Acanthobdellidea
Acanthobdellidea is an infraclass of primitive leeches; some authors place them in a separate subclass from the Hirudinea. However, the World Register of Marine Species places them within the Hirudinea, as a sister group to Euhirudinea, the true leeches. 

Species in the group include "Acanthobdella peledina", described by the German zoologist Adolph Eduard Grube in 1851, and "A. livanowi", described in 1966.
