The Cranaidae are a family of neotropical harvestmen within the suborder Laniatores.

Name

The name of the type genus is derived from Cranaus, the successor of Cecrops I as king of Attica in Greek mythology.[1]

Description

Body length ranges from about six to sixteen millimeters. The color normally ranges from brown to black greenish, with the legs sometimes lighter to yellowish. Some species feature white stripes on some regions.[1]

Distribution

Most species are found in northern South America, with few species found in Panama and Costa Rica. The diversity of the family is probably explained by the diversity of habitats in the cloud forests of Ecuador and Colombia, ranging from elevations of 500 to 3,500 m. Some species were even collected from elevations as high as 5,000 meters.[1]

Relationships

The four subfamilies constituting the Cranaidae were transferred from Gonyleptidae by Kury (1994), erecting it as a sister group to Cosmetidae and Gonyleptidae. Cranainae and Stygnocranainae are probably closely related.[2]
