Identification

Bolton (2000) - A member of the Strumigenys appretiata-group. The three species of the group in which the ventral lobe of the postpetiole is vestigial or absent (appretiata, Strumigenys hadrodens, Strumigenys xenochelyna) are easily separated by the characters given in the keys and the notes appended to hadrodens and xenochelyna.

Biology

Explore-icon.png 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

Bolton (2000) - TL 1.9-2.0, HL 0.52-0.56, HW 0.46-0.50, CI 88-89, ML 0.09-0.10, MI 17-18, SL 0.21-0.23, SI 45-46, PW 0.26-0.28, AL 0.50-0.54 (2 measured).

Ventral spongiform lobe of postpetiole reduced to a minute vestige anteriorly on the sternite. Conspicuous flagellate hairs present at the pronotal humeri, a pair of long fine sub flagellate hairs on the mesonotum and a number of flexuous to flagellate fine hairs on the first gastral tergite. The pronotum is almost entirely smooth, with only the faintest scattered vestiges of longitudinal sculpture, but the mesonotum and propodeum (including the upper half of the declivity) are reticulate-punctate. Basigastral costulae are short and widely spaced, the first gastral tergite is otherwise glassy smooth. Petiole node in dorsal view slightly broader than long to about as broad as long, not markedly transversely rectangular nor with acute prominent anterolateral angles.

Type Material

Bolton (2000) - Holotype worker, BRAZIL: Santa Catarina, Nova Teutonia, x.1953 (F. Plaumann) (Museum of Comparative Zoology) [examined].
