.
Abstract
The evolutionary geographic origin of Diplozoon and Octomacrum (Monogenea, Polyopisthocotylea) is discussed. Diplozoon occurs in Eurasia and Africa, whereas the distribution of Octomacrum is limited to North-America. These two monogeneans likely had a common progenitor originating from the Pacific. This hypothesis is suggested by the morpho-anatomical resemblances between Diplozoon and Octomacrum and by the analysis of their geographic distribution.
