 * Minor: Eyes smaller, its length less than one third of head length. Major:XXXX ..... Camponotus mystaceus

NOTES: mystaceus exanguis: very pale, decoloured (probable synonymy?) mystaceus kamae: very dark, brownish black. Chk head sculpture, maybe different

 * Propodeum swollen, sometimes raised over the mesonotum level, sometimes armed with small teeth. The posterior side of the propodeum normally concave, although sometimes only slightly so. Superior and lateral faces of the propodeum usually separated by ridges than can form small obtuse triangular teeth posteriorly. Petiole never slender or squamiform, but thick and normally cubical or rectangular (Subg. Orthonotomyrmex).....12

 * Mesosoma, petiole and gaster without any kind of pubescence or adpressed quetae. Long, thin white hairs present in mesosoma and petiole, but absent from the gaster except in the distal band of each tergite. Longitudinal striae present in mesosoma and petiole  ….. Camponotus liogaster


 * Mesosoma, petiole and gaster covered with notorious thick, small, white adpressed quetae. Some stout erect quetae present in mesosoma, petiole and gaster. Sculpture in head, mesosoma and petiole areolate and notorious ….. Camponotus scabrinodis

 * Head pubescence very long and dense, clypeus and genae almost completely covered and no patches of cuticula can be seen. Propodeum not ridged, but almost semispherical. Gaster densely covered with very long erect white hairs, its length comparable to the petiole height..... Camponotus cubangensis


 * Head pubescence abundant, but sparser, clypeus and genae with visible cuticula present in ample zones. Propodeum ridged at least in its posterios half. Gaster with sparse erect hairs, its length not comparable to petiole height ….. Camponotus mayri

 * Gaster covered with very dense, long yellow pubescence. Length of pubescent hairs bigger than distance between rows, thus covering the whole surface and almost completely covering the quitinous surface .....31
 * Gaster pubescence sparse to non-existant. Length of pubescent hairs smaller than distance between rows, thus not covering the whole surface and leaving ample zones of the quitinous surface exposed .....40
