It is similar to Xylophanes damocrita but larger, the forewings are more elongate, making the outer margin appear almost straight, the hindwings are longer (the apex clearly exceeding the forewing tornus).
It is intermediate in forewing shape between Xylophanes damocrita and Xylophanes josephinae, but distinguishable from both by the much broader pale orange median band on the hindwing upperside.
