Minor worker: habitus similar to C. novogranadensis; scapes with fine appressed pubescence, no erect setae; cheeks with sparse appressed pubescence only, no erect setae; propodeum with flat, well-differentiated dorsal and posterior faces, meeting at a shallow angle, dorsal face longer than posterior face; propodeum strongly laterally compressed, tectiform; propodeal suture distinct across dorsum and down to metathoracic spiracles, breaking dorsal profile; first gastral tergite with very sparse, short appressed pubescence and sparse erect setae; integument color dark red brown.
Major worker: head subquadrate; lateral margins of head devoid of projecting setae; clypeus with a pronounced median keel; face entirely smooth and shiny.
Similar species: novogranadensis.
Natural History
I know this species from three localities. At La Selva Biological Station, a lowland rainforest site, the species has been collected in canopy fogging samples from the ALAS project, and in recent treefalls. At Tortuguero, another lowland rainforest site, I collected a nest in a vertical rotten stick. Mauricio Ramirez collected workers in the San Luis Valley, a moist forest habitat on the Pacific slope below Monteverde, at 1150m elevation.
