A row of bristles arranged like the teeth of a comb on the forelegs of male Drosophila. Toward the end of the courtship ritual (q.v.) the male drums these tibial bristles on the dorsal surface of the female's abdomen. Sex combs play a crucial role in determining acceptance or rejection by the female during courtship.
