Etymology
From Greek allos (other) + gnathos (jaw) + Latin termes.
The etymologies in this section are analytical breakdowns; the roots follow Brown (1956).
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
Closely related to Hoplognathotermes and Duplidentitermes. The mandibular teeth of the soldier are less conspicuous than in those two, but the left mandible has 2 rather widely separated teeth, apparently homologous with the bidentate teeth of Duplidentitermes; the fore coxal ridge is very similar to that of Duplidentitermes, only slightly more evident because it extends with a slight inward curve; the fore femur is short and stout, as in Duplidentitermes, and clearly different from the slender fore femur of Firmitermes, Hoplognathotermes and Acutidentitermes. The second marginal tooth of the right mandible of the alate is reduced to a small mound.
Alate
The second marginal tooth of the right mandible is reduced to a small mound, as in Duplidentitermes.
Soldier
The mandibular teeth are less conspicuous than in Hoplognathotermes and Duplidentitermes, but the left mandible has 2 rather widely separated teeth, apparently homologous with the bidentate teeth of the left mandible of Duplidentitermes. The longitudinal ridge of the fore coxa is very similar to that of Duplidentitermes, only slightly more evident owing to a slightly curved inward extension. The fore femur is short and stout, as in Duplidentitermes, whereas in Firmitermes, Hoplognathotermes and Acutidentitermes it is slender.
