Crenicichla sp. Iquazu big lips (or sp. botox) has a name.

[DRE]

Also another species is described.
Crenicichla tapii.

Crenicichla sp. Iquazu big lips (or sp. botox) -> Crenicichla tuca.

Finally some discussion on mixed material in the description of C. yaha resulting that they should now be called C. tesay and a new description is needed for the subset of material in the yaha description. This is very unclear for me and I would need some real hand holding to get it.

Lubomír Piálek, Klára Dragová, Jorge Casciotta, Adriana Almirón, and Oldřich Říčan. 2015. Description of two new species of Crenicichla (Teleostei: Cichlidae) from the lower Iguazú River with a taxonomic reappraisal of C. iguassuensis, C. tesay and C. yaha. Historia Natural 5: 5-27.

Thanks! Is the description public domain? Do you know where to find it?

[DRE]

In crenicichla Facebook group. Not sure if it is public domain, but I have the paper.

Is there a link to the paper?

I am so glad that C. tuka was not given the corny name of C. "botox" as its formal name.

Hehe

What about C. oliverlucanusii. That would had been a nice and deserved name

[Mark Smith]

Of course, that would have been much better. He does deserve to have more than one species named after him for all the interesting/rare species he has brought into the hobby.

Can someone explain what happens with C. yaha?

[Mark Smith]

When looking at the color photos of live C. iguassuensis and C. tuka in this paper, it is hard to imagine how the authors of the 2001 paper thought that C. tuka was a polymorphic variant of C. iguassuensis. The mouth shape is completely different, among others.
