The identity of this sp is not clear, since the type at (B), was likely destroyed. Even though Perrier (1932) made the combination P. schoenlankii var. madagascariensis, he did not cite the Rutenberg specimen, but he clearly belved it to be part of P. schoenlankii. Therefore, unless a duplicate of the type is located, the taxonomic affinity of P. madagascariensis will remain unknown. Paiva (1998) made the same observation.
