Bolton (2000) - A member of the Strumigenys thaxteri-group. Pilosity on the leading edge of the scape is damaged or not clearly visible in the holotype and single other specimen available. For this reason I have keyed the name twice, running out reticeps through each lug of the important couplet dealing with curvature of hairs on the scape. Discovery of further material will allow determination of its real track through the key.

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.

Bolton (2000) - TL 1.9, HL 0.48-0.52 (excluding clypeal tooth), HW 0.38, CI 73-79, ML 0.04, MI 7-8, SL 0.23-0.24, SI 61-63, PW 0.26-0.27, AL 0.52-0.56 (2 measured).
Easily isolated from all other Neotropical members of Pyramica as it is the only known species to have the following series of characters in combination, as well as the group characters listed above.
1 Midpoint of anterior clypeal margin extended into a sharp triangular tooth that projects forward over the mandibles.
2 Clypeus, and a broad triangular area of the cephalic dorsum immediately behind the clypeus, glassy smooth, contrasting strongly with the densely reticulate-rugulose remainder of the dorsum.
3 Dorsum of clypeus with numerous fine acute simple hairs that are all erect and shallowly curved posteriorly.
4 Head in full-face view with 3 pairs of flagellate hairs: first pair arising dorsally just behind the frontal lobes, directed anteriorly; second pair on upper scrobe margin just in front of level of eye, freely projecting laterally (omitted from Kempf' s (1969) figs. 7 and 8); third pair on side of occipital lobe, freely projecting laterally.
Promesonotum with a median carina; on each side of the carina pronotum with sparse feeble posteriorly divergent costulae on a smooth surface. Mesonotum with some punctulate sculpture and the propodeal dorsum reticulate-punctate. Petiole node punctate and feebly rugulose dorsally. Pronotal humeral hair long, fine and flagellate.
