This is a Trachelas from the family Trachelidae. Some common names are broad faced sac Spider, pacific sac Spider. I can’t help with exact species but it’s Genus is definitely Trachelas. This male is young and wandering probably looking for food. They aren’t aggressive and aren’t medically significant to humans. Your area and mine as well have a couple species but it’s impossible to tell them apart to species level without microscope pictures. I like having Trachelas around and sadly haven’t seen any yet this season. I hope this helps
Thank you for the info. A friend of mine in Texas also believed it to be a sac spider. Never seen anything like it before.
You’re welcome
https://spiderid.com/picture/42565/ Here’s a way to (sometimes) ID a Broad-faced Sac Spider. This is one of my pics, I thought it is cool how the eyes are in two broad bands of 4 that wrap around the face. Most of the eyes aren’t usually visible in photos.
Wonderful Trachelas picture!! I have some very good pictures of Trachelas as well but my mentor insists they are not able to be distinguished unless genitalia are compared under a microscope. I always try to document any characteristics and compare because although in some cases yes that’s the only way I believe with macro photography and microscope photography we most likely can put a live spider to species with pictures and it’s a kind of personal mission for me to try to prove that
