Australoheros perdi new species

[cichla]

Ottoni et al. (2011): Australoheros perdi, new species (Teleostei: Labroidei: Cichlidae) from the lacustrine region of the Doce River Valley, southeastern Brazil, with biological information. Vertebrate Zoology 61(1): 137-145.

Wow... another one? Who will be able to keep these things apart. Maybe they should just start numbering them.....

[dogofwar]

I assure you that all of these have different names

Another one and counting.

I do not find the document yet.

Rafael,
currently, only the print version is available. I guess, however, it will be ready for download soon.
Michi,
yeah, indeed a lot of Australoheros described during last decade.... and many new species on their way. Well, since it is most likely that Crenicichla and Apistogramma will be splitt soon, it might be that Australoheros will be one of the most speciose genus of SA cichlids.

This must be the longest name ever:

Australoheros perdi Ottoni, Lezama, Triques, Fragoso-Moura, Lucas & Barbosa, 2011

I wonder if we could just call it

Australoheros perdi Ottoni et al, 2011

What a shame that there is no color photo of a live specimen in this paper.

I was thinking the same about statistics.....

I have only just browsed through the paper, but already there is some great news! This species should be placed into a new genus.

As stated by Ottoni et al it has bars 6 and 7 interrupted in their dorsal parts. Bar 5 is thus continuous. This does not fit the diagnostic Australoheros character of (all) abdominal bars (bars anterior of bar 4, the one with the midlateral blotch) being interrupted. See also Rican & Kullander 2006 and their picture on page 6.

Further comments to follow in my Australoheros article.

Not only that... perdi has 25 vertebrae (versus 26 ore 27; as stated in the diagnose of Australoheros by Rican & Kullander, 2006)

What kind of statistics? Since the species is discriminate by non-overlapping character states, I think, in this case it wouldnt help much to decide whether there are significant differences or not. Nevertheless, I endorse that in cases of continuous data it is helpful to confirm the results by using an appropriate statistical method.

What a shame that there is no color photo of a live specimen in this paper.

The paper is written by taxonomists and ecologists. Those scientists dont care much about what aquarists wants. Since the taxon is not based on characters or character states of the ''Color in life'' there is no need to include such photos, at least from a scientific point of view. Anyhow, I agree that it would be nice to have a photo of a live specimen. However, I think, it wouldnt help much to determine the species.

Article 51.1.(ICZN) ''The name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable''. A more radical solution is discussed by Dubois (2008). He suggested that authors names should not cited after scientific nomina of taxa. So, no need to cite all authors. I think it is possible to use ''Ottoni et al.''

does anyone have a picture of this fish please?

[cichla]

?

I too cant find any picture on it...but thanks for the article, this is all very exciting.
