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 3.1, HL 0.94, HW 0.80, CI 85, ML 0.40, MI 43, SL 0.50, SI 63, PW 0.38, AL 0.84. With characters of koningsbergeri-complex. Preocular concavity forms a short, shallowly depressed basin on ventral surface of head. Upper scrobe margins weakly constricted above eye but sufficient to allow most of arc of eye to be visible in full-face view. Upper scrobe margin with minute irregularities from which small hairs arise, but without a row of triangular teeth, without a jagged appearance. Depression across posterior vertex of head broad but very shallow. Pronotum without a pair of short standing hairs close to anterodorsal margin. Pronotal humeral hair very short, simple. All erect hairs on cephalic dorsum, and single pair on mesonotum, short. Katepisternum mostly smooth, metapleuron usually with a small smooth patch. Bullae of femoral glands absent from middle and hind legs. Lamella on propodeal declivity very narrow, almost carina-like, in profile its posterior (free) margin concave and following the shape of the edge of the declivity. Standing hairs on first gastral tergite mostly or entirely weakly expanded and flattened toward the apex.
Paratypes. TL 2.8-3.1, HL 0.82-0.96, HW 0.70-0.82, CI 85-88, ML 0.33-0.40, MI 40-45, SL 0.40-0.52, SI 57-63, PW 0.32-0.40, AL 0.72-0.85 (12 measured).
