Mann's Carpenter Ants

Diagnosis. Emery (1925). - "Worker and soldier [major]. - Small species; caste dimorphism as pronounced as in Colobopsis, intermediates between soldier and worker do not appear to exist. Head of soldier somewhat longer than wide, strongly truncate anteriorly, surface of truncation comprising including cheeks, marginate laterally and anteriorly, and whole clypeus, frontal area of head depressed between frontal carinae, as in the typical species, and this impression divided by a median longitudinal carina; this frontal depression lacking in C. ulcerosus, Wheeler. Head of worker not different from most species of Myrmaphaenus. [Note: C. ulcerosus was transferred to Myrmaphaenus by Creighton (1951).] Clypeus of worker carinate; clypeus of soldier narrow and flat or with longitudinal sulcus (C. ulcerosus). Frontal carinae sinuate; antennal insertions situated as in Pseudocolobopsis. Mesosoma and petiole as in Myrmaphaenus. Queen and male. - Unknown.

Geographical distribution of species. - Cuba, Arizona.

Ethology. - Wood-dwelling species."
