Morphology
The description below is paraphrased from the original or a later revision, by caste; the source is cited at the end.
Diagnostic characters
The soldier is monotypic; it resembles the major soldier of Ngauratermes in size, colour, shape of the head capsule, 13-segmented antennae and the distinct tooth-like projection of the mandibles, and occurs in the same region.
Soldier
Monotypic; the nasus is more conical; the legs and antennae are longer; short hairs on the head capsule are sparse.
Worker
The mixed segment is relatively long; the Malpighian tubules are attached in a group at a single point; the end of P1 forms a short loop on the dorsal side; the spines of the two rings of the enteric valve are of similar length.
This genus is monotypic, containing only this species; the following is the genus-level description based on the original literature; species-level measurements and intraspecific variation are given in the original.
