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

Etymology

edit

The name comes from the Greek prefix εὖ- (eu-), meaning "valuable" or "good", which had been thought that the family Ctenizidae possess these traits.[1]

Biology

edit

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

Distribution

edit

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