Tarantulas native to Ecuador?

I recently turned down an article because I couldn't find specific information on tarantulas from Ecuador. (I write online informational and how-to articles.)

It's been bugging (no pun intended) me and I thought I'd ask all of you spider/tarantula experts about the variety of South American tarantulas. I know about the Goliath bird-eating tarantula, and the one with blue fangs, but I'm sure that there's several species native to Ecuador.

Also, it's my understanding that tarantulas generally don't bite their owners as long as they're treated gently. Do you find that true or are some species more aggressive than others?

Thank you in advance!
