Korniushin (2000) noted that the "Shell outline, position of umbo and hinge details are subject to individual variation...............is similar to the form of S. tasmanicum distributed in the upper Murray catchment but differs from it in its solid shell and strong hinge.These characters were also evident in the population from Attunga State forest living in sympatry with M. tasmanicum". S. (M,) quirindi is distinguished from M. tatiarae by its small, elongate and inflated shell as well as by its dense shell pores (Korniushin, 2000).
