Description
Genus Austrotindaria Fleming, 1948
Type species. Austrotindaria wrighti Fleming 1948; Holocene, Quaternary; Southland, New Zealand.
Diagnosis. Delicate almost smooth shell, with weak concentric sculpture. A short, edentulous gap between the posterior and anterior hinge plates. No pallial sinus and without rostrum.
Remarks. The Neilonellidae comprises three valid genera: Neilonella, Austrotindaria and Pseudoneilonella (La Perna 2007). The convex shape of the posterior margin and the presence of an opisthodetic ligament in our specimens indicate better agreement with Austrotindaria than Neilonella (Di Geronimo & La Perna 1997; La Perna 2007). Austrotindaria differs from Neilonella and Pseudoneilonella by having a delicate, almost smooth shell rather than a sturdy, sculptured shell, and by having a small elongate pit below the posterior and anterior teeth (La Perna 2007). This genus is currently known from the Miocene to Recent (La Perna 2007; Coan & Valentich-Scott 2012), and the specimens identified in his study extend the range of the genus to the beginning of the Triassic.
