Two new species of the Neotropical genus Acinaces (A. nataliae and A. kumeralis) from Peru are described, diagnosed and illustrated. The following new status is proposed: A. stroheekeri Tomaszewska, 2003 ( =A. lebasii stroheckeri Tomaszewska, 2003). Notes on the colour variation of A. laceratus, the most variable species of the genus are provided. The key to the known species of the genus is updated.
