Bolton (2000) – A member of the cordovensis complex in the Strumigenys mandibularis-group. Closely related to Strumigenys cordovensis but with enormously elongated mandibles, a longer narrower petiole node and smaller femoral gland bullae.

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 4.2, HL 0.88, HW 0.69, CI 78, ML 1.20, MI 136, SL 0.72, SI 104, PW 0.39, AL 0.83. Characters of cordovensis-complex. Distal preapical tooth very long and narrowly spiniform, much closer to apicodorsal tooth than to proximal preapical tooth. With mandible in profile distal preapical tooth strongly elevated; shaft of mandible distinctly upcurved from close to midlength to level of distal preapical tooth, thereafter flexed weakly downward to the apical fork. Standing hairs on head and alitrunk stiff, narrowly remiform apically: one in apicoscrobal position; a pair on vertex close to occipital margin; one at each pronotal humerus; absent from mesonotum. Petiole, postpetiole and basal quarter of first gastral tergite with fine curved filiform to subflagellate hairs. Bullae of femoral glands short and subovate, located at or proximal of the dorsal mid length on the middle and hind femora. Propodeal lamella acutely bitriangular to bispinose, lower lobe longer than upper. Lateral spongiform lobe of petiole large and extends forward on side to level of anterior face of node. Petiole node reticulate-punctate, as long as broad in dorsal view. Lateral and ventral spongiform lobes of postpetiole massive. Disc of postpetiole sparsely longitudinally costulate. Basigastral costulae sharply defined, longer than width of posterior spongiform collar of postpetiole but shorter than disc.
Paratypes. TL 4.2, HL 0.88-0.92, HW 0.70-0.73, CI 79-80, ML 1.22-1.24, MI 133-141, SL 0.74-0.75, SI 101-107, PW 0.39, AL 0.82-0.82 (2 measured).
