Hairs lacking, except on the mandibles. Body surfaces microreticulate, opaque. Probolomyrmex is distributed in tropical and subtropical areas of the world. There are 13 named species, all of which are very rare. Most are known only from their type-localities.
Colonies are small, often including only several individuals.
The biology has been scarcely studied. The genus inhabits leaf-litter or soil in forest. Nests have been collected from fallen dead branches, other rotting wood or the soil under stones.
