Specimen Label

This species inhabitats forest and apparently nests in rotten wood as well as in soil. It has also been taken in oil palm plantations. Some specimens were collected from carrion traps baited with iguana meat. Longino (pers. comm.) reports finding a nest beneath a rotten log; the ants burrowed into the soil on exposure. (Lattke 1995)


A member of the concinna species group. Vertexal margin concave in frontal view; mandibles with longitudinal costulae; declivitous propodeal face with longitudinal striae superiorly and basally transverse rugae; petiolar node transverse; postpetiolar sternum mostly transversely strigulate; no metacoxal tooth. (Lattke 1995)
