A new species, Hoya mappigera is described and illustrated. Despite its oldest herbarium record being more one century old it has been confused up to now with either the co‐occurring Hoya campanulata or the Singapore endemic Hoya wallichii because of the common presence of showy, broadly campanulate corollas. A close examination of the corona morphology revealed that the closest morphological match is neither of these species but instead the recently described Brunei endemic Hoya wongii . The two species can be easily separated because the latter has bi‐toothed inner corona lobes whereas the new species presents sulcate inner corona lobes ending in an acuminate tip.
