Two new distribution records for species of Bruchinae (Coleoptera: Chrysomelidae) from the Galapagos Islands are reported and discussed: Acanthoscelides machala (Johnson, 1990), and Acanthoscelides macrophthalmus (Schaeffer, 1907). We also report two new host plant associations: A. machala in Senna obtusifolia (L.) H.S. Irwin & Barneby (Fabaceae), and Scutobruchus ceratioborus (Philippi, 1859) in Leucaena trichodes (Jacq.) Benth. (Fabaceae). Finally, we provide a revised checklist of Bruchinae species in the Galapagos and their associated host plants.
