Identification

Scapes and legs with abundant erect setae; eyes strongly protruding from sides of head; propodeum, meso and metathorax highly fused, sutures very weak, forming a single unit that articulates with the prothorax; dorsal profile with dorsal and posterior faces of propodeum not differentiated; propodeum strongly laterally compressed, tectiform; back of head with small vertex collar or neck; appressed pubescence on first gastral tergite sparse.

Major worker absent.

Color variation: specimens from the Pacific side of Costa Rica have a dark head with yellow on the malar spaces and a red brown mesosoma and metasoma (upper figures above); specimens from the Atlantic side are more uniformly red brown (lower figure above). (Jack Longino)

Biology

Jack Longino: Camponotus chartifex inhabits mature lowland rainforest. Workers are most often encountered as isolated foragers, day or night. Like Camponotus in general, they appear to be generalized scavengers with a predilection for sweets.

This species and its relative, Camponotus nitidior, build nests of sewn-together leaves (Wilson 1981, Fernández 2002). They use larval silk to attach leaves together and to make silk sheets and baffles. The nest walls are a combination of leaves and silk sheets. The silk sheets and baffles are a combination of silk and masticated plant fibers.

I have only found one nest of C. chartifex. At Tortuguero I found a nest between two leaves. The leaves were sewn flat together, with the nest sandwiched between them. The nest was roughly circular, about 4cm diameter.

Fungi

This species is a host for the fungus Ophiocordyceps camponoti-chartificis (a pathogen) (Araujo et al., 2018).
