Peperomia aguilae Trel. &Yunck. and Peperomia gutierrezana Trel. & Yunck. turned out to be the same species. As they were published in the same publication, none of the names has priority and the first author proposing the legitimate name and its synonym has to be followed. In this case Steyermark (1984) put P. aguilae in synonymy of P. gutierezana. The proposal of Bono (1996), to consider P. guitierrezana as a synonym of P. aguilae has to be rejected [Mathieu, 2006].
