Morphology

The descriptions below are an adaptation of the original genus-level accounts; terms follow the meaning of the source, and the original is not transcribed verbatim.

Diagnostic characters

The nasus of the soldier is very large relative to the head, the most developed nasus known to Emerson among nasute soldier termites; the mandibles have long apical points, the base of the left mandible bears a very small microscopic tooth, and the base of the right mandible is toothless. In the alate the posterior margin of the head is angular behind the eyes in dorsal view.
