General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~17mm long. Notice the side spines one the pronotum are very much reduced compared with A. varicornis.
It's surprisingly difficult to see, but the leading edges of the pronotum also have small spines/teeth (this occurs on both Alcaeus species we have depicted here). Note though the edges of the abdomen seem less serated compared to most pentatomids, looking almost smooth edged.
We have found 3 adults in Oct, Dec & Feb. We also found 3, what we think are nymphs, in May & June.
