ABSTRACT
A new terebratulid brachiopod species, Neopaulinella noguerasensis, has been identified from the Nogueras Formation of the Eastern Iberian Chains (Spain). It is compared with the other known species of Neopaulinella from France and Spain, N. guerangeri and N. gaudryi, from which it differs in size of costae, dental plates, and dorsal adductor field including the dorsal median septum. Digitized three-dimensional reconstructions of the internal shell and the loop of the new species are presented. The life habit of N. noguerasensis is briefly discussed regarding its palaeoecological environment. The cladistical analysis show an equal relationship to the other species of Neopaulinella. The phylogeny of the genus and migration paths of its species are demonstrated. The palaeobiogeographical distribution of Neopaulinella reflects the Early Devonian provincialism and suggests a migration path between Western and Central Europe during Siegenian time.
