Explanation of Names
Author of the name:O. P.-Cambridge. Year first published: 1895.
5 or 6 mm
Southwestern United States from Southern California to West Texas, southward into Mexico.
The family is totally New World and consists of six-eyed haplogyne spiders that build haphazard webs in between cactus pads and in other vegetation. The web usually contains a silken and debris covered cone containing the egg sacs and into which the spider retreats. While these spiders are related to the Brown Recluse family (Sicariidae) I have never heard of their venom being toxic to humans.
