A third species in the rare Australian ant genus Peronomyrmex Viehmeyer (Hymenoptera: Formicidae)

A single specimen of the third species in the rare Australian ant genus Peronomyrmex, a member of the subfamily Myrmicinae, has been located in the collections of the Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts. This specimen was thought to have been lost and its species-level identification was uncertain. It is now known to represent a third species, here named P. greavesi, and confirms the presence of this genus in northern Queensland. The genus is now known from four specimens stretching from Victoria northwards to northern Queensland, a distance of over 2000 km.
