Yes, from what I understand both Vieja and Cichlasoma are 2 very broad, generalized genera with countless "oddball" species falling under them, long overdue for revision, such was the case with the ratsnake genus "Elaphe" which included not only North and South American species, but Asian species as well. On a superficial level they resembled each other but anatomically and genetically were very different snakes with about the only thing shared in common was the name "ratsnake" and a forked tongue lol.
Cichlasoma probably more so than Vieja even, with entries like the Port cichlid (Cichlasoma portalgrense) and the Mayan cichlid (Cichlasoma uropthalmus). IDK about you guys, but I have a hard time seeing why these 2 should be in the same genus and what they actually share in common genetically or even anatomically.....but again, looking back Jack Dempsey was at one point classed in Cichlasoma, then moved to Archocentrus before finally being given it's own gena, Rocia.
Ironically, I tend to try and stay away from common names since the greek/latin nomenclature is a language every scientist speaks regardless of race, culture or dialect, but it certainly doesn't seem to be working out that way for the moment, does it?
2 things
1.) When you say Synspilum and melanuras, are you referencing them as species or genus?
2.) Are you stating that the Quetzal cichld and the Red-Headed cichlid are in fact the same fish? Even just by looking at them you can visually see they are different, don't you agree?

I think synspilum and melanurus are two different species or at least different colour variations.
Many of the ex-vieja are getting reclassified . Paranetroplus Synspilus seems to be the valid
name of the fish. Vieja argentea has also been reclassified as maskaheros argentea

The scientific name of a cichlid (or any other organism) is all about when it was described, morphological data, and lately DNA.
According to the latest studies melanurus and synspilla share the exact same DNA, so are the same fish (albeit different color, or location morphs).
Because the cichlid was first scientifically described in 1862, that species name takes precedence, Heros melanurus.
But genus names are in flux because DNA data may place what was once to to be in one genus, in another. Paratheraps is recent, 1989, and Vieja 1991, and Paraneetroplus 2010. So all the fish you describe are the same. Whether you think one appears to be more Amphilophus like, get a hump, or is aggressive, is really not relevant. Its all about scientific data. And scientific data is in flux as new developments come to light.
