Looks like

I would place it in Antrodiae
I would place it in Antrodiaetidae. I base this on the presence of tergites, elevated wide pars cephalica, and the appearance of the thoracic groove. Can I assume that the size mentioned included the legs and doesn't refer to the body only?

Definitely Antrodiaetus
