Phlaeothripidae is a family of thrips with hundreds of genera.

They are the only extant family of the suborder Tubulifera, alongside the extinct family Rohrthripidae and are themselves ordered into two subfamilies, the Idolothripinae with 80 genera, and the Phlaeothripinae with almost 400.

Some 3,400 species are recognised in this family, and many are fungivores living in the tropics.

Idolothrips marginatus can attain a body length of up to 14 mm.

The group is distinguished by having the last abdominal segment modified into a tube-like structure – hence the suborder's name, which means "tube-bearers".
