A new species of Minnivola is described, from late Miocene lime-stone occurring in the valley of the Umfolosi River in Zululand, South Africa. The species extends the known range of the genus into the East African region and is distinguished by the presence on the adult right valve of about thirty-two ridges arranged in bundles of four, with prominent grooves between the bundles.
