Strumigenys bubisnoda group

Nothing is known about the biology of Strumigenys bubisnoda.


Bolton (2000) - The only member of the Strumigenys bubisnoda-group. Because of the remarkably flattened head and grossly swollen postpetiole this species should not be confused with any other from the regional fauna.

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 4.0, HL 1.22, HW 0.72, CI 59, ML 0.13, MI 11, SL 0.43, SI 60, PW 0.46, AL 1.10. Upper scrobe margins posterior to frontal lobes closely approximated and roughly parallel; behind level of eyes flaring outward at almost a right-angle until nearly twice the former width. Anterior part of these margins with a number of small flattened projecting hairs, similar in shape and size to those on leading edge of scape. Maximum diameter of eye 0.12. Lateral spongiform lobe of petiole extends almost the entire length of the side of the node. Enormously inflated postpetiole has maximum width in dorsal view 0.59, maximum length in same view 0.42; maximum depth in profile 0.40, in all cases ignoring the spongiform tissue. Sculpture of dorsal and lateral alitrunk, and on petiole and postpetiole, is of separated punctures rather than reticulate-punctation. Basal half of first gastral tergite and sternite smooth, apical half of each sclerite densely punctulate.
