| Species: | Black-striped Shield Bug (Amphaces sp ES01)| This Photo: | 🔍S1, Male, dorsal🔎 | Thank you Danilo Lüdke for identifying this species for us General Species Information: Found on Ellura (in the Murray Mallee, SA) and elsewhere ~7.5mm long, Male. NB: it seems to have a parasite on it's wing, just a little round pale blob. While these are normally green, we have found this colour morph with Cuspicona before. Online they can even be brown, bordering on red. Danilo said "Gross probably skipped the Acanthosomatids on purpose... this group is a terrible mess in Australia. We don't even need to try any further here, as the Amphaces keys are 100 years old and practically useless. What reveals it to be an Acanthosomatid are the tarsi, the cute little paws with only two tarsal segments, whereas most Pentatomidae have three segments. As you have correctly recognised, the length ratios of the antennal segments are very peculiar, especially the very long second segment compared to the very short third is almost unique to this genus."
