I'm not sure why this took so long to post, because I wrote and
sent it about 9 hours previously. Oh well.
Here's why I'm less than sure of that id:
1) Your specimen appears quite gracile, while the photographed
specimens on the web appear fairly "stout" -- not gracile.
2) The reported maximum length is 75 cm; average specimen seems
to be 30-60 cm
3) Color and banding in snakes can be variable. Here, for
instance, is the US Armed Forces photo:
4) There is at least one other green snake in Sudan, Philothamnus
angolensis, growing to a maximum of 1.2 m, averaging around 1.
The photos I've found of this species appear more gracile.
5) Photo identifications are always tricky. In my own field of
botany, there are many, many plants that I refuse to even try to
id from a photo -- you just can't see what you need to see to
give a firm id.
