Spinifex termite Eutermes triodiae soldiers, from here.

Belongs within: Nasutitermitinae.

Eutermes has been used in the past as a cosmopolitan genus of nasute termites; its members are now divided between a number of other genera, and the name Eutermes itself is little used.

Characters (from Hill 1942): Winged adult: Head broadly oval, generally narrowed towards the front. Fontanelle usually in middle of head. Ocelli variable in position. Eyes small to large. Postclypeus variable in length from much less than half its width to more than half its width. Labrum widest in the middle. Mandibles variable, first tooth usually about as long as second, rarely much longer than second. Antennae of 13-17 segments. Pronotum very slightly saddle-shaped, narrower than head. Meso- and metanotum usually more or less widely indented posteriorly. Wing stumps almost equal in size. Wings usually dark in colour, rarely hyaline. Radius usually absent. Median vein very close to cubitus, all veins distinct, particularly the anteriormost veins and proximal branches of the cubitus. Cerci short. Styli absent. Tibiae with two apical spurs. Soldier: Nasute. Mandibles rudimentary, with molar part more or less evident, often with point towards apex. Antennae of 10-15 segments. Pronotum always saddle-shaped. Cerci present. Styli absent. Tibiae with two apical spurs. Worker: Head wide and relatively flat. Fontanelle in middle of head, more or less distinct. Postclypeus and mandibles as in winged adult. Antennae of 12-17 segments. Pronotum saddle-shaped. Cerci short. Styli absent. Tibiae with two apical spurs.
