in Cornejo, Wasshausen, Exe et Johnson, 2023. 

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 narupayacuensis, a 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
