Abstract
Justicia Linnaeus (1753: 15) is the largest genus in the family Acanthaceae with about 700 species mainly distributed in the tropical and subtropical regions of the world (Mabberley 2017). After a through scrutiny of literature and type specimens, it was found that the name of a Brazilian endemic species, Justicia fittonioides Lindau (1904: 411) is illegitimate as it is a later homonym of an African endemic species, Justicia fittonioides Moore (1878: 134). Therefore, a new name is proposed here in accordance with the article 53.1 of Shenzhen Code (Turland et al. 2018).
