Summary
Microlicia donii is described, illustrated, and its conservation status is assessed using the IUCN criteria. The proposed new species is compared with two probable relatives, M. pusilla Cogn. and M. ciliatoglandulosa R.Romero. The georeferenced occurrences of M. donii are mapped. Microlicia donii populations may be threatened because they occur outside the borders of the Serra do Cabral State Park.

Microlicia donii Fidanza & R.Pacifico sp. nov.
Etymology. Microlicia donii is named in honour of the Scottish botanist David Don (1799 – 1841), who described many species and several genera in Melastomataceae, including Microlicia (Don 1823). David Don worked as assistant in the Lambertian Herbarium from 1820 to 1836 and also made important contributions to pine taxonomy (Miller 1970).
Nomenclatural note. Microlicia donii was cited as M. lanceaefolia in Rodrigues (2005). However, the epithet lanceaefolia was not effectively published. We have avoided using this name due to its similarity to M. lanceaeflora Mart. & Schrank ex DC
