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 .^[1] Along with Triasacarus fedelei and an unnamed dipteran, it is the oldest arthropod found enclosed in amber.^[2]

Ampezzoa had a vagrant lifestyle on the surface of its host. It secreted waxy filaments, as a defense against predation and desiccation.^[1]
