Ehr well... If 3rd gen raths are supspecies of 1st gen ones, how can coloured/metal versions be another subs? Because they are based on the original Rath:

Rath species---Old world rath Coloured/metal sub ---New world rath Coloured/metal sub (they are based on New world rath, so they aren't the old world ones)

that doesn't make sense at all. I think that azure/pink and silver/gold are more aged versions
