General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~15mm long with very long thin wide filaments on the antennae.
It's difficult to determine how long the antennae are. Superficially they are a bit over 12mm long. However, the end segment has 2 filaments, of ~5mm long. So really the antennae are ~7mm, with 5mm of filament nearly doubling their length. The filaments vary in length, with the middle being the longest at ~7mm, and both edges being ~5mm.
As with many longhorns, the eyes are heavily indented and wrap around the antennae base.
