>>Glands I'm OK with, I just thought they were not rear fanged.
Accordign to Broadley, the maxillary teeth of Philothamnus are either all of approx. equal size, or the posterior teeth slightly larger than the anterior.
>>Thamnophis have the glands but not enlarged rear teeth, correct? I thought philothamnus were like that.
There is every possible continuum between no differentiated teeth at all to greatly enlarged and deeply grooved rear fangs, a la Dispholidus. Shoehorning colubrids into "rear-fangs" and "non-rear-fangs" is a pointless exercise. Moreover, some species with teeth that are only marginally differentiated have been known to inflict symptomatic bites - that includes Thamnophis, by the way, there have been several cases of swollen hands after bites.
Be that as it may, I have never heard of symptomatic Philothamnus bites, so I wouldn't worry about them unduly. As with all colubrids, it would be wise to avoid long, chewing bites, just in case.
Cheers,
