This tarantula species looks extremely similar to the Costa Rican tiger rump (Cyclosternum fasciatum), but it might be very well a different species. Yet I suspect that this Mexican tarantula is often sold in the trade as a Costa Rican tiger rump. In my experience this species is less docile compared to Brachypelma sp. I often encounter in the wild, but still very easy to handle.
The tarantula is sitting on the underside of the stone it was hiding under.
