Brachypelma auratum

Brachypelma auratum is a tarantula endemic to the Mexican states of Guerrero and Michoacan. It resembles the well known Mexican red-kneed spider, Brachypelma smithi, though it is darker with more discrete red striations on the patella, a marking that gives it its common name, the flame knee. Because of its close similarity to B. smithi, it was not recognized as a distinct species until 1992. It has been found living communally with a small frog, Eleutherodactylus occidentalis.
