Google keeps suggesting I’m looking for “Hegemony”, but I’m not. This is Hegemona, a large darkling beetle we encountered in Belize:
These insects are large- about an inch long- and appear nearly black in the field. Under soft lighting, structural colors in the elytra emerge spectacularly. I suspect the bright alternating stripes serve to warn predators of the beetle’s toxicity, as it emitted a noxious odor when handled.
Thanks to Kojun Kanda for the identification.
