Gangchengia subcylindrica n. gen. n. sp., is described from the Changhia Formation (Cambrian, Drumian), central Shandong, North China. The cranidium and pygidium of the genus were predominantly found from the same stratigraphic horizon within the Liopeishania lubrica Zone of the upper Changhia Formation. The new genus is diagnosed by its subquadrate cranidium, broad convex subcylindrical glabella, long palpebral lobe, wide downwardly sloping preglabellar field, and narrow convex anterior border. It is also characterised by a pygidium with seven pairs of pygidial marginal spines, of which the first and sixth pairs are longer, the seventh pair is shorter.
