Oops I meant to say T. marcianus X texas sorry guys. When I bought them they were three years old and the man selling them explained that a few marcianus cages that were on the same rack all crashed so the the garters from those cages had to be placed with the texas garters and later that year that year they had babies so the man selling the garters assumed that the were crosses of the two. Also the man did'nt give me any scientific names so the texas part might not be T. annectans
