Re: 5 New Metriaclima Species

We started this thread from questions why the name Metriaclima was still being published as it was so obvious for all others it should be Maylandia. I explained my point of view about the invalidity of that name. I’m not going on a crusade to get either name accepted because very simply, and as ment...

Re: 5 New Metriaclima Species

The debate over whether the French phrase should be translated as "should" or "must" is a specious argument. The real discussion is about Mr. Konings' interpretation of the word "should" as having some strange ambiguity to it. I first looked in a thesaurus; should and must are listed as synonyms to...

Re: 5 New Metriaclima Species

As everybody seems to be paying attention again, what about my original question? :) On another note: in the article, several "black dorsal" varieties are now renamed as M. lundoense or M. nigrodorsalis. Does anyone know if M. sp "black dorsal" actually represents a group of fish, iE, are these var...

Re: 5 New Metriaclima Species

There are some who believe that the 'description' of Maylandia fulfill the rules, and others who think it is a nomen nudum. Dear Ingo, The description of a species/genus is not valid because others say so (Condé & Géry (1999), Bill Eschmeyer (website)), it is also not invalid because I say so. A de...

Re: 5 New Metriaclima Species

So others say that the diagnosis is made for the zebra group, not for Maylandia. It is clear in the text that greshakei and "zebra group" share the same caracters and belong to the same "group/sub-genus" which is confirmed by the next sentence : "we suggest that the zebra complex must be included i...

Re: 5 New Metriaclima Species

Hi Ad The problem is that, in the beginning of the story, you, and others, didn't understand really the french text an believe that there was no diganosis. This is not true. The diagnosis is valid and the priority rule must be accepted. Philippe Not only in the beginning, apparently we still don't ...

Re: 5 New Metriaclima Species

Re: Interochromis loocki ?

So you up Interochromis loockii and Petrochromis orthognathus in synonymy, if I understand well? Benoit, I. loocki and P. orthognathus are two different species. Although both are found in the sediment-rich areas of intermediate habitats, in the northern part of the lake it seems that I. loocki occ...

Re: Interochromis loocki ?

Maybe i've got something to add to this story. I've bought a group of Petrochromis orthognathus sp. Tricolor from Zambia (Chimba). One specimen, a female died, so I did a teeth check. If I follow Ad's 'classic' identification method I come to the conclusion that this specific animal is not a Petroc...

Re: Some news on Plankton-eater M'buna

Hi Nick, I think your photos show C. zebroides that have been in the aquarium for some time. The large size, more common for C. afra, is probably because they have been eating well for some time. Most C. afra have a very dark body because the vertical bars blend together leaving very little blue but...

Re: Maylandia or Metriaclima (rebound)

Now, as Metriaclima is not completely recognized as valid, where does this leave these fish? Is Metriaclima pulpican invalid as a name? Hi Serge, The Code for zoological nomenclature leaves no room for "not completely valid", it is either valid (available name) or invalid (nomen nudum). For what Me...

Re: Wildcichids discover new Aulonocara

Hi Esben, thank you very much for posting the photos of the new Aulonocara. It looks new to me. Perhaps closely related to the Aul. sp. 'blue orange' of George Turner's book. In one of the photos there is, what it looks like, a M. zebra. I have never seen algae browsers that deep. Could you ask Cars...

Re: Interochromis loocki ?

The issue of the bicuspid teeth does not really bother me knowing how plastic, variable or fast changing certain ecological traits are. Hi Adrian, the morphology of teeth (or anything) is not an ecological trait; and in my opinion ecological traits are much less variable than the morphology or colo...

Re: Interochromis loocki ?

Hi Adrian, I think there are a few problems regarding your ID of the "orthognathus tricolor" being I. loocki. The tricolor does feed like a Petrochromis and is part of at least three species that have been grouped around P. orthognathus . The type of I. loocki (photo attached) does indeed resemble t...

Hi Malawinut,

there are no naturally occurring OB morphs of any Cynotilapia. So the ones you are referring to, if they are indeed Cynotilapia, must be a man made hybrid of some sort. Enjoy your cichlids, Ad
