Ironomyiidae

Definition

A small family of flies (order Diptera) comprising three extant species in the single living genus Ironomyia, endemic to Australia, plus numerous extinct fossil genera from North America and Asia dating to the Early Cretaceous. Formerly treated as a subordinate group within Platypezidae.

Etymology

From the type genus Ironomyia (Greek iron 'wool' + myia 'fly') + -idae family suffix

Example

The Australian endemic Ironomyia nigromaculata represents one of only three living species in Ironomyiidae, a relict family whose fossil record reveals a broader Cretaceous distribution across Laurasia.
