M. rogerblancoi shares with M. oviedoi and M. rugonasus the following combination of characters: mandible strongly twisted, occipital carina complete, notauli not distinct, tarsal claw with large lobe, dorsopes absent and short ovipositor. M. rogerblancoi can be separated from M. rugonasus by having propleuron rugulose, and by having T2–T3 white medially, but this color is very different from the white elongate-oval spot on the T2 present in M. rugonasus .
