Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera ''Myrmoteras'' and ''Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of the abdom ...
