Comments Abstract: "A new sibling species of the primitive Australian ant Myrmecia pilosula has a chromosome number of n = 1... Males are haploid, as in other Hymenoptera, and their somatic cells contain only a single chromosome. This new species is potentially of great importance in both laboratory and field studies on gene organization."
