Bamboosiella australis (Pitkin)

Antillothrips australis Pitkin 1977, p 54 .

Known only from a few specimens of both sexes taken in eastern Australia (SE Queensland, and NSW near Sydney and Bateman’s Bay), this species closely resembles B. cingulata apart from the differences noted in the key above.
