Yes, I know this topic is old and I may be opening a second can of worms here
I was making a summary of the whole discussion for a Dutch forum I am admin for, and when writing the post some questions came up on my end. Here goes.
Recently, several species were 'moved' from Pseudotropheus to other genera. This is expected and not new. Other species were moved previously, species such as P. zebra, P. greshakei, and several others from the Zebra complex were moved from the melting pot that Pseudotropheus was (and still is, in my opinion) to the new Maylandia/Metriaclima genus - note that I am not venting my personal opinion here
I assume that more species will probably move at some point in time.
However, some of the species that got a new name, were renamed into Metriaclima. Species that were never part of the Zebra complex (as far as I know). Several species from the P. elongatus complex (Ad Konings) and the Pseudotropheus sp "kingsizei" (now Metriaclima pulpican as per Tawil, 2002). I think that the species from the Elongatus complex have not been fully described yet, so the problem may be less of an issue there?
Now, as Metriaclima is not completely recognized as valid, where does this leave these fish? Is Metriaclima pulpican invalid as a name?
Also, I have tried to find the article from Tawil where this change was published, but I am not sure where to look, so I don't have it handy, for which I apologize. If it is available on the net, I would be grateful if someone can send me a link.
By no means do I want to re-start the discussion, just looking for some answers out of interest in this hobby!
