My first thought was maybe Philodendron (Philodendron plowmanii) but the leaves aren't right for that one. We don't have any database photos of Philodendron ernestii but googling for images looks like that one might be a contender. I'm just not all that familiar with Aroids but I bet @Gina1960 might be able to help.
