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.
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.

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.''
