Etymology
From Latin diversus (diverse) + 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
The most conspicuous feature is the trimorphism of the soldier: in the major soldier the nasus is narrow and slender with a weak basal depression; in the medium and minor soldiers the head capsule is more or less dumbbell-shaped constricted; antennae 13-segmented; the legs of the two small soldier types are rather long. In the same group Velocitermes is dimorphic (corresponding to the medium and minor types of this genus) and Trinervitermes is dimorphic or rarely trimorphic but has no apical part on the mandibles; the three fixed soldier types remain the most conspicuous mark of this genus. The alate is distinguished from Rotunditermes (eyes very large) by the medium-sized eyes, the 1st marginal tooth of the mandible about as long as the 2nd, and the clypeus about as long as half its width.
Alate
Compound eyes medium-sized (the original key contrasts them with the very large eyes of Rotunditermes, and that branch additionally records the compound eyes as bulging dorsolaterally on the head and the pronotum as relatively large); the 1st marginal tooth of the mandible about as long as the 2nd; clypeus about as long as half its width, or slightly shorter and strongly convex, transversely oval, pale yellow and sometimes dark; antennal segments with average elongation.
Soldier
Soldier trimorphic. Major soldier: nasus narrow, basal depression weak. Medium and minor soldiers: head capsule more or less markedly dumbbell-shaped constricted; antennae 13-segmented. The legs of the two small soldier types are rather long.
