Eriosemopsis is a monotypic genus of flowering plants in the Rubiaceae family. It was descripted by Walter Robyns in 1928 and no changes have been made since then. The genus contains only one species, viz. Eriosemopsis subanisophylla, which is endemic to KwaZulu-Natal, South Africa. The species is morphologically similar to the species Pygmaeothamnus zeyheri but differs by having a thick indumentum, raised venation and elliptical leaves.
