Slakoth is definitely a sloth. Vigoroth and Slaking are arguably primates. I would argue Darumaka and Darumanitan are primates given their orangutan situation but I can see that being arguable. Subsequent generations have also introduced Annihilape, Zarude, Grafaiai and Munkidori, all primates.
Also maybe specify non-human primate, given Mr. Mime, Jinx, etc. are all human-like pokemon.
