Specimen Labels

Described from southern Victoria, this species had previously been recorded from high rainfall areas near the south coast (WA), notably the Porongorup and Stirling Ranges. Recently, a worker was collected by vegetation vacuuming in the Worsley mining area south-east of Perth. This constitutes a first record for Jarrah-Marri woodland in the Darling Range.
