Nasutitermitinae
Nasute Termites
Nasutitermitinae is a subfamily of higher termites within Termitidae, comprising 81 genera and approximately 605 species with near-cosmopolitan distribution. The subfamily is distinguished by a highly derived soldier caste bearing vestigial mandibles and a prominent fontanellar process (the nasus) used to project chemical defenses. Notable genera include Nasutitermes, Hospitalitermes, and Constrictotermes, the latter two recognized for forming conspicuous above-ground foraging trails.
