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

Left mandible index 0.68 (alate); soldier dimorphic — in all the remaining genera of the Subulitermes branch the soldier is monotypic; soldier mandibles without apical points.

Alate

Head and pronotum densely covered with setae and short hairs; abdominal tergites with short hairs and a few setae at the sides, nearly forming a marginal row; fontanelle distinctly forked anteriorly; postclypeus length much greater than half its width (length 0.22 mm, width 0.32 mm); 2nd marginal tooth of the right mandible prominent, the cutting edge of the 1+2 marginal teeth of the left mandible long, the left mandible apical tooth relatively long; left mandible index 0.68; the sides of the pronotum flattened and rounded, not drawn back posteriorly as in Australitermes and Macrosubulitermes; meso- and metanota each with a broad shallow depression; tibial spur formula 2:2:2.

Dimorphic; mandibles without apical points.
