Re: Maps needed to collect in Mexico.

Hi all,
regarding the maps, there is a good tool out from a Mexican government agency (INEGI): http://gaia.inegi.org.mx/mdm5/viewer.html

Re: Microgeophagus Frey, 1957, is a valid genus

Hi Ingo, I am not sure how to interpret your sarcasm, but as I stated before I do not agree with this kind of interpretation of Kullander's contribution. As for your "fooling" comment, I can only cite Konrad Lorenz: "It is a good morning exercise for a research scientist to discard a pet hypothesis ...

Re: Microgeophagus Frey, 1957, is a valid genus

Hi Juan and all, I was aware of Sven arguments about Mikrogeophagus because of the CICHLID-L where if I remember correctly Martin Geerts exposed them and Sven crowned them with the finding of Mikrogeophagus (Martin advocated Microgeophagus ), which appeared to me that he made in the research of the ...

Re: Microgeophagus Frey, 1957, is a valid genus

Hi all, I just worked through Kullander's account and I have to say he makes a solid, well-argued case for Mikrogeophagus. Particularly, I think his translations and interpretations of German texts are spot on. Also, in general, I do agree with the major problem he is highlighting. Scientific inquir...

Re: amatitlania id?

I would say they are A. nigrofasciata in the strict sense. I presume you mean in the broad sense;) Without collection information (or detailed phenotypic measurements) you won't be able to get a good ID. Considering the coloration of the male though, I feel somewhat comfortable in guessing that thi...

Re: Why? Experts are so Wrong!

Hi all, while I agree with most of the things that have been said in terms of explaining the reasons of why scientific names change, I'd like to offer a slightly different perspective that might be insightful. While it is true that naming species is subject to rules and regulations, I think it is im...

Re: Two New Australoheros Species

At a specific locality almost all modern 'species concepts' (there are more than two dozen serious concepts published) would recognize the same number of species. And all modern species concepts claimed to detect 'natural' entities as species. I am convinced that the so called 'Biological Species C...

Re: Two New Australoheros Species

That is the crux of the biological species concept, which defines a species as members of populations that actually or potentially interbreed in nature. You cannot adequately test this premise in allopatric populations. Hence, the use of other species concepts in taxonomy. Nonetheless, this species ...

Would anyone care to comment on the fact that there are many examples of two nearly identical looking cichlid species which are clearly shown be two distinct species? Many cichlids in Lake Malawi and Lake Tanganyika have such species in a multiplicity of examples. What holds true for one group does...

All I am saying is that Piotr's fish look like the C. myrnae I brought back in 2002 and the ones I currently have. Actually, sometimes I am bluffed by the similarity of the species with C. nanolut...
