The Euctenizidae are a family of mygalomorph spiders. Originally created as a subfamily of Cyrtaucheniidae by Robert Raven in 1985,[1] it was established as a family by Bond et al. in 2012.[2]
They are now considered to be more closely related to Idiopidae.[2]
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
The family occurs almost exclusively in the United States and Mexico. Common U.S. genera include Myrmekiaphila, Aptostichus and Promyrmekiaphila.
