Distribution based on specimens
Strumigenys were once thought to be rare. The development and increased use of litter sampling methods has led to the discovery of a tremendous diversity of species. Many species are specialized predators (e.g. see Strumigenys membranifera and Strumigenys louisianae). Collembola (springtails) and other tiny soil arthropods are typically favored prey. Species with long linear mandibles employ trap-jaws to sieze their stalked prey (see Dacetine trap-jaws). Larvae feed directly on insect prey brought to them by workers. Trophallaxis is rarely practiced. Most species live in the soil, leaf litter, decaying wood or opportunistically move into inhabitable cavities on or under the soil. Colonies are small, typically less than 100 individuals but in some species many hundreds. Moist warm habitats and micro-habitats are preferred. A few better known tramp and otherwise widely ranging species tolerate drier conditions. Foraging is often in the leaf litter and humus. Workers of many species rarely venture above ground or into exposed, open areas. Individuals are typically small, slow moving and cryptic in coloration. When disturbed individuals freeze and remain motionless. Males are not known for a large majority of species.

Holotype. TL 1.9, HL 0.47, HW 0.38, CI 81, ML 0.25, MI 53, SL 0.28, SI 74, PW 0.25, AL 0.50. Dorsolateral margin of head with 2 freely laterally projecting flagellate hairs, one at level of eye, the other apicoscrobal. Side of alitrunk entirely reticulate-punctate, without smooth shining patches on pleurae. Bullae of femoral glands very conspicuous, those on fore femora distinctly larger than those on middle and hind femora. Basitarsus of hind leg with 2 very long erect fine flagellate hairs on its dorsal (outer) surface; a single similar hair on dorsal (outer) surface of hind tibia. Propodeal teeth short and narrowly triangular. With petiole in profile height of anterior face of node about equal to length of dorsum of node, the two surfaces meeting through a well defined but blunt anterodorsal angle. Petiole node in dorsal view broader than long, roughly transversely rectangular. Basigastral costulae very short, their length on the tergite hardly greater than thickness of limbus, very much shorter than length of the reticulate-punctate postpetiole disc.
Paratypes. TL 1.8-1.9, HL 0.46-0.49, HW 0.37-0.39, CI 79-81, ML 0.24-0.25, MI 50-53, SL 0.27-0.28, SI 71-74, PW 0.24-0.25, AL 0.46-0.50 (6 measured).
