Which other primates are closely grouped with the woolly monkeys within the Family Atelidae?

Answer

Spider monkeys and howler monkeys

The family Atelidae groups together several large, specialized New World primates, indicating a shared, relatively recent evolutionary history focused on highly developed arboreal capabilities. The three primary components of this family are the woolly monkeys, the spider monkeys, and the howler monkeys. Sharing this familial classification suggests they all inherited core adaptations for canopy life, such as the prehensile tail. While spider monkeys are noted for their slender builds and howlers for their vocalizations, and woolly monkeys for their dense fur and robust limbs, their common ancestry within Atelidae links them together against other primate families.
