Does anyone know of any other sources for the Lamia in D&D? Right now we have Pathfinder as one secondary source, but if there are any others please let me know.
There doesn't seem to be much information beyond which Monster Manuals it was in. If there's no other info available, perhaps the info could be moved to the "lamia in popular culture" article.
Wow, a lot of people armchair quarterbacking on how these Wikipedia articles should be structured. BOZ, I hope you're not operating on a vox populi, vox dei model, since you're the one actually constructing and managing these articles.
Anyway, Pathfinder has some additional lamia material in some of its early adventure path releases.
Pathfinder #2: The Skinsaw Murders has stats for the lamia matriarch (see also here). Pathfinder #6: Spires of Xin-Shalast has stats for the kuchrima lamia, harridan lamia, and the artificially-created hungerer lamia (these are the other forms of lamia hinted at in the Pathfinder Bestiary).
Pathfinder #6 also talks about the lamyros (the collective name for lamia-kin), as well as their society and religion.
There's a lamia that features pretty prominently in the Ruins of Andril adventure from Dragon Magazine back in the day - can't remember the issue number off-hand, though.
