Morphology
Castro et al. (2016) described a stridulatory structure in this species. They used SEM photographs to discern the details they reported.

A pars stridens much wider than long (width 0.11 mm and length 0.06 mm). This is the species with the thinnest striation in the morphometric study, together with Messor capitatus, Pheidole pallidula and Tetramorium caespitum, with an average ridge width of 0.80 μm. The outline of the pars stridens is clearly rounded. Pillars are very strong and the number of teeth on their surface is higher than in Goniomma blanci. A geometric pattern can be observed on the base of the pillars.
