The Antillean piculet (Nesoctites micromegas) is a species of bird in the woodpecker family Picidae. It is monotypic within the genus Nesoctites. The species is evolutionarily distinct from the other piculets and is afforded its own subfamily Nesoctitinae. It is endemic to the Caribbean island of Hispaniola (split between the Dominican Republic and Haiti). A fossil feather in amber attributed to the genus has been found in the Dominican Republic, showing that the ancestors of the species have been isolated on Hispaniola for at least 25 million years.
