The benthonic foraminiferid Osangularia schloenbachi (Reuss, 1863) is an established index taxon for Albian to Aptian age sediments worldwide. It is a very useful marker species commonly encountered in cuttings sampled from offshore boreholes on the north-west European continental shelf. However, despite its biostratigraphical utility there is no known holotype for this species. This short article rectifies this taxonomic point of order by erecting a neotype for the species.
