Unfortunately, you can't search for 3-letter words via the AB search function. The species in the genus currently are:
Ami amazonica -- Colombia Ami bladesi -- Panama Ami caxiuana -- Brazil Ami obscura -- Colombia Ami pijaos -- Colombia Ami weinmanni -- Venezuela Ami yupanquii -- Ecuador
All species were described in 2008, except A. obscura, which is known to science since 1875, but was placed in the wrong genus. Ami species have modified type I urticating hairs, and quite unique looking spermathecae. They are terrestrial as far as I know. Based on the so far described specimens, body length in the genus is 17.5 - 33.2 mm (~0.7" - 1.3"). If you want to read the article, PM me with an e-mail address. About their captive care I can't really say anything, because I'm not keeping any.

I found your information very helpful in making a decision.
I have an opportunity to purchase one, and I would like to know more about this genus. but, as it seems these are relatively new to the hobby. So I'll post what I can.
