Not a genus: an infraorder, the entire trapdoor-tarantula-funnelweb branch of spiders, and a key at this rank means a listing that could be almost anything with fangs that strike downward.
This page exists to explain that. Material filed here is unidentified mygalomorph stock, burrowing, silk-lining, fast at the burrow mouth, and treated with blanket caution: venom undocumented because the animal is unidentified, no handling on principle.
A rank this broad is a catalog problem wearing a listing, and the practical advice is photographic: the images carry whatever identification exists. Prices here float free of any anchor at all, which is the purest version of the site's recurring lesson about unanchored labels.
