Abstract
Odontopleurid trilobite remains from the latest Eifelian to earliest Givetian Hanonet Formation in the Resteigne quarry, southern Belgium, are described and assigned to a new species Radiaspis taghonorum. Although the pygidium of R. taghonorum is similar to that of some Eifelian congeners, its cephalon is markedly different. The Hanonet Formation bears a trilobite fauna that is characteristic of the Ardenno-Rhenish Mountains. The late Eifelian–earliest Givetian interval is associated with a trilobite diversity increase in Belgium and migrations between Belgium, Germany and Morocco.
