Introduction
Poulsen (1965) described Archasterope dentata, but did not attempt a generic diagnosis due to limited material. Kornicker (1993) provided a diagnosis which he later emended (in Kornicker and Poore 1996), noting a well developed d-seta, mandible e seta, s-seta with configuration 1+6, and no ridge on the inner posterior edge of the valve. There are 13 species. Five of these were previously in the genus Empoulsenia Kornicker 1975, synonymized with Archasterope by Kornicker (in Kornicker and Poore 1996). The appendages of the type specimen A. dentata are lost and it is not possible to verify whether the d-seta was a spine or a filament; other species in the genus have a filament.
