Synonyms and other taxonomic changes
Although these spiders have been placed in a cribellate family, they do not have a cribellum. See discussion here
on page 25 (23). Coelotes, Coras
, and Wadotes
are ecribellate amaurobiids (from link).
Explanation of Names
From Vergil's Aeneid, one of the Argive twins.(1)
15 species in the USA and Canada.
Howell and Jenkins state that "C medicinalis builds an extensive, broad, platform-like web that is equipped with a tubular or funnel retreat. Their webs are often constructed beneath overhanging rock ledges where the platform of the web sags somewhat."
Exact distribution within these countries will be added when time permits.

This genus was moved from Amaurobiidae in 2011.
Page origination: Eric suggested the possibility of these being in the genus Coras. Images are very similar to those in Howell and Jenkins. We've gathered the images here to hold them until ID can be worked out.
how to know the spiders gives these few distinctions: Coras has robust chelicerae and the anterior median eyes usually larger than the anterior laterals. Tegenaria does not have robust chelicerae, anterior median eyes not larger than the laterals(usually smaller), posterior median eyes are very little smaller than the posterior laterals, and the posterior eye row is slightly procurved.
