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 soldier mandibles lack apical points; in the worker (nymph) the 1+2 marginal tooth of the left mandible is exceptionally long, the left mandible index is 0.62, and the third marginal tooth is distinctly smaller than in Leucopitermes; the outline of the molar plate of the right mandible is concave; the angle between the apical tooth and the first marginal tooth of both mandibles is wider than in any related genus of the Oriental region.
Soldier
Mandibles without apical points.
Worker
The original describes a worker–nymph: the 1+2 marginal tooth of the left mandible is exceptionally long; the left mandible index is 0.62; the third marginal tooth is distinctly smaller than in Leucopitermes; the outline of the molar plate of the right mandible is concave; the angle between the apical tooth and the first marginal tooth of both mandibles is wider than in any related genus of the Oriental region.
