Recent collections of Sphaerosepalaceae from NE Madagascar represent two new species of Rhopalocarpus Bojer. In the case of R. mollis, fruiting material from E of Mandritsara confirms previous doubts concerning the disjunct occurrence of R. triplinervius in the region, which was based on a single sterile specimen. Two fruiting collections from between Sambava and Vohemar represent the first material of R. randrianaivoi, reaffirming the importance of the region as a center of local endemism requiring immediate conservation action. The two new species are distinguished by their leaf size and shape, venation, and fruit surface.
