Diversity
7 genera, c. 70 species

The Euctenizidae (formerly Cyrtaucheniidae subfamily Euctenizinae) are a family of mygalomorph spiders. They are now considered to be more closely related to Idiopidae.

Biology

Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. The biology of nearly all the species is poorly known.

Distribution

The family occurs almost exclusively in the United States and Mexico. Common U.S. genera include Myrmekiaphila, Aptostichus and Promyrmekiaphila.
