Camponotini
Camponotine Ants
Camponotini is a species-rich tribe of ants within the subfamily Formicinae, comprising 11 extant and 2 extinct genera with over 2,500 species. The tribe includes the well-known genus Camponotus (carpenter ants), along with Colobopsis, Polyrhachis, and several smaller genera. Members of this tribe are distinguished by their obligate association with the bacterial endosymbiont Blochmannia, which provides nutritional benefits. The tribe originated in the Eocene approximately 38.4 million years ago, likely in Australasia or the Indomalayan region.
Formicinae
formicine ants
Formicinae is a large and diverse subfamily of ants characterized by a single-segmented petiole in the form of a vertical scale, reduced stings, and the production of formic acid as a defensive compound. Members retain several primitive features including cocoons around pupae and ocelli in workers. The subfamily includes familiar ants such as carpenter ants (Camponotus), weaver ants (Oecophylla), and honeypot ants (Myrmecocystus). Formicines exhibit diverse ecological strategies including mutualism with sap-feeding hemipterans and specialized slave-making behaviors in some lineages.
