Synonyms

Very large, widespread species that is common in the Darling Range. Nests in the Darling Range are often found in compacted laterite clay around the boles of trees, but are also made directly into soil. Their distribution likely includes all Australian states, although McArthur and Adams (1996) did not record it for the NT. (Heterick 2009)

Identification

Heterick (2009) - The distribution of erect and sub-erect setae on the propodeum distinguishes C. nigriceps from the similar Camponotus dryandrae; setae being continuous along the propodeal dorsum in C. nigriceps, and concentrated near the propodeal angle in C. dryandrae.

Camponotus clarior strongly resembles C. nigriceps, but the former have workers with a pale coloured head, concolorous with the mesosoma and node.
