Macroptatus deppens Prena new species is described from México and El Salvador. Optatus stockwelli Prena new species is described from Panamá. Optatus Pascoe, 1889 and Macroptatus Heller, 1906 are maintained as distinct genera based on the development of the prosternal process separating the procoxae. Other previously used characters on the rostrum, tarsus, and metaventrite grade together across species or are deemed species-specific. Species of these genera appear to be associated with Annona fruits.
