Habitus: Upperside of body and wings green, often very bright. Underside of body whitish green. Forewing with three narrow antemedial lines present; postmedial line well-marked, straight, basal edge sharply delineated, distal edge diffuse, gradually lightening toward outer margin; remaining postmedial lines poorly defined or absent; oblique apical line short, often not reaching M1. Oblique apical line on forewing underside forming an angle with the irregularly undulate postmedial line below M2, the marginal area bordered by these lines as broad as in Xylophanes schausi. Hindwing green median band not reaching the costa; distal margin often green, whence the submarginal black band is reduced.
