General Species Information:
Found in the Adelaide Hills and possibly elsewhere
~11mm long, which is reasonably small.
Primarily black top & bottom, with a beige to pink rim around the body. The black sometimes protrudes to the outside edge. Here they don't and used to be considered different sub-species where they did.
While they generally have 4 antennae segments, you'll notice one here only has 3 on one and 4 on the other. Normally you'd consider this a loss of one tip, but the remaining tip seems longer and rounded. Possibly a malformed antenna rather than a broken one.
At each antenna base, they have a large hooked spine protruding forward. This is called the "antennophore".
An uncommon find. We found two one year in Jan & Feb.
