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 0.84, HW 0.55, CI 65, ML 0.32, MI 38, SL 0.48, SI 87, PW 0.34, AL 0.90. Mandible relatively short, with a preapical tooth. Dorsolateral margin of head in full-face view with 10 or more freely laterally projecting long filiform hairs, most of them arising from prominent tubercles. Shorter laterally projecting hairs also present on ventrolateral margin of head. Cephalic dorsum with numerous erect fine hairs that arise all over the surface from in front of level of eye to occipital margin. Ventral surface of head with shorter, sparser erect hairs. Dorsum of head finely and densely punctate-rugulose. Apical funicular segment moderately constricted basally. Promesonotal dorsum finely densely punctate-rugulose. Pleurae and side of propodeum everywhere densely punctate to reticulate-punctate. Pronotal humeral hair very long. Dorsal alitrunk with abundant erect simple hairs, filiform to sub flagellate, the number of pairs not easily counted; those on dorsolateral margin of mesonotum arise from discrete tubercles. Waist segments and first gastral tergite with abundant similar hairs. Dorsal, ventral and lateral surfaces of hind femur with rows of suberect/erect hairs; dorsal (outer) surfaces of hind tibia and basitarsus each with long erect freely projecting hairs. Propodeal teeth long, much longer than basal width in profile and weakly upcurved. Petiole in profile claviform, in dorsal view much longer than broad.

The single Sumatran specimen measures HL 0.86, HW 0.58, CI 67, ML 0.32, MI 37, SL 0.48, SI 83, PW 0.33, AL 0.89.
