Could be Sericopelma rubronitens
The carapace markings make me think velvetosoma.Panama and Ecuador are not geographically close. Not enough for a tarantula to have an undiscovered range, anyway. They are not masters of dispersal.
This is a mature male, and I would compare to Pamphobeteus petersi or perhaps Megaphobema velvetosoma. Peters notes in his description of P. petersi that specimens of the two species were mixed with one another, so they were difficult to distinguish (not mixed as in bred, but placed together as collected items of the same species).
