Specimen Labels

Known only from the queen holotype, nothing is known about the biology of Camponotus postangulatus.


A member of the subgenus Myrmostenus.

Mackay (1997) - This species is very similar to Camponotus longipilis but can be separated easily as the occipital angles are well differentiated, and there are no erect hairs on the ventral surface of the head. The surface of the clypeus is strongly convex with a well differentiated clypeal carina.

This species is closely related to C. longipilis, but is distinct enough to be regarded as a valid species. In addition, the type locality for both species is the same. The characters in the key and in the diagnoses of the two species should be sufficient to separate the two species.
