What kind of thing is this?

Both of the photos live in Thailand.
I'm curious about these full names.
The seller is two trapdoor spiders, right?

I saw you posted this in the true spider section as well. That was smart because i'm sure it is not a tarantula.

The first one is an absolutely fascinating spider from the very ancient group of Liphistiidae, the only spiders that still have a segmented opisthosoma! (Evolution at work: spiders are derived from arthropoda with a segmented body.) Very, very little is known about them, since they live hidden away in burrows. I can't tell you the species and doubt that anyone can, but here's a publication about them:

If you can actually buy that spider do it by all means, because that's something real special. They live a lot like trap door spiders do, but they are not in any way related.

@The Snark - think you could chime in on this one given the locality of these spiders?
