Musculium (Sphaerinova) tasmanicum queenslandicum (E. A. Smith, 1883)
"The form observed here is distinguished from typical M. tasmanicum mainly by it's peculiar shell outline and posteriorly shifted umbo. Some differences in anatomical characters are also notable: the northern form has weaker siphonal retractors and an elongate dorsal lobe of the nephridia" (Korniushin,2000).
