Pseudopontia paradoxa is a species of butterfly found only in wet forests of tropical Africa. It was traditionally thought to be the only species (monotypic) in the genusPseudopontia and the subfamilyPseudopontiinae. However, a recent study showed there are at least five species of Pseudopontia which can be distinguished genetically and by details of wing veins. Each is found primarily in a different part of Africa, though several of the species have overlapping geographic distributions.
It is considered paradoxical because, despite being a true butterfly (Papilionoidea), its antennae do not have the characteristic clubbed ends which are otherwise diagnostic of butterflies (Rhopalocera).
