Anterhynchium

thumb|Anterhynchium flavomarginatum umenoi. A female searching a caterpillar of moth. Iriomote Is., Japan Anterhynchium is an Afrotropical, Indomalayan, Australian and Palearctic genus of potter wasps. As in many species of wasp, female wasps defend against predation using a modified ovipositor to sting predators. Like some other wasps in the Vespidae family, male wasps can produce a "pseudo-sting" with two sharp spines on either side of their genitals; however, unlike in the females, this "sting" is venomless.
