Thank you Mark Hura for identifying this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
1st Live Photo on-line:
We have recently discovered the enclosed head is not a diagnostic feature of Helea sp.
Notice how round this species is compared to the next (Helea waitei).
It's quite unusual as it's brown plus has a transparent "shell".
We're not sure if the "brown fluff" is just plain dirt, or possibly excreted by the beetle as camouflage. Another possibility is cobweb from a tiny spider
This specimen was 22mm long including the flanges of the Elytra (rear shield / wing covers) and Prothorax (front shell), 18mm just the head & body without the shell.
This specimen has 2 ridges starting at the front of the elytra stopping about 3/4's toward the rear, roughly where a 3rd middle ridge starts.
