Enyo boisduvali is a moth of the family Sphingidae. It is known from Cuba. It is similar to Enyo lugubris lugubris, but can be distinguished by the well-developed, strongly dentate postmedian lines on the undersides of both wings. Furthermore, the centre of the thorax is paler grey than the tegulae and it contains a dark brown or black median inverted Y-shaped mark. The postmedian area of the forewing upperside is dark with orange highlights. There are three well-developed transverse postmedian lines on both the forewing and hindwing underside.
