I was reading an old book and it said the the Red Diamondback Rattlesnake(Crotalus ruber) is likely, in the future, to be changed to the new name of Crotalus exsul. Is this still a possibility?

Hi,
I have a couple of rubers and have not heard this. How old was the book that you read this in? I'm interested too so anyone who has this info, always appreciated.

Heres what the book says word for word: "What's a name? As species' relationships with eachother become better understood,name changes are inevitable. The red diamond rattlesnake is called Crotalus ruber at present but a name change, to Crotalus exsul, seems likely to take place soon."

Hmm, that's interesting. Never heard that before. I've already had my Crotalus Horridus Atricaudatus change to just plain Horridus Horridus so what's another change.

If it were changed to the species exsul, it would have to be a subspecies..probably ruber. There is already the nominate. Crotalus e. exsul is the Cedros Island diamond rattlesnake.

Ahh I'm a stickler for details and rather old fashioned. It is appropriately the Red Diamond Rattlesnake, not Red Diamondback, There is an Eastern and Western Diamondback but no Red, kinda like there is an Anaconda and a Yellow Anaconda but no Green Anaconda.
This is exactly why we have/use scientific names....uhh wait, No one knows which scientific name belongs to which snakes anymore.... gotta love Taxonomy!
Ah hell, why don't we just call 'em the Big rattler from Florida and the mean ones from Texas and the little ones in between.... :)

The old name for the Red Diamond Rattlesnake should be Crotalus exsul as it was first described and it has been shown that Crotalus exsul and Crotalus ruber are the same species. But, the ICZN accepted a proposal to retain the use of Crotalus ruber because Crotalus ruber is used much more and is better known.
Check out Wolfgang Wuster's site for more detailed info on that: "http://biology.bangor.ac.uk/~bss166/Updates/Crotalinae2000.htm"

Green anaconda is the common name for Eunectes murinus. There is also yellow anaconda, DeSchuann's Anaconda, and the recent Eunectes beniensis (not sure about its common name).
The scientific name is still Crotalus ruber. Crotalus exsul was found to be the same species but they are now 4 subspecies of ruber. Grismer was trying to get lorenzoensis classified as a seperate species. He split quite a few species in his Baja book.
The Chris Mattison book is good but be careful with taxonomy on some of the older books because things change so much. Vipera russelli is mentioned in that book, need I say more. Also, Chris Mattison's books are geared towards a less scientific audience so current scientific data isn't always used or completely accurate. You can find mistakes quite easily in books from Barnes and Noble. For example, I just skimmed through the book to prove my point and on page 246 it has a picture of Deinagkistrodon acutus labeled as Porthidium nasutum. No one caught it because it probably wasn't reviewed by other herpetologists. This happens all the time with these books, though they are still useful for just reading and I still like the book.
Just be careful,
Robert

When Eunectus marinus was described it was simply Anaconda. It is/was the pet trade that termed them "Green" Anacondas. The fact still remains that it is appropriately just "Anaconda"
