Legend-handling in mplot3d is no different from how it is done for 2D
plots. I don't know exactly how to do your particular example, but it would
likely involve passing legend() a list of Patch objects that represent the
markers you made, along with names.
Maybe these examples might be useful?

This one in particular might be very relevant:

I hope that helps!
