Euctenizidae

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

Euctenizidae
Aptostichus sp.
Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Chelicerata
Class: Arachnida
Order: Araneae
Infraorder: Mygalomorphae
Clade: Avicularioidea
Family: Euctenizidae
Raven, 1985
Diversity
7 genera, 83 species

Etymology

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

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 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.
