Esox cisalpinus & Esox flaviae same Species?

[Eternal Angler]

So originally I thought Esox cisalpinus and Esox flaviae were same Esox Species, but according to some websites, they are the same thing, Esox flaviae is a junior synonym and was a later name they used. I do think Esox flaviae suits the name better...

Esox cisalpinus is the scientific name for the southern pike, a freshwater fish native to central and northern Italy. Two research groups independently described the fish as a new species in 2011. Bianco & Delmastro's description was published first, and their name is the one that is accepted. Lucentini et al.'s description of Esox flaviae was published later and is considered a junior synonym.

But if you look at the pattern's closely, Etorre's southern pike listed as Esox flaviae looks a lot different than the other Gentleman's southern pike listed down below.

Maybe it's just how some tiger musky don't always look the same... Here's a typical tiger musky...

Then here's a tiger musky caught from Robbie and Lee that's completely different design than any tiger musky I've ever seen.
