A Lamia is a half-woman/half serpent creature (which I at first mistook for a mermaid when I first saw it) which serves as the Kuriotate Arcane line in my modmod. The name is taken from a child-eating daemon in Greek mythology, but there is no indication that the Lamiae of Erebus are such wicked beings. I think that Kael intended to add them to the main mod, but never got around to it. It took a while for someone to make decent animations for them. The models themselves have been around as long as the Succubus. They are basically the same as Succubi from the waist up, except for the lack of wings and the presence of some clothing on the Mage and Archmage versions (the adept is still nude). I know I found the files in the FfH II Art Team Blog thread, but I can't seem to find the exact post. You could take them from my modmod (if you unpack Magister.fpk) instead if you wish.
