Similar to some sphaeriids but differs in anatomy and hinge features.
This species is currently in the process of being described.
A freshwater swamp in the Lake Eyre basin spring complex, South Australia.
This species is only known from this locality and is believed to be threatened.
It can be easily confused with members of the Sphaeriidae but is most readily distinguished by the ligament which is housed in a pit below the posterior part of the hinge. In sphaeriids, the ligament is in a pit on the outer edge of the posterior hinge plate.
