Boyania kenwurdackii (Melastomataceae, Sonerileae) is described from moist forests in Guyana. It is the third species in the genus and most closely resembles the other species that occurs in Guyana, B. ayangannae, but differs on flower merosity, indumentum, petal and anther size and morphology. The new species is illustrated and scanning electron microscopy photographs of the seeds are provided, as well as a distribution map for both species present in Guyana.
