Calyptomyrmex is a genus of slow moving armored ant. Calyptomyrmex is monomorphic and monogynous. This mid size ant measure at slightly over 4 millimeters.There is a recess on both sides of the head behind the antennae that allow this armoured ant to withdraw their antennae similar to Cephalotes turtle ants but Calyptomyrmex lack spines (thorns). Calyptomyrmex are subterranean ants whereas Cephalotes and Cataulacus are arboreal ants.

  1. These ants seem to have similar habits with Meranoplus. Do they have chemical defense as well?

    However, the appearence reminds me of Cephalotes turtle ants. For all I know, they might be related.

  2. Most Calyptomyrmex species do not have eyes or spines (thorns). Cataulacus is probably more closer to Cephalotes, Meranoplus too.
