In fact current phylogenies suggest that the presence of Duvenroy's is the ancestral condition in Colubrids. How that idea will hold up as phylogenies are expanded and the family Colubridae is broken up is hard to say.

However, the presence of Duvenroy's glands does not suggest at all that this species is opistoglyphous as there are other "colubrids" that can inflict potentially dangerous bites that do not have "rear-fanged" dentition. I believe Rhabdophis is an example of this.
