A critical taxonomic and nomenclatural review of the Brazilian species of Acalypha (Euphorbiaceae, Acalyphoideae) is presented. As a result, 40 species (44 taxa including six subspecies) are accepted, 37 of them native (17 endemic) and three introduced; also, 132 names are considered synonyms, 28 of them for the first time. Two new combinations are proposed: Acalypha brasiliensis subsp. asterotricha and A. brasiliensis subsp. psilophylla, previously considered varieties of A. brasiliensis. Information about types is provided for all the valid names, and 54 lectotypes and one neotype are designated. Identification keys and detailed distribution maps of all the native taxa are also provided.

In 1865, Müller Argoviensis proposed Acalypha fallax based on specimens from Peninsula Indiae orientalis, which is now considered synonymous with A. lanceolata Willd. A recent study conducted in Tamil Nadu, India, from 2019 to 2022 thoroughly examined Acalypha species using multiple criteria: leaf epidermal characteristics, seed morphology, pollen features observed via scanning electron microscopy (SEM), and sequencing of the ITS, rbcL and matK spacer regions. This work identified distinctions between A. fallax and A. lanceolata, such as longer peduncles, obovate bracts in male flowers, and stems with two types of trichomes: strigose and hirsute. Moreover, the study proposed a new species, A. brittoi, which is described here as distinguishable from A. fallax by its larger leaf blades with 13–14‐toothed margins (compared to smaller blades with 8–9‐toothed margins in A. fallax), and by the ovate perianth of its male flowers (versus orbicular perianth in A. fallax). Unique patterns of leaf epidermal crystals and granules on seed surfaces further aided in distinguishing A. fallax from A. brittoi. Molecular analysis additionally confirmed genetic differences among these three species.
