An annotated conspectus of 124 species is presented for Myrcia DC. sect. Aulomyrcia (O. Berg) Griseb. This list is published for use as a basis for future revisionary work and presents the species of this evolutionary group together for the first time. Publication and type information, habitat and distribution, preliminary conservation assessments, and diagnostic notes are provided for each species.
