Introduction
The family Brachychthoniidae is large and cosmopolitan, with 11 genera and 169 species (Schatz et al. 2011; Subias 2011). They are diverse and abundant in forest litter and soil, grassland, and Arctic and Subarctic habitats (Norton & Behan-Pelletier 2009). They are very small and, perhaps for that reason, very little is known of their feeding habits or other aspects of their biology. The Australian fauna includes seven identified species in four genera, as well as records of unidentified species in two more genera. Some of the records may be questionable, and are based on misidentifications or misspelled names (see Colloff & Halliday (1998) for details). Unidentified species have been recorded from Australia a number of times as listed for each genus, and unidentified Brachychthoniidae were also reported by Springett (1979, as Brachypthonidae), Noble et al. (1996) and Adolphson & Kinnear (2008).
Marshall et al. (1987) recorded Liochthonius brevis (Michael, 1888) from Australia. This observation was based on the record of Brachychthonius cf. perpusillus (Berlese, 1910) from Australia by Womersley (1945), and the fact that B. perpusillus was considered to be a synonym of L. brevis. However, Womersley's identification of B. perpusillus was only tentative, and Lee (1982) considered that the Womersley specimens were actually Liochthonius simplex (Forsslund, 1942), and not L. perpusillus or L. brevis.
