Camponotus (Colobopsis) leucodiscus Wheeler, 1919: 117. Holotype dealate queen (by monotypy), British North Borneo (E. B. Kershaw) (MCZC) [examined via image on MCZbase: MCZ-ENT00021564]

Camponotus (Colobopsis) leucodiscus ; Wheeler, 1919: 118. Description of worker, soldier.

Camponotus (Myrmamblys) bellus leucodiscus ; Emery, 1925: 138. Placement in Camponotus (Myrmamblys) and subspecies of Ca. bellus .

Workers associated with Ca. leucodiscus (i.e., matching the striking black and white color pattern on the gaster of the holotype queen) lack the matte integument and pilosity of Ca. bellus , and are instead shiny and with sparse pilosity, as described above for Ca. adustus . They apparently differ from workers of Ca. adustus by the longer, lower petiole and by the color pattern on the gaster. Both taxa that are here elevated to species are part of a larger assemblage of ants in the Ca. reticulatus group that need comprehensive taxonomic study.
