Belongs within: Termitinae.
Contains: Eutermes, Nasutitermes, Bulbitermes.
The Nasutitermitinae, nasute termites, are a distinct group of termites in which the head capsule of the soldier caste has an enlarged frontal gland and the fontanelle placed on a protruding rostrum, allowing the ejection of defensive chemicals at threats to the colony. The development of the rostrum is correlated with the reduction of the mandibles which are usually non-functional in the soldiers. The mandibles retain sharp points in the basal genera Angularitermes and Mimeutermes (Ahmad 1950).
Members of the African genera Mimeutermes and Postsubulitermes feed on humus, presumably digesting the decomposed vegetable matter it contains. The majority of other genera feed on wood and/or leaf litter (Inward et al. 2007).
