Minor worker: propodeum very narrow and elongate, in cross section tectiform (tent-like, like an inverted "V"), without a distinct angle separating lateral and dorsal faces; clypeus with median longitudinal keel; mesosoma very elongate and narrow in lateral view; abundant erect setae on sides of head, mesosomal dorsum, and gaster; scapes with subdecumbent short pubescence and no erect setae; in face view head widest at mandibular insertions, tapering posteriorly; head behind eyes subtrapezoidal, long and tapering; size large (WL 4.3mm, n=1).

Similar species: ager.

Natural History

This species is like a smaller version of C. ager, and seems to have similar habits. I know it only from occasional nocturnal foragers in mature forest areas.
