Abstract

A study of the morphology of some isopod taxa suggests that Protallocoxoidea (Asellota) and Plakarthriidae (Flabellifera) represent the most ancient groups of extant isopods. The main reason is the presence of free coxae of the first pair of peraeopods. The Stenetrioidea (Asellota) probably evolved from ancestors like Protallocoxa. The present distribution of the three taxa does not reveal the center of their evolution. Studies of cave-living oniscoids in the New World and Europe combined with our knowledge of the development of the Atlantic suggest a time-scale of 150 million years for the evolution of taxa to the subfamily level. Whether or not this time-scale is applicable also for marine isopods is unknown. The evolution of the isopods as well as the origin of deep-sea species is still poorly understood.
