A forest genus building distinctive 'pillar-box' type mounds, roughly round in cross-section. These vary from c. 0.5 - 1 m in height, the tallest having shallow one or two constrictions along their length. The outside of the mound has an embossed lozenge pattern indicating the position of chambers beneath. Internally the structure is similar to the closely-related Cubitermes. The mounds are usually free-standing, but many are built against the sides of trees. True (Group IV) soil feeders.
