Up until 2012 it contained a single species, U. scabrosus, known from Belém, Brazil; Brisbane, Australia; Singapore, and Angola.

In 2012 a new extinct species, U. eocenicus, was described from the lowermost Eocene of France by Patricia Nel and André Nel in 2012.

[2] The group name is in honour of Jindřich (or Heinrich) Uzel, a Czech entomologist who published the first monograph on the thrips.
