Formicidae, Hymenoptera, Insecta, Arthropoda, Animalia
Southern Mexico to Northern Argentina (Brown 1976). Costa Rica: wet to moist forest of both slopes to mid-elevations; more abundant at mid-elevations than in the lowlands.
Dorsal surface of head distinctly striate to or nearly to the nuchal carina; disc of first gastral tergite distinctly and evenly striate over its entire surface, striation curved-transverse; large, slender species.
This strikingly large species I have only seen as foragers in wet forest, on the forest floor, and often nocturnal. I have never seen a nest.
Formica chelifera Latreille 1802:188. Syntype worker: South America.
