Similar to Carebara inca with the following differences:

A longitudinal and less narrow stripe, subopaque. Eyes reduced to 1 ommatidium; lamellae of metapleural lobes low; dorsum of head densely sculptured with very small, shallow foveolate punctures, broadly separated; dorsum of promesonotum with dense, fine longitudinal striation mixed with scattered small punctures; sloping face of propodeum densely reticulated. Scapes, dorsum of head, promesonotum and legs with appressed to feebly curved pubescence, denser on head. Body nearly naked of long hairs, with only a few (about 0.05 mm) distributed as follows: four in the clypeal area; two on each frontal lobe; four on promesonotum, none on propodeum, none on legs; two on petiole, two on the postpetiole, two on first tergal dorsum. Body brown, appendages lighter.

Fernández (2006) - Eyes reduced to 1 ommatidium. Lamellae of metapleural lobes low. Dorsum of head densely sculptured with very small, shallow foveolate punctures, broadly separated; mid dorsum to almost all of promesonotum with dense, fine longitudinal striations mixed with scattered small punctures, periphery of promesonotum, dorsal and posterior face of propodeum and petiole densely reticulated. Postpetiole and gaster smooth and shining. Scapes, dorsum of head, promesonotum and legs with appressed pubescence, denser on head. Body nearly naked of long hairs, with only few (about 0.05 mm) distributed as follows: four on clypeal area; two on each frontal lobe; two on head (each one near occipital corner), eight on promesonotum, two on propodeum, none on legs; two on petiole, four on postpetiole, several on first tergal dorsum. Body brown, appendages lighter, most of gaster dark brown.
