- Description: Collembola is one of the major functional groups in soil as well as a model taxon in numerous disciplines. Therefore the accurate identification of specimens is critical, but could be jeopardised by cases of cryptic diversity. Several populations of six well characterised species of springtails were sequenced using the COI barcode fragment as a contribution to the global Collembola barcoding campaign. Each species showed high intraspecific divergence, comparable to interspecific sequence divergence values observed in previous studies and in 10 congeneric species barcoded here as a reference. The nuclear marker, 28S, confirmed all the intraspecific lineages found with COI, supporting the potential specific status of these entities. The implications of this finding for taxonomy and for disciplines relying on species names, such as evolution and ecology, are discussed.

- Description: In the early 1970s several slides of an unusual Collembola (Springtail), labelled from Muston, Kangaroo Island by Herbert Womersley in 1943, were found in the South Australian Museum. These slides were in poor condition and were labelled "Ceratrimeria cooperi" but the species was never described. Extensive collections in South Australia throughout the 1970s and early 1980s showed that the species occurred fairly widely in the State, and it seemed to be most abundant on Kangaroo Island. Later taxonomic work on the related genus Ceratrimeria and allied genera in Australia has indicated that the South Australian species belonged to a new genus, possibly one of the few genera of Collembola likely to be endemic to South Australia.
