Monomorium antarcticum (Fr. Smith)

Common New Zealand Ant (Monomorium antarcticum)

The genus Monomorium contains over 300 species, with six species occurring in New Zealand, only two (or three) of which are native resp. endemic to New Zealand.

Altogether about five native species are known to exist within the Polynesian region.

~~~

The Common New Zealand Ant is actually not a species but a species complex, which contains at least four distinct species, and which needs further investigation.

The ‘species’ reaches a size of about 0,3 to 0,4 cm.

~~~

In the year 1936 (and again in the year 2002) a ant species was found on the island of Rapa / Austral Islands, that was identified as this ‘species’ – these ants, which seem indeed to be native to this island, however, most probably represent another, distinct, and hitherto undescribed species from the species complex.
