What did I find?

Hi
I work in a greenhouse in The Netherlands, where we import plants from South America and Asia.
Today I found 2 spiders which I couldn't identify.

The first one was found in a plant from Costa Rica. The little guy/girl made a web there (It was a web like a cartwheel). It's about 0,5 cm in BL (= 0,2 inch)
The second one came from a crate of plants from Thailand or Taiwan (can't remember). All I know is that is one of those spiders who look like an ant. It's less than 0,5 cm (0,2 inch) in BL.
Sorry for the crappy pics, was the best I could get.

I think the name of the ant spider is Myrmarachne plataleoides. It's the only one I could find. Don't know if there are more species of this.
And for the other one, I think I've narrowed it down to either Uloborus walckenaerius or Uloborus plumipes.

First one is indeed Urobolus sp. Probably U. plumipes.
Apparently these are quite common in greenhouses. I found one on a plant I had bought a while ago too.
