Furcohaptor
Members of the genus "Furcohaptor" have a haptor with atypical structure ( two long haptoral arms , one pair of typical anchors , one pair of rod-shaped hooks , five pairs of typical-shaped marginal hooks , and one pair of marginal hooks which are reduced in size ) and the genus was originally placed in the family Ancyrocephalidae , but a study based on morphology and molecules demonstrated in 2017 that it was a member of the Diplectanidae .
