• Resumen

  • Recent studies and a review of the original types of Bolivina afra (Reyment) reveal three distinct species hitherto named as B. afra and each characterised by a different ornament. One new subspecies of B. afra is described. A new age range - Upper Cretaceous - Lower Paleocene is proposed.
