The folding trapdoor spiders (Antrodiaetidae) are a small spider family with about 30 species in three genera. They are related to the Atypidae (atypical tarantulas).

[edit] Distribution

Antrodiaetids are found almost exclusively in the USA, in the west (California, Arizona, Nevada, Utah, Oregon, Washington, Idaho), the midwest (Missouri, Kansas, Arkansas, Illinois), and the east (centered in the Appalachian mountains).^[1]

Two species (Antrodiaetus roretzi and A. yesoensis) are endemic to Japan. They are considered relict species; two separate vicariance events probably led to the evolution of these two species (Miller & Coyle, 1996).

The three species of the former genus Atypoides are now included in the genus Antrodiaetus (Hendrixson & Bond, 2007).
