Pilumnoidea is a superfamily of crabs,[1][2] whose members were previously included in the Xanthoidea.[3] The three families are unified by the free articulation of all the segments of the male crab's abdomen and by the form of the gonopods.[2] The earliest fossils assigned to this group are of Eocene age.[4]


Pilumnidae is by far the largest of the three families, with 73 of the 78 genera:[2]

Pilumnidae Samouelle, 1819
Galenidae Alcock, 1898
Tanaocheleidae Ng & P. F. Clark, 2000
