Dear Venomland Members and Friends, Venomland is a little more than 6 years old now and by far the biggest Hot Snake community on the Planet! We want to thank all of you who made Venomland the leading Board. We are also very thankful to our Moderators and Admins for years of hard work. Now, it is time to move on. I have been thinking how to proceed and what to do with our beloved board as we reach a size, that we need to make drastic changes to secure the future of our community. As of now, Venomland is hosted by a free (well mostly free) hosting service. That was good for the first years but now we need to find a new way to run our forum. I have spend hundreds of Dollars over the years to keep Venomland up and running, and i have done so with pleasure. Now, we need your help! We need to come up with several thousand dollars for our Venomland 2.0 project, which i frankly cant pay for any longer by myself. So Venomland is asking his Friends and Members for the first time for their financial Support. Please help to keep Venomland alive, and let us move on to a new, better Portal in the Future! Every Dollar is helping us a great deal. I know, its hard times for everyone, but please spare a few Dollar for our community. If you have only 10 Dollars to spare, we are grateful, if it is more, it would be awesome. We are planning to develop a very new Venomland, with real community functions, a forum like you are already loving it and a real (online) Hot Snake Magazin. Also, there will be download areas for scientific papers, Wallpapers and more. Again folks, we can only do that if you all help. Please send me a Private Message if you want to keep Venomland alive, i will provide you with the details on how to donate Money. For now, we can accept money from creditcards via skrill (please google it, its a free service - account-details will be forwarded to you) and paypal. All the best, and for a (hopefully) nice future of our Board. Mario

Never seen a Dendroaspis angusticeps with black coloration between it's scales.
Can you post a picture?
Is there a difference in form or size of the scales in your two specimens?

Peter

Yes, strange...are you sure it's a D.angusticeps?
I will be curious too to see a photo.
Thanks!

Well, i know that the green color can be very different in angusticeps - lighter or darker green - even a yellowish green is possible. Some specimens can have a few yellow or blue spots.
I've never heard of black between the scales in this species, but even if it isn't that prominent it would be interesting to see a picture.
If the size of the scales is the same we can at least exclude Dendroaspis viridis.

No problem at all, Mark!
Very beautyful Dendroaspis angusticeps.
My specimens do also have these interstitial skins which i would describe somehow as dark, but not that jet black as yours.
Really an outstanding specimen - unfortunately i cannot tell you if that's depending on locality and if yes which locality it could come from.

Peter

Thanks Peter but its not my snake. It's one I found on the Internet but answers the question as to whether they exist. I have seen one for sale in Hamm a few years ago. It was a very young specimen, less than one year old. If they were a locality form, we would probably have seen and identified them by now. I think perhaps they are just a colour anomaly. Just like the specimens with blue coloration that we see from time to time.
Regards. Mark.

No subspecies of angusticeps have been described so far.
I think this phenomenon belongs to the normal spectrum of variation in colour.
If you check google images you can find all nuances of interstitial skin colouring - from light grey or light brown to dark grey or brown or black - even dark blue.
It seems to me that these black skins are more common in dark green specimens, but that's a hypothesis which needs to be verified....
We have to consider ontogenetic colour changings too - one of my specimens has been sold as a dark green South African specimen as a juvenile/subadult and changed to a light yellow green as an adult. Unfortunately i dont have any older pictures.

Peter

Yes, but Broadley a Blaylock (2013!) have revised species Dendroaspis angusticeps and revalidated "new" species D. intermedius as D. angusticeps from central Mozambique and north. Results also supports morphology genetics (cf. Wüster). Dendroaspis angusticeps remains only in SA.

I do not think that serious taxonomical revisions will be published in books you mentioned.
So my question is: where has this revision, revalidation of an "old" or description of a new species or whatever been published under the rules of the code?

The name – intermedius - (Gunther, 1865) for the populations from East Africa was recently used by D. Broadley and R. Blaylock in their book about “The snakes of Zimbabwe and Botswana”(Chimaira, 2013). This “revalidation” is based on still unpublished results (although some results were already published in the form of abstract of some “conference”, but sorry I don´t know now where :-( of a revision (based mainly on molecular analysis + but plus morphology) of this group of green mambas, made by D. Broadley and W. Wuster and other co-workers. The results will surely be published, but I don´t know when...You must to ask the authors.

It is up to you whether you use the information in the mentioned book or will wait for “serious revision”...

This is what Johan Marais have to say about the topic.

Seems that the splitting up of the Boomslang and Green Mamba in the "Snakes of Zimbabwe and Botswana" by Broadley and Blaylock has some of you confused. let me deal with the Boomslang first: Thomas Eimermacher has been working on the genetics of Dispholidus and found significant differences between those from the Southern Cape, Western Cape and Eastern Cape as opposed to the populations elsewhere. Dr. Don Broadley, in his new book, decided to split them into the Cape Boomslang (Dispholidus typus typus) and the Common Boomslang (Dispholidus typus viridis). The species account in Don's book is the only reference to this split and there are no other recent publications on this subject. I guess it will be more clear once Thomas publishes his results. As for the Green Mamba it is a similar situation. According to Don the molecular data for Tanzanian specimens differed markedly from those from KwaZulu-Natal and he split the Green mamba (formerly Dendroaspis angusticeps) into two species - the Southern Green Mamba (Dendroaspis angusticeps) from KZN and the Eastern Green Mamba (Dendroaspis intermedius) from elsewhere further north. Again, these changes have not been published elsewhere. It appears that molecular data from specimens from Mozambique fit in between the two species so it will be interesting to see what the taxonomists are going to make of this in the near future.

I was recently made aware of this thread, and will thus add a few comments. Don Broadley and myself have been working on the systematics of dispholidine snakes for a number of years now. With regard to the genus Dispholidus, we have in fact found solid evidence of a phylogenetic structure that is going to lead to taxonomic revisions within the genus in the near future. The taxonomic revisions made by Broadley and Blaylock (2013) were their own, even though they were based on some of our data. However, our own taxonomic revisions are going to be based on a significantly larger, more complete data set, and are unlikely to be congruent with the changes proposed by Broadley and Blaylock (2013).
