Diagnostic characters
Soldier dimorphic (small soldier known only in M. triceratops). Major soldier head capsule evenly rounded, or with a dorsal swelling and one anterior projection on each side of the midline, the surface densely covered with microgranules; anterior part of the head narrowed into a stout conical nasus, the tip of the nasus extending far beyond the mandible apices; mandibles strongly incurved, at rest with the apices directed laterally and not upturned, each with a pointed marginal tooth at the middle; antennae 15-segmented.
