Description
Kohout (2013): Forel was apparently misled by the original type locality given by Roger as Port Jackson and redescribed P. ammonoeides from Western Australia as P. chalchas. He also misinterpreted the short description given by Roger and considered a series of specimens collected by E. Mjöberg at Laura, Queensland (MNHU) to be P. ammonoeides. However, after examining these specimens, I consider they represent the species Polyrhachis cracenta.
