Resumen
Pachyoliva Olsson, 1956, previously considered a subgenus of Olivella (Olividae: Olivellinae), is characterized by a unique propodial morphology that enables a suspension-feeding lifestyle. As shown here, radulae of the two extant Pachyoliva species carry rachidian teeth with convex cusp-bearing edges, differing from those of other Olivellinae. While its functional significance for the unusual feeding mode remains unclear, the distinctive radular morphology supports elevation of Pachyoliva to full generic status.
