Neococytius cluentius

Neococytius is a monotypic moth genus in the family Sphingidae erected by Ronald W. Hodges in 1971. Its only species, Neococytius cluentius, the Cluentius sphinx, was first described by Pieter Cramer in 1775 as Sphinx cluentius. It is found in northern South America, Central America, Mexico and the Caribbean. It is rare on Cuba. It has been recorded in North America, from Mississippi north to Michigan and Illinois.

The wingspan is 140–160 mm. There are at least three generations in the tropics, with adults on wing from December to January, May to June (or July in Jamaica) and October.
