AB The Recent planktonic larvae of the polychaete spionids are some of the mostwidespread and abundant group of coastal meroplankton worldwide. To study thepossible co-migration of biotic partners and determine whether they were host-specific,the type of biotic relationship between hosts and borers of an Upper Ordovician Peruvianbrachiopod collection from the Proto-Andean margin of Gondwana was re-exanimatedand compared with material from Wales (Avalonia). The species list studied iscomposed of Colaptomena expansa (41%), Heterorthis retrorsistria (24%), Horderleyellachacaltanai (19%), Drabovinella minuscula (13%), and Dinorthis cf. flabellulum (3%)and coincides closely with that of the Dinorthis community described in the Caradocseries of North Wales. The borings attributed to these spionids have been identified asPalaeosabella prisca only present in the valves of Colaptomena expansa and Heterorthisretrorsistria. All the studied valves are disarticulated, with very low fragmentation andare randomly oriented in a context below the fair-weather wave base. The settlinglarvae would feed on their brachiopod host soft parts at an early stage, being thebiotic interaction initially of the parasitic type. Since Palaeosabella borings from Peruand Wales are identical, as well as the species specificity of their producers with theirbrachiopod hosts, it can be concluded that the same spionid annelid species producedthem. The Southern Westerlies current that connected the Proto-Andean margin ofGondwana with Avalonia must have been responsible for transporting the larvae ofannelids and brachiopods in what had to be a successful biotic relationship over a greattransoceanic distance.
