General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~10mm long Female. Males in this genus have very large pectinate antennae.
What a strange looking beetle! It's elytra are semi-transparent making it look more like a sawfly.
The elytra are also very pointed, covering a much smaller area of the body than most beetles. There are few beetles where the hind wings are so visible.
