General Species Information:
Found on Ellura (in the Murray Mallee), and elsewhere
About 18mm long. With the 3 specimens we caught in one night there seems to be some variation in the amount the abdomen protrudes past the elytra, but not overall length.
The spots on the thorax are made by hair, and so variations in colour, shape & quantity can be accounted for easily with age & wearing.
The vague patterns on the elytra may be due to transparency of the underlying body (but didn't manage to see it with elytra up to prove this). These patterns are quite variable.
Also note with longhorns that the antennae are often 2 dimensional. As such, some photo's of them appear thin/thread like. Others a thick heavy serrated appearance, where the antennae are at 90 deg. This is because the serrations are plate like and nearly invisible from the edge. As such, it's a good idea to get plenty of photo's of the antennae from different angles to get the correct shape of the segments.
