What does FIDE stand for and what does the organisation represent?
I highly doubt you are talking about the Mexican Fideicomiso para el ahorro de la energía eléctrica (FIDE)
Other than that, that's my best guess...

Skeletal: Humerus, Femur
Well, actually you are missing more than a couple of systems... Although you may look funny with only those mentioned
