Triasacarus fedelei 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 0.210 mm long.[1] Along with Ampezzoa triassica and an unnamed dipteran, it is the oldest arthropod found enclosed in amber.[2]

It is possible that Triasacarus induced the formation of galls on the host plant.[1]
