Terayama, M. (1999) Ant genus Camponotus Mayr (Hymenoptera; Formicidae) in Japan. Memoirs of the Myrmecological Society of Japan 1: 25-48.

Total length around 2.5 - 3 mm in minor workers and around 5 mm in major workers. Head and mesosoma yellowish brown to reddish brown (sometimes blackish brown); gaster black.

This species is distinguished from C. nipponicus by the much longer heads of its major workers (head length about 1.10 mm, versus 1.00 - 1.05 mm in C. nipponicus), and the shape of the anterior margin of the head, which has a pair of blunt projections visible in full face view.
This is an arboreal species.
