Malpighiaceae has undergone unprecedented changes in its traditional classification in the past two decades due to several phylogenetic studies shedding light on the non-monophyly of all subfamilies and most tribes and genera. Even though morphological characters were used to reconstruct the last molecular generic phylogeny of Malpighiaceae, a new classification system has never been proposed for this family. Based on a comprehensive review of the last twenty years of published studies in this family, we are proposing a new classification system and providing a taxonomic synopsis for Malpighiaceae based on molecular phylogenetics, morphology, palynology, and cytogenetics as a baseline for systematics and taxonomy of this family. Malpighiaceae currently comprises two subfamilies (Byrsonimoideae and Malpighioideae), 12 tribes Acmanthereae, Acridocarpeae trib. nov., Barnebyeae trib. nov., Bunchosieae trib. nov., Byrsonimeae, Galphimieae, Gaudichaudieae, Hiptageae, Hiraeeae, Malpighieae, Mcvaughieae trib. nov., and Ptilochaeteae trib. nov.), 71 genera (Acmanthera, Acridocarpus, Adelphia, Alicia, Amorimia, Aspicarpa, Aspidopterys, Banisteriopsis, Barnebya, Blepharandra, Brachylophon, Bronwenia, Bunchosia, Burdachia, Byrsonima, Calcicola, Callaeum, Camarea, Carolus, Caucanthus, Christianella, Coleostachys, Cottsia, Diacidia, Diaspis, Dicella, Digoniopterys, Dinemandra, Diplopterys, Echinopterys, Ectopopterys, Excentradenia, Flabellaria, Flabellariopsis, Galphimia, an undescribed genus, Glandonia, Glicophyllum, Heladena, Heteropterys, Hiptage, Hiraea, Janusia, Jubelina, Lasiocarpus, Lophanthera, Lophopterys, Madagasikaria, Malpighia, Malpighiodes, Mamedea gen. nov., Mascagnia, Mcvaughia, Mezia, Microsteira, Mionandra, Niedenzuella, Peixotoa, Philgamia, Psychopterys, Pterandra, Ptilochaeta, Rhynchophora, Schwannia, Sphedamnocarpus, Stigmaphyllon, Tetrapterys, Thryallis, Triaspis, Tricomaria, Tristellateia, and Verrucularina), and 1,483 species accepted. We provide diagnoses for all subfamilies and tribes, alongside identification keys up to genus, the necessary new combinations, and nomenclatural, taxonomic, distributional, and ecological notes up to genus. Morphological plates are also provided to illustrate the immense diversity of morphological traits used in the new classification and synopsis.
