Peru and

This moth, formerly Xylophanes cosmius obscurus, has been elevated to full species status as Xylophanes obscurus by Kitching and Cadiou, 2000.

Obscurus has a convex forewing median band, reaching the costa before the apex. There are no black and white checkered fringes on the forewing and basic colour is darker, more uniform and repressed than in nominate cosmius.

"Most similar to Xylophanes cosmius but outer edge of forewing entire. Forewing upperside darker, more uniform and sombre brown (Xylophanes cosmius is a greenish moth); dark patch distal to discal spot larger than in Xylophanes cosmius, trapezoidal; conspicuous postmedian line straight or slightly convex, reaching costa before the apex (in Xylophanes cosmius and Xylophanes epaphus, this line is concave and runs out to the apex); fringes not chequered."
