Thank you Agapakis Nikos for confirming and Grant Schiermeyer for helping with the id of this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Those we have found vary between 10 to 16 mm long. We've photographed 4 live specimens in March, April, June & July. We found the 5th, dead, specimen to highlight the hour-glass shape
We thought this was a Pill Bug (Armadillidium vulgare).
It's difficult to see here but the Telson (last posterior plate) has an hour-glass shape.
Grant spotted our mistake and also noted: "You can tell the families apart by the telson and the front of the head.
Armadillids will have an hourglass telson and Armadillidiids have a triangular or trapezoidal telson.
The front of an Armadillid head is usually one smooth line that may be broken in the center while an Armadillidiid will have a nose-like projection in the middle of the head."
