Ants in the genus Mesostruma are uncommon and form small colonies in soil, usually under or between rocks. They are predacious, foraging primarily on the ground in leaf litter but also occasionally on low vegetation. Roughly half the species have only been collected once. The remainder of the species are not well known either, at least in terms of the number of collections and what is known regarding their biology.
The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

Taylor (1991) reported on a specimen collected from Geraldton, Western Australia which he placed in an undescribed taxon, Mesostruma sp. no. 1 (ANIC). This specimen compares well with the types of M. loweryi and it is here considered to belong to this species. It should be noted that the collection site of this specimen and the only other known site of this species, the type locality, are separated by some 2300 km, the former being from western Western Australia and the latter from south-eastern South Australia. While this might suggest that these specimens are not conspecific, a similar distribution pattern is known for M. eccentrica, giving support to the proposed placement. (Shattuck 2000)
Shattuck (2000) - TL 3.6, HL 0.82 - 0.83, HW 0.71 - 0.72, CI 87, ML 0.31 - 0.32, MI 38 - 39, SL 0.47 - 0.49, SI 66 - 68, PW 0.47 - 0.48, AL 0.90 - 0.91 (2 measured). Head relatively narrow (CI < 88). In dorsal view the anterolateral corners of pronotum rounded. Dorsum of mesosoma with scattered, shallow foveolate punctures which are spaced more than their width apart, and with the area between the punctures smooth and lacking sculpturing. Propodeal lamellae with the dorsal and posterior margins flat, the angles between these margins approximately 90 degrees. Sculpturing on the metaplerual gland bulb consisting of weak rugae over a punctate background. Lateral surfaces of postpetiole with well developed wings. First gastral segment immediately posterior of the postpetiole with short, ill-defined rugae. Body colour yellow-red with light infuscation on the dorsum of the head, lateral mesonotum and on the first gastral tergite.
