Primate Like Aliens

2 life forms of my planet Chrysaoirs, that I am currently working on. These 2 creatures belong to the Hylipithecidae family.
Neomandrilpedates Pagodialle- (top one) commonly called Pagodanan, this Vormolian bears so many similarities to Terran gorillas and mandrills. The males have brightly colored faces and crests. Females are dull and smaller crests. Mostly carnivourous they hunt smaller Vormolians and Fanheads that live in the pagoda forests.
Neohyladrilpedates agilis-(bottom one) Dimadan are like gibbons of Chrysaoirs. They live high up in the canopy feeding on the fruit and vegetation that grow there. They have body strutcture that came from a common ancsestor that it shares with all Vormolians.
