Mayriella transfuga

Identification
This taxon can be separated from other species in the genus by the presence of well developed sculpturing in the posterior section of the scrobe, the large, closely spaced pits on the mesosomal dorsum, the parallel lateral surfaces of the postpetiole, the strongly angular petiolar node and the relatively long propodeal spines (length greater than 1.5 times the width of their bases). It is most similar to Mayriella granulata but can be separated based on the longer and narrower propodeal spines. (Shattuck and Barnett 2007)

Worker
Shattuck and Barnett (2007) - Sculpturing in posterior section of antennal scrobe well developed and distinct; sculpturing on dorsal surface of mesosoma consisting of large, closely spaced pits; propodeal spines relatively long and thin; dorsal surface of petiole in lateral profile uniformly convex, without distinct dorsal and posterior faces and forming a sharp angle with the anterior face; in dorsal view, postpetiole with the anterior and posterior regions approximately the same width (the region connecting them either flat or weakly convex); postpetiole and gaster lacking erect hairs dorsally.
