Fig. 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
