Erythrocles is a genus of marine ray-finned fishes belonging to the family Emmelichthyidae, the rovers, bonnetmouths or rubyfishes.

The fishes in this genus are found in the western Atlantic, Pacific and Indian Oceans.

Temminck and Schlegel did not add any species to the genus they described but John Richardson added one, Emmelichthys schlegelii, in 1846.

In 1919 Jordan published his replacement name and confirmed Richardson's E. schlegelii as the type species.

[1] The genus is classified in the small family Emmelichthyidae which is included in the order Acanthuriformes.
