At this moment I have three tarantula spiders. Two resemble the Costa Rican Tiger-Rump (Cyclosternum fasciatum) but where found in Veracruz, Mexico. It might be very well the case that Costa Rican Tiger-rump tarantulas one can buy in a pet shop are actually originally coming from Mexico.
For a short wile I also had a Veracruz Red Rump (Tliltocatl kahlenbergi) tarantula, but it died shortly after it made a sperm web. Male tarantulas live relatively short once they are adult so maybe it died from old age.
During several field trips in Veracruz I have seen Red Rump tarantulas living very close to the Tiger-rump look-a-like, sometimes even living together under the very same stone. To make things even more interesting, I also have seen Florida bark scorpions (Centruroides gracilis) living under the same rock. And recently even a couple of small Túngara frogs, (Engystomops pustulosus), sharing the burrow.
MexIT is a blog I keep, and it has several entries regarding mexican tarantula spiders, pictures and info on their habitat.
