General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
About 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 about 5mm long. So really the antennae are about 7mm, with 5mm of filament nearly doubling their length. The filaments vary in length, with the middle being the longest at about 7mm, and both edges being ~5mm.
As with many longhorns, the eyes are heavily indented and wrap around the antennae base.
