Xylophanes schreiteri is a moth of the family Sphingidae.

Furthermore, distal to discal spot on the forewing upperside there is a dark brown dash running parallel and sometimes connected to the first postmedian line, which is stronger and reaches closer to the apex.

The forewing underside has a pale yellow apical area on the costa, although this is occasionally pale buff and contrasting strongly with the orange-yellow ground colour.

Adults are on wing from February to March and again from October to November in Argentina.

The larvae probably feed on Rubiaceae and Malvaceae species.
