The new genus Macrosaccus Davis & De Prins is proposed for three species formerly assigned to the genus Phyllonorycter: M. robiniella (Clemens), M. morrisella (Fitch), and M. uhlerella (Fitch); two new, closely related species: M. neomexicanus Davis and M. gliricidius Davis, are also proposed. Descriptions of the adults, pupae, larvae, life histories, and distributions are supplemented with photographs, line drawings, and scanning electron micrographs. Larvae of all species are serpentine/blotch leaf miners on various genera of the plant family Fabaceae. The genus is endemic to the New World, with the invasive species M. robiniella now widely established in Europe.
