I believe this is Euagrus chisoseus. They are the most common species of mygalomorph i find on our property. You can find one under almost every rock. They make very large webs for their size, and usually build a tunnel as well. I was raking leaves when I turned over a rock and found this little one, which I believe may be gravid, given her large abdomen size and the time of year. I didn't have a container when I caught her, and was holding her for about 10 minutes in my closed hand (with enough room for her to move around, and some dirt). When I open my hand she had started making a web between three of my fingers. You can see she has the long spinnerets seen on this species and other Dipluridae.
