Xylophanes macasensis is a moth of the family Sphingidae. It is found from Ecuador south into Bolivia. The wingspan is about 80 mm for both males and females. It is similar to Xylophanes ockendeni, but larger and with many pattern differences. Furthermore, the small black spots on the dorsum of the abdomen are somewhat larger. The underside of the abdomen is brown or brownish-white.

The submarginal line of the vein spots is connected by a series of darker green lunate mar
