new long-tailed rattlesnake

[TJ&ACP]

In a surge for an updated list of all Crotalus species that I have not yet found, I stumbled onto this article of a new long-tailed rattlesnake that was not listed on any of the lists I have seen. It is not even listed on the Clinical Toxinology Resources web-site
Here is a link to the article:

I had no idea some of these main species had so many sub-species. How old is this list? One obvious thing I picked up is that Crotalus durissus vegrandis is no longer a sub-species and has been elevated to full species status. Its now just Crotalus vegrandis.

[LizardLover]

So much species.

Hi Wade

This list I am trying to compile, I found +/- 4 lists and they are not one that is that same as the other. The Clinical Toxinology Resources web-sitehttp://www.toxinology.com/fusebox.cfm?fuseaction=main.snakes.search
still got it as C.d. vegrandis.

Crotalus durissus durissus and Crotalus durissus maricelae are not listed under C. durissus and I could not find there new classification.

I have found that Crotalus cerberus use to be Crotalus oreganus cerberus
and
Crotalus ravus use to be Sistrurus ravus

Sorry for the late comment. I've not been online in about a month. Your list looks pretty complete, but I think Wade's right about vegrandis.

Crotalus cerberus was indeed considered a subspecies of oreganus for a while. It was also considered a subspecies of viridis for a time, as well. Speaking of viridis, though, I don't believe that nuntius is still a valid subspecies. While the Hopi rattlesnake is much smaller than the Green Prairie rattlesnake, I think they've been lumped together. Personally, I think that oreganus and viridis are so similar that they should be combined into one complex, with the Hopi being a valid subspecies.

If the rumors I've heard are true, mitchelli may have a new subspecies soon, as well.

Thanks Thomas I was hoping for a replay from you, as this far all lists that I could find do not have the resent changes and that make them out dated. It would be appreciated if you can update the list as soon as there is a change as you mentioned,
Regards TJ

[croteseeker]

Well, TJ, I was rereading this thread and I thought I'd do as you asked and keep you updated on one of the more recent changes in this list. Crotalus molossus molossus has been split into not only different subspecies, but different species, as well. The Eastern species is now known as C. Ornatus. This is an older division that has been reinstated in order to more clearly mark the lineage of these respective species. C. ornatus - those blacktails East of the Sierra Madre Occidental and the Southern Rockies - is, once again, thought to have descended from C. totonacus, whereas C. molossus is still heavily influenced by C. basiliscus (see C. m. nigrescens) and regularly hybridizes with it's Mexican cousin.

Speaking of hybrids, I had a discussion with someone on a different forum regarding natural hybrids in the crote world. I'll post some photos in a different thread and see if anyone can guess the species.

[TJ&ACP]

Thank you for the update; I did see that thread, which will be an interesting post.

[TJ&ACP]

I have found yet another site that was updated Jun13, there are now 37 species (Crotalus) and 2 (Sistrurus).

This site gives the legacy of names as well. For example:

Caudisona lucifer var. cerberus COUES 1875
Crotalus viridis cerberus — KLAUBER 1949
Crotalus viridis cerberus — JONES et al. 1981
Crotalus viridis cerberus — STEBBINS 1985: 231
Crotalus viridis cerberus — CROTHER 2000: 60
Crotalus oreganus cerberus — ASHTON et al. 2001
Crotalus viridis cerberus — POOK et al. 2002
Crotalus oreganus cerberus — CAMPBELL & LAMAR 2004
Crotalus cerberus — DOUGLAS et a. 2002
Crotalus cerberus — BEAMAN & HAYES 2008
Crotalus cerberus — HOSER 2009
Crotalus cerberus — WALLACH et al. 2014: 189
