Jack Jumpers are ants well known to most people in Australia. Due to dramatic interspecific similarity, specimens have often been identified as Myrmecia pilosula. In his latest work published in Zootaxa, Robert Taylor reviews the present status of Myrmecia pilosula complex and describes 4 new species bringing the species tally of this charismatic group to six: M. banksi, M. croslandi, M. haskinsorum, M. imaii, M. impaternata and M. pilosula.
