Abstract
 Aphanandrium, a genus of herbs and shrubs in the Acanthaceae from the Neotropics, is reinstated based on a previous phylogenetic study, and the following new combinations are herein presented: Aphanandrium grandifolius, A. harlingii var. harlingii, A. harlingii var. longifolius, and A. nitidus. Also, Aphanandrium narupayacuensisa distinctive new species from the lowlands of northeastern Ecuador, is formally described and illustrated, and its relationship to morphologically closely related species is discussed. 

Keywords: Ecuador, Narupayacu, Neriacanthus, Neotropics
