Male Hacklemesh Weaver Callobius Spider
Hacklemesh Weaver spiders are part of the Amaurobiidae family. They believe it is part of the Callobius genus. Apparently it is hard to know what TYPE of Hacklemesh Weaver spider you have (i.e. what specific species) because they look almost identical at this level. We are happy just to know we have Hacklemesh weavers!
This page is all about MALE Hacklemesh Callobius spiders we have seen. They have a much smaller abdomen than the females do. Also, males when they are sexually mature have a "boxing glove" front to their palps, which females do not have.
From John S. on BugGuide: "Your third picture gives a good view of the tibial apophyses (the prongs sticking out on the segment above the "boxing glove" part of the palps) when I enlarge it. They are long and three-pointed, which is typical for this genus (the middle prong is blunter and shorter than the outside prongs, and is harder to see in the picture). In Coras they are not so large." So this is a way to tell between the Callobius and the Cora.
