Identification

Bolton (2000) - A member of the Strumigenys emmae-group. Close to Strumigenys emmae and Strumigenys sutrix but immediately differentiated from both by the presence in miniteras of erect simple hairs on the occipital margin , small slender hairs on the promesonotum that contrast strongly with the broad cephalic pilosity, and presence of longitudinal rugulae on the pronotal dorsum.

Biology

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.

Description

Worker

HOLOTYPE. TL 1.8, HL 0.46, HW 0.36, CI 78, ML 0.14, MI 30, SL 0.22, SI 61, PW 0.23, AL 0.44. Closely related to emmae and answering the description of that species except as follows. Preapical dentition of mandible consists of a spiniform preapical tooth and a low bluntly rounded tubercle or welt that occupies most of the length of the inner margin between the preapical tooth and the apicodorsal tooth. Orbicular hairs of cephalic dorsum large and conspicuous; dorsolateral margin of head with a remiform apicoscrobal hair present and also with a second, similar but smaller hair that is located more posteriorly, on the margin of the occipital lobe. Occipital margin of head with 2 - 4 erect hairs. Ground-pilosity of pronotal dorsum of small spatulate hairs, contrasting strongly with the large orbicular hairs of the head. Pronotal dorsum weakly punctulate and with fine and quite dense longitudinal rugulae; mesonotum reticulate-punctate. Disc of postpetiole smooth.

PARATYPE. TL 1.7-1.8, HL 0.44-0.46, HW 0.35-0.37, CI 78-82, ML 0.13-0.15, MI 30-32, SL 0.21-0.22, SI 59-61, PW 0.21-0.24, AL 0.42 - 0.46 (6 measured).
