In the imago caste, Anaorotermes is distinguished from Ateuchotermes and Aderito- termes by its dense irregular head pilosity which does not form a pelt, and from Alyscotermes, Astalotermes and Astratototermes by its oddly shaped almost triangular fontanelle. Amicotermes has longer apical mandibular teeth. It is unlikely to be confused with any other genus. In the worker caste, the enteric valve armature is so distinct and characteristic that no comparisons are 484 485 Figs 482-492.
