I'm not familiar with M. capita. Based on the few images I found, your coral doesn't appear to even bear the growth pattern of M. capita so I think you can rule that out, but that's just my thought on the matter.
Your coral has a plating growth form with visible coenosteum ridges, running perpendicular to the edges of the colony. This is just a guess, but I would say that your coral could be a M. foliosa.
