Hello,
I am currently working with Murgantia histrionica (Hemiptera: Pentatomidae) and I need to distinguish males from females. I know that females are bigger than males, but size variation makes it hard to be 100% sure. Are there other traits that I can use (genitalia morphology, colour patterns, etc.)? If you can answer directly or provide papers it would be much appreciated.

As far as I know, the external morphology of the abdominal end, ventrally, is a bit different in males and females of pentatomids. It is therefore not difficult to distinguish the two sexes, by examination of these features. Regards,
