Material. Four specimens ( Sa elements ) from the Tabita Formation at Mount Arrowsmith, and an additional specimen (Sa) from the unnamed dolomitic limestone unit at Koonenberry Gap.
Remarks. This species is rare in our collections, only the symmetrical Sa element being recovered. It has a proclined cusp, an anterolateral costa on each lateral side, and a thin posterior margin basally bearing a row of small, closely spaced denticles. The specimen illustrated from the Horn Valley Siltstone ( Cooper, 1981) is a weakly asymmetrical, acostate Sc element of the same species.
