The oryctocephalid trilobites from the traditional ‘lower-middle Cambrian’ represent key tools for international correlation. The trilobite zones in South China around the Cambrian Series 2-Miaolingian are made using oryctocephalids. One of the trilobite zones suggested is based on Protoryctocephalus arcticus. Protoryctocephalus from the Balang area in South China was described as Protoryctocephalus wuxunensis, also from the Cambrian Series 2 of South China. However, Protoryctocephalus from Balang shows different morphological features such as different glabellar shape, presence of a transglabellar S1 and more segments in the trunk. These features match with Protoryctocephalus arcticus from the Cambrian Series 2 of Greenland.
