Abstract
Abuta alto-macahensis is described and illustrated as a new species restricted to mountains of the State of Rio de Janeiro, southeastern Brazil. It is morphologically similar to Abuta rufescens, but it can be distinguished by the leaf blades adpressed tomentose abaxially, and drupelets ≥ 5 cm long, glabrous. Furthermore, taxonomic notes, preliminary conservation status, an identification key, and a distribution map of this new species are presented.
