Flat Carpenter Ants

Diagnosis. Emery (1925). - "Worker and queen. - Entire body flat, appearing as if these ants have been crushed; caste dimorphism only slightly pronounced. This small group of ants resembles C. crassus, of which all body parts are lengthened and depressed. Head extremely depressed, especially in C. obtritus, Emery and depressus, Mayr, head narrower anteriorly than posteriorly, with eyes set very close to posterior head margin which is almost straight in minors; lateral head margins more-or-less parallel in majors; in majors, eyes set more anteriorly. Clypeus and frontal carinae roughly same as Myrmobrachys; in C. obtritus carinae very short, and antennal insertions situated almost at midlength of carinae. Mesosoma more-or-less elongate and depressed; dorsum continuous; pronotum rounded or subbordered. Petiolar scale thick or almost nodiform. Legs long, bristly with black setae, tibiae more-or-less compressed, highest degree of compression occurring in C. obliterus. Cuticle black, matte.

Geographical distribution of species. - Brazil: Amazon Basin, Sao Paulo."
