In Reply to: Could this be D.c. orizabensis?..or rubidus... posted by regalringneck on February 17, 2003 at 14:10:39:
My female and 1 male are very white anteriorly then fade to slate gray...The "red tail" is a misnomer...You can see it in natural light, but it's more of a fine color change to a dull mahogony color from slate black.. I think "white throated Indigo" would be a better name or something more catchy
:Im liking it for a rubidus too, partic. w/ white anterior ventrals, whereas I would expect oriz. (if it really exists) ought to have the yellow ventrals of erebenus & melanurus...
:When I get down to Puerta Vallarta this June, I'll try & get .jpgs of a proper sample :)
::Did I not post my thoughts on this snake under the Mexican Drymarchon posts last month?
::Actually, you did, I just wasn't paying attention to ssp at that moment! And you suggested it could be orizabensis as well. My bad!
::For reference the snake was found in the low foothills. It would be lower down than snakes from Orizaba (depending where in "Orizaba" the specimens were actually taken), but not down as far as the coastal plain. I did see another all black DOR cribo (at high speed) further east towards Minatitlan as well.
::Just looking at the snake and thinking back to my encounters with a rubidus in Sinaloa, I suspect that orizabensis could just be an extension of the population of rubidus that has come across the isthmus through the foothills there (as other pacific coast species do) and run into melanurus when it hit the coast. Just a biogeographical hypothesis, for what it's worth.
