Cautethia exuma is a species of moth in the family Sphingidae, which is known from the Bahamas.

[1][2] Moths in this species have a wingspan of 27–32 millimetres.

They are immediately distinguishable from all other Cautethia species by the pale yellow-brown basal area of the hindwing upperside.

The larvae probably feed on Rubiaceae species.
