They have the Aipom of the region... well the Aipoms.
A new image has just leaked onto 2ch from as a yet unknown publication which features a new monkey Pokemon. This monkey is a similar monkey to Yanappu and is blue. According to the poster on 2ch, the monkeys form a trio of Pokemon called Yanappu, which we know is grass, Hiyappu, which is water, and Baoppu, which is of the fire-type. We're unsure as to whether they have any pure differences but we'll bring more on this as and when it comes.
So it sounds like we got ourselves a new monkey trio... :o
