Pseudoiulia
Pseudoiulia is a genus of Cambrian arthropod known from the Chengjiang Biota of Yunnan, China, containing the single species P. cambriensis. It is considered poorly known, but has been somewhat associated with other Chengjiang Biota fauna such as Dongshania folliformis and Pisinnocaris subconigera. In 2013, Pseudoiulia was suggested to be a member of the family Kootenichelidae, alongside Kootenichela and ''Worthenella.''
