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 2.6, HL 0.75, HW 0.62, CI 83, ML 0.34, MI 45, SL 0.40, SI 65, PW 0.32, AL 0.70. With characters of koningsbergeri-complex. Preocular concavity forms a shallow depression on ventral surface of head. Upper scrobe margins not constricted above eye, only extreme outer arc of eye visible in full-face view, or eye not visible. Depression across posterior vertex of head shallow, weakly developed. Pronotum without a pair of short standing hairs close to anterodorsal margin. Pronotal humeral hair stiff, straight and simple. A single erect pair of hairs on mesonotum. Katepisternum mostly smooth but metapleuron and side of propodeum uniformly reticulate-punctate. Bullae of fem oral glands absent on middle and hind legs. Lamella on propodeal declivity conspicuous. Standing hairs on first gastral tergite simple or slightly expanded and flattened toward the apex.
Paratypes. TL 2.5-2.6, HL 0.71-0.76, HW 0.58-0.62, CI 82-83, ML 0.32-0.34, MI 43-46, SL 0.40-0.41, SI 65-69, PW 0.30-0.32, AL 0.70 (4 measured).
