| Strumigenys lycosa|
Known from a few rainforest litter-sample collections.
Bolton (2000) - A member of the Strumigenys yaleopleura-group. S. lycosa separates easily from the other two Austral species of the group as Strumigenys minax has the disc of the postpetiole reticulate-punctate whilst Strumigenys yaleopleura has a laterally projecting flagellate hair on the upper scrobe margin at about the level of the eye (as well as one in apicoscrobal position). In addition, both minax and yaleopleura have projecting flagellate hairs on the dorsal (outer) surfaces of the middle and hind tibiae; such hairs are absent in lycosa.

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.
