Let's see, mostly from lack of inclusion into Violated Hero and the Monster Girl Encyclopedia:

Fallen/Dark Angels or Demon girls besdies the succubi and imps - in fact, I think this is very likely to create a new villain now that Illias and the angels are neutralized

Sheep, mouse, and bear girls

Giant/Oni/Ogre/Orc girls (or maybe another Goblin or a Dwarf)

Witches or fallen/possessed human girls

There is only one nekomata/cat girl, so there is room for variety there; same with minotauros/cow girls and centaur girls

Sea dragon/sea lamia girl

Griffin girl

Cyclops girl

Kaimataich(spelling?) - a bladed weasel thingy

Sahaugin
