Welcome to Ratsnake Zone

Welcome to Ratsnake Zone, I'm so pleased that your search, brought you here. The purpose of this website is two fold, firstly it is a place where I can show case my Ratsnakes and offer their offspring for sale. Secondly as an information portal, via articles.
I am a private breeder based in the UK, with a keen interest in all Ratsnakes, especially Elaphe dione, of which I keep and breed several localities and morphs.
If your first language isn't English, translations are available at the top of the page, by clicking on the respective flags.
Thank you for visiting and I hope you enjoy your visits - Sue x

New species of Elaphe

Phylogenetic Analyses Reveal a Unique Species of Elaphe (Serpentes, Colubridae) New to Science
Authors: LING et al.
Abstract The snakes comprising the monophyletic group referred to as ratsnakes are found throughout Asia, Europe and the New World. Recently, three snake samples likely belonging to the ratsnakes were collected in Zoige County, Sichuan Province, China. Species identity was difficult to delimit morphologically because the specimens were juveniles and partially damaged. Subsequently, a molecular phylogenetic approach was used. Portions of three mitochondrial genes (cyt b, ND4 and 12S rRNA) were sequenced and analyzed. The results showed that they were sister to the genus Elaphe. Very little genetic variation was found among the three samples. The minimum genetic distances between these samples and those within Elaphe were greater than any currently recognized species within the genus. We conclude that this likely represents a new species within the genus Elaphe. Adult specimens and a morphologic description are needed for further study.
A new paper has been submitted for publication describing the species and should be published some time this year.
What we know so far is it will be in the genus Elaphe and specimens have been found in Zoige County, Sichuan Province, China.
I've talked to Frank Burbrink one of the authors and he describes the new species as a 'little beaut'.

Blue Beauty Scientific Name
|

Jul
2010
The Blue Beauty has been proved to be a distinct taxon and assigned the subspecies of Orthriophis taeniurus callicyanous
Named in honor of Trevor Smith (UK) who coined the name 'Blue Beauty' the scientific name is from the latin Kallos meaning 'Beauty' & kyaneous 'dark blue, cyan'.
There are two 'colour phases' of O.t. calllicyanous The Blue Beauty & The yellow Beauty
Also there is a new subspecies from Myanmar & Thailand, named after Notker Helfenbeger (Switzerland). Orthriophis taeniurus helfenbergeri.
The paper is in German with an English Summary, is 24 pages long exc. references and has many photos to illustrate the different subspecies. Distribution maps for the two new subspecies and new locality details for mocquardi & yunnanensis. Apart from discussions on the variability in the Orthriophis taeniurus complex, distribution and natural history data is provided. A key to identification and table of scale counts
