Genus Onychodictyon Hou, Ramsköld, and Bergström, 1991

Type species: Onychodictyon ferox Hou, Ramsköld, and Bergström, 1991 (from Maotianshan , Chengjiang, Lower Cambrian) .

Emended diagnosis.—A robust lobopod, subcylindrical in outline, consisting of a “head” and an elongate trunk. The trunk with 10 segments, each segment possessing a pair of dorsal round plates and lobe−like appendages on the ventrolateral surface.

Remarks.—The genus Onychodictyon was first described by Hou et al. (1991) from Chengjiang. Our materials provide new information, indicating different species or sexual dimorphs that differ with respect to the presence or absence of “antennae”. Accordingly, the generic diagnosis is revised herein.
