The species was first described by Robert Broom in 1927 as a transitional species between early synapsids and later occurring therapsids.[2] While it was later suggested that the fossil material, a partial poorly preserved skull, was not diagnosable and that the species name is nomen vanum.[3] It was assigned to Varanopidae (subfamily Mesenosaurinae) in 2018.[4] The fossil is from the Permian of South Africa.
