Ampezzoa triassica is an extinct species of gall mite described from the Carnian of northeastern Italy. It lived as a parasite of Cheirolepidiaceae trees. The only known specimen, preserved in amber, is 0.124 mm long. It resembles very much, in body shape and wax secretions, the contemporary gall mite Cymeda zealandica.{{Cite journal | last1 = Schmidt | first1 = A.

Ampezzoa had a vagrant lifestyle on the surface of its host. It secreted waxy filaments, as a defense against predation and desiccation.
