The genus and species were first described in 1986.[2] Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the stapeliad genus Hoodia. Marginally more distantly related is a sister branch of related genera including Larryleachia, Richtersveldia and Notechidnopsis.[3]
