Hey are sure you have the latin right? Just wondering because I really wanted to see what one looked like but google and yahoo didn't come up with anything.
oh it's Pseustes poecilonotus, I opened a book.........you remember it's one of those things we used when we were kids!..LOl
Quote from The Completely Illustrated Atlas of Reptiles and Amphibians for the Terrarium (not to long of a name

) T.F.H.
"
Pseustes FITZINGER, 1843. Genus of the Colubridae, Colubrinae. Neotropics from Mexico to southern Brasil. 4 species. Among the largest Neotropical colubrids, togther with the Spilotes and Chironius. In outer forest zones. To more than 2.8 m. Strongly built. Usually dark brown, often with yellow bands. Diurnal and crepuscular semiaboreal snakes that feed preferentially on small mammals. When excited
Pseustes species inflate their throats and simultaneously vibrate their tails. Can be kept much as
Elaphe but in a well heated terrarium.
.
P. poecilonotus (Guenther, 1858). Mexico to the Amazon Basin.
.
P sulphureus (WAGLER, 1824). Amazon Basin to south-eastern Brasil."
Other species shown are Pseustes poecilonotus polylepis and Pseustes shropshirei.
The first is drawn but the second shows a sub adult a slate blue grey like a Japanese ratsnake color with moderate faint tan banding slightly darker on the back like sadle and fading down the sides. Banding looks to be more pronounced near the tail. Hope this helps! Those are very cool snakes and keep me in mind if you can breed them

Me likey! LOL TB.
