Cypraeovula fuscorubra elsorum n. ssp. in the Danger Point area on the Cape Overberg region coast differs from the nominate C. fuscorubra fuscorubra (Shaw 1909) which is confined to the Cape Peninsula west coast. The shell of fuscorubra elsorum is generally smaller, has longer extending riblets of the columellar teeth, less developed marginal and ventral callosities, and a more exposed spire. Analysis of the fuscorubra elsorum COI gene shows considerable differences to its western sister, C. fuscorubra fuscorubra. A 95 km long coastal distribution gap separates the known distribution of both subspecies. C. fuscorubra elsorum is also compared to C. fuscodentata grohorum Lorenz 2002 occupying the apparent range interval. Lorenz (2002, 2017, 2018) applied the name gondwanalandensis Burgess 1970 to the new subspecies and this oversight is corrected herein.
