The species exhibits, for the genus, an unusual sensillary pattern on the posterior abdominal segments. The arrangement and form of the five sensilla on the genital segment of most described species of Folsomia from the Palearctic are analysed and species divided into groups based on these characters. Several different lineages are detected.Keywords: morphology; new genus; spider; taxonomy; Australia; Queensland; Victoria [Australia]; Collembola; Folsomia; Isotomidae Australian Collembola; Lineage; Sensillary chaetotaxy; Species groups201010.1016/j.jcz.2010.01.0042016-02-24
