A specimen was collected from a rainforest litter sample.
Bolton (2000) - A member of the elapoma complex in the Strumigenys lyroessa-group. For separation from Strumigenys elapoma see there. In dimensions and general appearance morphica bears a striking resemblance to Strumigenys liophila, the two together having longer scapes and femora and a narrower head than is usual in the group. S. liophila however has apical mandibular dentition characteristic of the lyroessa-complex and a smooth patch on the katepisternum.

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 2.3, HL 0.64, HW 0.45, CI 70, ML 0.18, MI 28, SL 0.32, SI 71, PW 0.28, AL 0.64. Characters of elapoma-complex. Upper scrobe margin with anteriorly curved small spoon-shaped hairs that are about the same size, or only slightly smaller, than those on leading edge of scape. Apicoscrobal hair short and inconspicuous, weakly expanded apically; posterior to this the dorsolateral margin without projecting hairs except for one or two small hairs at extreme apex of occipital lobe. Cephalic dorsum with a transverse row of short suberect hairs on the occipital margin; dorsum otherwise without standing hairs. Pronotal humeral hair short-remiform; pronotal dorsum otherwise without standing hairs. Dorsum of mesonotum with 3 pairs of short stiff erect remiform hairs. First gastral tergite with stiff suberect to erect short hairs that are weakly remiform. Dorsal (outer) margins of middle and hind tibiae without suberect projecting hairs. Lamella on propodeal declivity very narrow, its posterior (free) margin shallowly concave.
Paratypes. TL 2.3, HL 0.63-0.65, HW 0.44-0.45, CI 68-71, ML 0.18, MI 28-29, SL 0.30, SI 67-68, PW 0.28-0.30, AL 0.64-0.65 (2 measured).
