I don't have enough confidence to venture a guess but the site below should prove to be a good resource in helping you identify them. What makes the site better than most is that he has about every wood known to man, the pictures are high quality and enlargeable, he gives useful information that can also help with identification, and due to the fact that wood of the same species can look different from tree to tree or even within samples from the same tree due to natural variations or the way it is cut, he usually provides dozens of pictures of every possible way the wood from a certain species can look.
Odd his post does not seem to exist now for some reason, but I recently bought a block of sapele for use in a cue I am having build (for the handle part) and this looks very similar, so I'd have to (4th or 5th) that hehe.
