Archaeoprepona demophon, the one-spotted prepona, banded king shoemaker, or demophon shoemaker^[1] is a butterfly belonging to the family Nymphalidae.

The wingspan reaches about 54–58 millimetres (2.1–2.3 in). The uppersides of the wings are black, with bright pale blue transverse bands. The undersides are pale brown with a clearer band in the middle of the hindwings and several dark small dots on the margins.

The butterfly larva generally feed on plants of the genus Annona (Annonaceae) and on Malpighia glabra (Malpighiaceae). Adults visit rotten fruit or dung.

This species can be found in Mexico, Central America, the West Indies, and northern portions of South America.

Archaeoprepona demophon prefers the edges of forest canopy and subcanopy.
