Summary
Figure 6. Morphological characteristics of the mesosoma and gaster of Brachymyrmex. (a1) metathoracic spiracles tumiliform; (a2) metathoracic spiracles not protruding; (a3) metathoracic spiracles slightly protruding, but not tumiliform; (b1) mesonotum inflated and bulging dorsally above the pronotum in lateral view; (b2) mesonotum not inflated or bulging dorsally above the pronotum in lateral view; (c) dorsal margin of the mesosoma of conspicuous sinusoidal shape; (d1) mesometanotal suture inconspicuous (dashed line); (d2) mesometanotal suture directly visible; (e1) mesonotum strongly antero-posteriorly inclined and thus elongated in lateral view; (e2) mesonotum weakly antero-posteriorly inclined in lateral view; (f1) metanotal groove deep and wider than the diameter of the metathoracic spiracles; (f2) metanotal groove shallow and narrower than the diameter of the metathoracic spiracles; (g1) gaster with scattered pubescence; (g2) gaster with dense pubescence, in both cases illustrated with long erect hairs near the edges of the segments; (h1) mesonotum laterally extended and oval in dorsal view; (h2) mesonotum almost circular in dorsal view.
