Genera

The Luolishaniidae[5] or Luolishaniida[2][6] are a group of Cambrian lobopodians with anterior 5 or 6 pairs of setiferous lobopods.[1][3][2] Most luolishaniids also have posterior lobopods each with a hooked claws, and thorn-shaped sclerites arranged as three or more per trunk segment.[4][1][2] The type genus is based on Luolishania longicruris Hou and Chen, 1989, from the , South China.[5] They are presumed to have been benthic suspension or filter feeders.[4][1][3][2]

New specimens of the previously enigmatic Facivermis show that it was a sessile tube-dweller, and part of this group.[3]
