Step-by-step explanation:
The primates that fall under the classification Haplorhine include tarsiers, New World monkeys, Old World monkeys, apes, and humans. Haplorhines are divided into two infraorders: Simiiformes (which include Platyrrhini and Catarrhini) and Tarsiiformes. Platyrrhini, or New World monkeys, are found in Central and South America and are characterized by their outward-facing nostrils and prehensile tails. Catarrhini, or Old World primates, are found in Africa and Asia and have downward-facing nostrils. They are further divided into two superfamilies: Cercopithecoidea and Hominoidea.
