Procyonidae is a New World family of the order Carnivora. It comprises the raccoons, coatis, kinkajous, olingos, olinguitos, ringtails, and cacomistles. Procyonids inhabit a wide range of environments and are generally omnivorous.

Characteristics

Procyonids are relatively small animals, with generally slender bodies and long tails, though the common raccoon tends to be bulky.

Because of their general build, the Procyonidae are often popularly viewed as smaller cousins of the bear family. This is apparent in their German names: a raccoon is called a Waschbär (washing bear, as he "washes" his food before eating), a coati is a Nasenbär (nose-bear), while a kinkajou is a Honigbär (honey-bear). Dutch follows suit, calling the animals wasbeer, neusbeer and rolstaartbeer respectively. However, it is now believed that procyonids are more closely related to mustelids than to bears.

Due to their omnivorous diet, procyonids have lost some of the adaptations for flesh-eating found in their carnivorous relatives. While they do have carnassial teeth, these are poorly developed in most species, especially the raccoons.

Classification

There has been considerable historical uncertainty over the correct classification of several members. The red panda was previously classified in this family, but it is now classified in its own family, the Ailuridae, based on molecular biology studies. The status of the various olingos was disputed: some regarded them all as subspecies of Bassaricyon gabbii before DNA sequence data demonstrated otherwise.

The traditional classification scheme shown below on the left predates the recent revolution in our understanding of procyonid phylogeny based on genetic sequence analysis. This outdated classification groups kinkajous and olingos together on the basis of similarities in morphology that are now known to be an example of parallel evolution; similarly, coatis are shown as being most closely related to raccoons, when in fact they are closest to olingos. Below right is a cladogram showing the results of the recent molecular studies. Genus Nasuella was not included in these studies, but in a separate study was found to nest within Nasua.
