Which combination of traits helps distinguish termites from ants?

Distinguishing termites from ants comes down to two easy morphological clues: the antenna shape and the waist. Termites have straight, bead-like antennae that extend in a straight line from the head, and their waists are broad rather than pinched. This means there isn’t a noticeable constriction between the thorax and abdomen. Ants, on the other hand, have elbowed (geniculate) antennae and a distinct narrow waist formed by a petiole, which creates that noticeable pinch between body segments. So, the trait combination of straight antennae and broad waists is the clearest pair that identifies termites and sets them apart from ants.
