Identification:

These are the New World "army ants", whose workers can be recognized by the following features: (1) eye reduced to a single ommatidium or absent; (2) clypeus narrow (back to front), so that the antennal insertions are close to the anterior margin of the head; (3) antennal sockets not concealed by frontal carinae; and (4) pygidium simple, unarmed. In addition, the pronotum and mesonotum are fused into a single structure, and the sting is present and functional. The postpetiole may be present or absent. Most of these features, except the simple pygidium, are seen in some species of the subfamily Cerapachyinae (q.v.).

Notes:

Represented in California by a single genus (and about 10 species), the Ecitoninae are most prevalent in the Neotropical region. All are nomadic, predatory army ants.
