    Abstract

    As part of a modern review of all Australian Collembola families, a key is provided to the nine genera of Brachystomellidae currently known from Australia, their morphology is compared, their distribution within and outside Australia is noted and the high diversity of genera in southern regions emphasised. Three Australian genera are endemic, five are also found in South America, South Africa and/or New Zealand and one has a cosmopolitan distribution. The distribution, ecology and habitat preferences of Australian genera are compared. Two genera, Cassagnella Najt & Massoud and Rapoportella Ellis & Bellinger, are newly diagnosed and additions to the description of C. anomala Womersley are given. Australian Cassagnella species appear restricted to southern, humid regions and C. anomala possesses some characters that indicate it is adapted to living in habitats that are periodically flooded. A new species, Rapoportella edwardi sp. n. is described in the rarer genus from drier eucalypt forests. The effect of agricultural practices on an introduced species of Brachystomella is noted and its indicator value emphasised. Possible threats to the endemic genera and species are noted.
