Camponotus rufonigrus Shattuck & McArthur, 2002 Specimen labels

This species is known from a limited number of localities in southern South Australia. Two collections consists of single minor workers, while one (from Cambrai) contains nine minor workers collected at six different times during January and February, 1972. Thus this species has been rarely collected and then generally in small numbers. The limited biological information suggests that this species occurs on sand.

Identification

Anterior clypeal margin broadly convex across its entire width. Tibiae and scapes lacking erect hairs; propodeum with more than 10 erect hairs which are scattered along the entire dorsal surface. Petiolar node angular or broadly rounded above, the anterior face at most only slightly shorter than the posterior face. Black head contrasting with red mesonotum.
