The genus was erected by William John Swainson in 1829.
In older literature, all three species were placed in the genus Diorina Morisse 1838 currently viewed as a subjective junior synonym, the older name having priority.
Rhetus periander often features in butterfly wall displays.
Subspecies
There are three species:[1]
- Rhetus arcius (Linnaeus, 1763) – paler than R. periander and with longer thinner tails
- Rhetus dysonii (Saunders, 1850) – outer margins of the forewings convex, distinct white bands, and white markings on the tail
- Rhetus periander (Cramer, [1777]) – commonest and most widespread
