Dissections and scientific illustrations were done of the spiral organ located in the forewing subcostal vein of H. chloe, which was compared with other Hamadryas species that produce audible sound signals. Important differences were found; for example, in H. chloe, this organ is split into many independent pieces called membrane discs, whereas in the others species, it consists of just a single spiral. Implications for systematic analysis are discussed, with support from observations on ecology, chorology, and male genitalia.
