This one must have been lying on the shelf for a while. I was shocked to read that there were nine new Australoheros species to be described by Ottoni & Costa (in preparation), until I found out those had already been published in 2008!

[cichla]

Yeah, thats very true. However, I have no doubts that more new species will be appear soon.

At least it appears to be a species not only distinguishable for its authors (in contrast to the nine species named by Ottoni & Costa)! However, once again a comparision with an old taxon from the same area (Heros acaroides Hensel, 1870 from near Porto Alegre) is missing.

Dear Rico, Dear all,
according to Rican & Kullander (2008) the taxon Heros acaroides Hensel, 1870 is a synonym of Australoheros facetus. But there map (cf. Fig 1 in Rican & Kullander 2008) of the collecting localities of the facetus group is not congruent with this statement, because there is no locality of their facetus in the area of the type locality of Heros acaroides. Hensel (1870) distinguished his acaroides from Heros autochthon (a synonym of facetus) by a higher number of cheek scale rows (4-5 in acaroides versus usually 3 in facetus). This is why I think Heros acaroides Hensel, 1870 is not a synonym of facetus. A redescription is on the way and will be published soon.

Dear Rico,
Why do you think that the nine species ''named'' by Ottoni & Costa are only distinguishable by the authors? There is a clear diagnosis for every single species taxon.

The reason for thinking so I have given elsewhere in this forum:

As far as I understood correctly, the taxa Heros acaroides and H. autochton were only tentatively considered synonyms of A. facetus for the studies of Rican & Kullander are focused on the species of the Uruguay and Paraná drainages.
