Liliaspis was, at various times, placed in the families Cyathaspididae, Poraspididae, and Anglaspididae. Currently, it is placed in Ariaspidae with Ariaspis, and Listraspis, and is considered to be closely related to the similar-looking Paraliliaspis. Anglaspis is considered the ancestor or sister-taxon of both L. philippovae and Paraliliaspis.
