New species: Vieja coatlicue :-)

Post by DRE »

Vieja coatlicue
(Actinopterygii: Cichlidae)
from River Coatzacoalcos, Mexico.

Del Moral-Flores, L.F., López-Segovia, E., Hernández-Arellano, T. (2018)

http://www.redalyc.org/jatsRepo/498/498 ... index.html

A new species of Central American cichlid is described, Vieja coatlicue sp. nov., from the Coatzacoalcos river basin (Oaxaca-Veracruz), Isthmus of Tehuantepec, Mexico. The species is easily distinguishable from its closest congener (V. zonata) with whom it was mistaken, for displaying the following characteristics: elongated body, posterior dorsal fin origin to the opercular rim, separation between the apex of the pelvic fins and the anus. A set characters that typify the species: spines and dorsal rays, generally XVII to XVIII, 10 to 12; anal fin VI, 7 to 9; pectoral fin, I,14 or 15; total gill rakers in the first branchial cleft 8-11; total vertebrae 30-31.

Actually the name is not valid right now. The current publication doesn’t fullfill the regulations of the code.
Nevertheless, I think it is the ‘species’ which is known as “sp. ‘Coatzacoalcos‘ “.
I would like to read opinions by experts of these fishes.

I don't think the article is published, since the magazine does not have ISSN that I can see. Also, I noticed there is no ZooBank registration. The species refers to what was previously known as Vieja sp. 'coatzacoalcos'. The type locality was set at a small tributaire of the Uxpanapa river at the town "El 11". I have read the paper although not in detail, but I notice that the diagnosis is flawned, also there are some contradictions of the diagnosis with the description. I think that this species may not obtain acceptance since the diagnosis may not stand, I will make a detailed analysis as soon as the paper is officially published.

Thank you, Philippe, for the update.

The short life of a cichlid species taxon,… !?

That it happens that species taxa shortly after their description are recognized as synonyms by competing authors is often conducted by emotional-driven work. So, it would be good to read a work by independent researchers.

It is probably good that there is such competition and the synonymy declaration was made quickly, or we would be stuck with countless names for the same species, with the confusion and waste of resources they cause. Perhaps this may encourage people to be more careful when describing a new taxon, knowing it will be scrutinized. Of course I am supposing here that the paper prove to has merits, as I am biased by my opinion even before and after reading the evidence presented

So sp. ‘Coatzacoalcos‘ is now synonym with zonata?
