I tried to look it up once. It seemed closest to Pterinochilus.
I just found this site on a search:
http://tarantulas.differentdawn.com/unicorn/uni.html
It says near the bottom that all Ceratogyrus sp. have a light band
across their underside (see pic). I don't recall her having that, but
then I don't go around flipping baboon spiders over!
