Caddidae is a family of harvestmen with 15 known species, the only family of the Eupnoi superfamily Caddoidea.

They have mostly a body length between one and three millimetersaut|Pinto-da-Rocha, Ricardo & Gruber, Jürgen (2007): Caddidae Banks, 1893. In: Pinto-da-Rocha "et al.." 2007: 115ff] .

Distribution

Caddids are widely but discontinuously distributed. In the subfamily Caddinae, "Caddella" is endemic to southern South Africa, while "Caddo" is found in eastern North America and Japan with the Kuril Islands. In the other subfamily, Acropsopilioninae, "Hesperopilio" occurs in western Australia and Chile, "Acropsopilio" is found in Japan, eastern North America, Central to South America, eastern Australia and New Zealand. "Austropsopilio" is found in eastern Australia, Tasmania and Chile. This complex pattern suggests that separation occurred in several steps: during the Neogene (eastern North America and Japan); at the beginning or before the Tertiary (South America and Australia), and during the time of Gondwana (Africa and Australia).

Name

The family name is derived from "Caddo", a North American indigenous culture, people and language.
