With all the Ancients resembling Hyurs, it's likely that every single other race was 'created' in some fashion. We even know how the Ixal came to be from the Fractal Continuum (and, now, that it was almost certainly Amon who did it.)

My guess is that Hydaelyn created the form of the Loporrits, but like everyone else they received souls from the Lifestream.
