Biology

Explore Overview of Strumigenys 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 2.0, HL 0.53, HW 0.42, CI 79, ML 0.25, MI 47, SL 0.28, SI 67, PW 0.24, AL 0.55. Characters of signeae-complex. Apicoscrobal hair fine and simple; a second similar hair present anterior to it on upper scrobe margin, just posterior to level of eye. Cephalic dorsum with a transverse row of 4-6 short erect simple hairs at occipital margin and with several pairs or short transverse rows of similar standing hairs anterior to this, around highest point of vertex. Pronotal humeral hair stiff and simple, pronotal dorsum also with a pair of erect simple hairs anteriorly. Mesonotum with a single pair of erect simple hairs. Dorsum of pronotum and anterior mesonotum unsculptured except for periphery which is shagreenate to superficially punctulate. Posterior mesonotum and propodeal dorsum evenly but superficially punctate. Side of alitrunk entirely smooth. Propodeal teeth acute, subtended by a narrow lamella; posterior (free) margin of lamella concave and approximately paralleling the margin of the declivity. Petiole node in dorsal view broader than long, weakly superficially punctate. In profile lateral spongiform lobe of petiole small, confined to posterior portion of node. Disc of postpetiole unsculptured. First gastral tergite with standing hairs stiff, fine and simple. Basigastral costulae shorter than disc of postpetiole.

Type Material

Holotype worker, Malaysia: Pahang, Fraser's Hill, 1350 m., below Kuantun ridge, 17.iii.1993, #9 (Lobl & Calame) (Musee d'Histoire Naturelle Genève).
