Identification
Fernández (2004) - A member of the Carebara escherichi species complex. This species is easily recognized by its promesonotal sculpturation. The anterior half is more or less longitudinally striated and the posterior half densely reticulated. In side view, the propodeum forms a slightly angle between the dorsal and sloping faces. The head has four hairs near the occipital corners.

Description
Worker
Holotype (Paratypes n=2): HW 0.31 (0.31); HL 0.36 (0.35); SL 0.19 (0.18); PW - (0.20-02.4); WL 0.29 (0.27-0.28); GL 0.36 (0.34-0.35); TL 1.24 (1.20-1.22); CI 86 (88); SI 60 (58). [The bad mounting of de ecuatorian paratype prevents some measurements. The scapes and legs are broken].
As. Carebara inca with the following differences:
A longitudinal and less narrow stripe, subopaque. Eyes reduced to 1-2 ommatidia. Propodeum slightly angulated. Propodeal spiracle circular, spiracle low and nearly in contact with bullae of metapleural gland. Dorsum of head densely sculptured with deep foveolated punctures whose diameters are smaller than the spaces separating them; dorsum of promesonotum anteriorly with a very fine and irregular longitudinal rugulae, posteriorly with dense and well-marked reticulae, somewhat more widely spaced in propodeal dorsum; sloping face of propodeum without transverse rugulae. Gaster smooth and shining. Dorsum of head with fine appressed pubescence, dorsal promesonotum with only a little appressed pubescence; rest of body without. Short curved and scattered pubescence on femora and tibiae. Long hairs (more or less three times longer than short hairs) few and distributed as follows: four in the clypeal medial area; two over each frontal carinae; four on the posterior part of head (two on each side, near the occipital border); twelve on promesonotal dorsum; two on propodeal dorsum; two (and four medium size) on the petiole, four on the postpetiole, several scattered on tergal dorsum; more or less four median dorsal hairs on each tibia. Body brown, gaster darker.
