The largest species of the genus, C. godmani was long known only from the holotype gyne from Ecuador. The known queens and tentatively assigned males have yet to be collected with any workers. The queen has an unusually shaped notch on the apex of the pygidium that is presumed to facilitate the movement of the sting. (De Andrade 1998)

De Andrade (1998) - The basalmost species of the longiceps clade clade differing from all others by the distance between the frontal carinae, about 2/3 of the head width instead of about 1/3 and by the superficial gastric striae.
C. godmani is the largest species of the genus. A striking character shared by godmani, Cylindromyrmex antillanus and Cylindromyrmex meinerti is a notch on the apex of the pygidium, more impressed in godmani and antillanus.

De Andrade (1998) - The isolate males described here as godmani are tentatively referred to this species for the following reasons: 1- frontal carinae and genitalia similar to those of meinerti; 2- tibiae partially yellowish brown (yellowish in the gyne): 3- they originate from the geographic range of godmani; 4- the males of the other species occuring in central and northernmost countries of South America, i. e. Cylindromyrmex striatus, Cylindromyrmex whymperi, Cylindromyrmex boliviae, Cylindromyrmex brevitarsus are already known, except Cylindromyrmex escobari. I exclude the possibility that the two males referred here to godmani could be attributed to the Colombian escobari because this specie belongs to another clade the male of which (brevitarsus) differs significantly from those of the longiceps clade by the frontal carinae and genitalia. If the attribution of these two males to godmani is not correct, they should represent an undescribed species.
