I'd personally go with 'Homo-', then whatever the species name of animal part is. Like Homo Rattus rattus for Reinegan(sp?). Although you may have to do quite a bit of research to find the exact species. Rattus rattus is just the common brown rat, but Reinigan could easily be based  off a different species. Ones based on non-animals may be a little harder, but I'm in favour of Homo Lupis for Blutbad (I consider them to be based on traditional werewolf instead of any particular species.)
