Rhytidoponera metallica

Distribution
This taxon was described from Australia.

Biology
These ants are common in both native and urban habitats, being being abundant across a wide range of situations.

In rare instances these ants have been known to cause serious health problems for humans. In May 2009, a 4 year old girl in northern New South Wales was stung three times by this ant. Within minutes she developed anaphylactic shock and required adrenaline. She recovered but the concern is that future stings may cause similar reactions (Shattuck, 2009).

Crawley (1925) - Length 5.2 mm.

Slightly smaller than the above. The funicular joints are rather shorter, the sculpture on head and thorax is denser, the punctures less defined, on the postpetiole the sculpture is coarser, irregularly transversely rugose; the first segment of gaster transversely roughened; otherwise like inornata.
