A species of the trilobiteDalmanitina (Dalmanitina) from Australia

Abstract

A distinctive new species, referable to Dalmanitina (Dalmanitina), is described from probable Ashgillian rocks in Victoria (Australia). This is the first described species of the subgenus from the southern hemisphere. It is shown that the Zeliszkellinae, to which members of this group have been assigned, contains forms with two basically different thoracic types and it is suggested that these should be given greater weight than in existing classifications.
