Haplorhini

Simiiformes / Anthropoidea

Tarsiiformes. Haplorhini. The haplorhines, the "dry-nosed" primates (the Greek name means "simple-nosed"), are members of the clade Haplorhini: the tarsiers and the anthropoids.

The anthropoids are the catarrhines (Old World monkeys and apes, including humans) and the platyrrhines (New World monkeys). The omomyids are an extinct group of prosimians, believed to be more closely related to the tarsiers than to any strepsirrhines, and are considered the most primitive haplorhines. Haplorhines share a number of derived features that distinguish them from the strepsirrhine "wet-nosed" primates (whose Greek name means "curved nose"), the other suborder of primates from which they parted in evolution some 63 million years ago.
