M. rettenmeyeri, named after entomologist Carl Rettenmeyer, has an unusual longitudinal band of black hairs extending along the midline of the cephalothorax, enhancing its resemblance to Camponotus sericeiventris, an ant it shares a habitat with. The black hairs correspond to the solid longitudinal keel-like dorsal extensions of the posterior sections of the ant's thorax.
