I saw this juvenile tarantula when walking near the town of Coyolillo, Veracruz, Mexico. It was hiding under a piece of bark, fallen off a dead tree trunk nearby. It looks like the hairs on the abdomen of this species have a reddish brown color, but I doubt if its Brachypelma vagans (Mexican red-rump). I have seen quite some Brachypelma vagans species, but this tarantula spider looks different. Since I have little experience with identifying tarantulas I might be wrong.
