Well - when I say that I mean they have now been named as one species in a published paper, as far as I know it now means that this is what they will be called from now on, but it takes a while for the general scientific community to accept any name/genus changes as someone might argue some other case (i.e. that they could all be called bricks)
One of my Prof's at uni is going through the process now - he and some colleagues have just re-classified all of the NZ Hebe's (plants) as Veronica's (its a long story!) and although it is now sort of official, it take a while for it to move down through the system till people actually start using the changed names, does that make sense??!
