The Mesostoinae is a subfamily of wasps endemic to Australia.It contains four genera:

Andesipolis
Hydrangeocola
Mesostoa
Proavga

The members of this family display sexual dimorphism, males are brachypterous, which means that they have reduced, non-functional wings. A unique feature of this subfamily is that all the known species are primary gall formers on Banksia.
