Overview

Taxonomy

The Suborder Haplorrhini is further organized into finer groupings including:

• Infraorder (2): Simiiformes · Tarsiiformes
• Parvorder (2): Catarrhini · Platyrrhini
• Series (1): Amniota
• Family (14): Afrotarsiidae · Aotidae · Atelidae · Carpolestidae · Cebidae · Cercopithecidae · Hominidae · Hylobatidae · Microchoeridae · Omomyidae · Pitheciidae · Pliopithecidae · Proconsulidae · Tarsiidae

Families

Afrotarsiidae

[more]

Aotidae

The Night monkeys, also known as the Owl monkeys or Douroucoulis, are the members of the genus Aotus of New World monkeys (monotypic in family Aotidae). They are widely distributed in the forests of Central and South America, from Panama south to Paraguay and northern Argentina. The species that live at higher elevations tend to have thicker fur than the monkeys at sea level. The genus name means "earless"; they have ears, of course, but the external ears are tiny and hard to see. Night monkeys have big brown eyes and therefore have increased ability to be active at night. They are called night monkeys because all species are active at night and are in fact the only truly nocturnal monkeys. (An exception is the subspecies A. a. azarae, which is cathemeral, active during both daylight and nighttime hours.) Both male and female Night Monkeys weigh almost the same amount. For example, in one of these Night Monkeys, A. azarae, the male weighs 2.76 pounds while the female weighs 2.75 pounds. [more]

Atelidae

The Atelidae are one of the four families of New World monkeys now recognised. Formerly they were included in the family Cebidae. Atelids are general larger monkeys, and the family includes the howler, spider and woolly monkeys. They are found throughout the forested regions of Central and South America, from Mexico to northern Argentina. [more]

Carpolestidae

Carpolestidae is a family of primate-like plesiadapiformes that were prevalent in North America and Asia from the mid Paleocene through the early Eocene. Typically, they are characterized by two large upper posterior premolars and one large lower posterior premolar. They weighed about 20-150g, and were about the size of a mouse. Though they come from the order, Plesiadapiformes that may have given rise to the primate order, carpolestids are too specialized and derived to be ancestors of primates. [more]

Cebidae

The Cebidae form one of the four families of New World monkeys now recognised. It includes the marmosets, tamarins, capuchin monkeys and squirrel monkeys. They are found throughout tropical and subtropical South and Central America. [more]

Cercopithecidae

The Old World monkeys or Cercopithecidae are a group of primates, falling in the superfamily Cercopithecoidea in the clade Catarrhini. The Old World monkeys are native to Africa and Asia today, inhabiting a range of environments from tropical rain forest to savanna, scrubland, and mountainous terrain, and are also known from Europe in the fossil record. However, a (possibly introduced) free-roaming group of monkeys still survives in Gibraltar (Europe) to this day. They include many of the most familiar species of non-human primates such as baboons and macaques. [more]

Hominidae

The great apes are the members of the biological family Hominidae which includes humans, chimpanzees, gorillas, and orangutans. [more]

Hylobatidae

Gibbons are the small apes in the family Hylobatidae. The family is divided into four genera based on their diploid chromosome number: Hylobates (44), Hoolock (38), Nomascus (52), and Symphalangus (50). The extinct Bunopithecus sericus is a gibbon or gibbon-like ape which, until recently, was thought to be closely related to the Hoolock gibbons. Gibbons occur in tropical and subtropical rainforests from northeast India to Indonesia and north to southern China, including the islands of Sumatra, Borneo and Java. [more]

Microchoeridae

[more]

Omomyidae

Omomyids (members of the taxon Omomyidae) are a diverse group of extinct primates that radiated during the Eocene epoch between about 55 and 34 million years ago. Fossils of omomyids are found in North America, Europe, Asia, and possibly Africa. Omomyids are one of two groups of Eocene primates with a geographic distribution spanning holarctic continents, the other being the adapids (Adapidae). Early representatives of the Omomyidae and Adapidae appear suddenly at the beginning of the Eocene of North America, Europe, and Asia, and are the earliest known crown primates. [more]

Pitheciidae

The Pitheciidae are one of the four families of New World monkeys now recognised. Formerly they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazonia region of Brazil, with some being found from Colombia in the north to Bolivia in the south. [more]

Pliopithecidae

[more]

Proconsulidae

[more]

Tarsiidae

Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. Although the group was once more widespread, all the species living today are found in the islands of Southeast Asia. [more]

At least 20 species and subspecies belong to the Family Tarsiidae.
