The Silurian-Devonian lissatrypid genera Lissatrypa, Tyrothyris and Lissatrypoidea are shown to be congeneric, and junior synonyms of Australina Clarke, 1913; the tiny naviculate Nanospira is treated as a subgenus. Meifodia differs in the shape of the ventral median platform and the orientation of the spiraIia. Gracianella lissumbra differs only in lacking inner hinge plates, and (contra Johnson and Boucot, 1972) is considered most unlikely to be either ancestral to the Carinatininae, or closely related to Dnestrina, which is an anoplotheciid.
