Close to Cottaldia, from which it differs in having sparser tuberculation and in having more plates in which one or two elements in each triad are reduced to demiplates. Previously this taxon has been placed in the Pedinidae. However, when well preserved, the larger adoral tubercles are distinctly crenulate, as reported by Smith & Bengston (1991).
