Southern Mexico to Southern Brazil, Bolivia (Brown 1976). Costa Rica: throughout in wet to dry forest, to 1200m.


The smallest Odontomachus species in Costa Rica (head length including mandibles less than 2.5mm); face to near margin of vertex striate; color light or dark brown; top of first gastral segment very densely punctulate, opaque, longitudinally striate over a posterior portion of variable extent.

Natural History

This is a relatively common species in Costa Rica, as revealed by its frequent presence in samples of sifted leaf litter from the forest floor (Winkler samples). However, I have rarely seen nests. I once observed a nest under a stone in the moist forest/dry forest ecotone at Maritza station in the Guanacaste Conservation Area. I once observed a dealate queen that fell out of a Cephaelis stem I was dissecting in Braulio Carrillo National Park.

Type Data

Odontomachus haematodes r. meinerti Forel 1905:156. Syntype worker: Venezuela, Bolivar: Las Trincheras.

Odontomachus haematoda subsp. minuta Luederwaldt 1918:36. Syntype worker: Brazil, Mato Grosso. First available use of Odontomachus haematodes subsp. pubescens var. minuta Emery 1894:146.

This species has been known as O. minutus until recently, with meinerti a junior synonym. When ant taxonomists began enforcing the rule that quadrinomials are unavailable names (Bolton 1995), meinerti became the senior synonym.
