Notes.

Heteropterys comprises 166 currently accepted species (75 threatened species; Suppl. material 1) of treelets, shrubs, subshrubs or lianas endemic to rainforests, savannas, and seasonally dry tropical forests from North America (Mexico) to South America (Argentina), and West Africa (Angola, Cameroon, Congo, Gabon, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Senegal, Sierra Leone, and Zaire; POWO 2024). There is no updated identification key for all species of Heteropterys, but for regional treatments, see Anderson (1981) for the Guyana Highland, Almeida et al. (2020) for Brazil, and Pool (in prep.) for Mesoamerica. Glicophyllum jussieuanum (Nied.) R. F. Almeida is here placed in the synonymy of G. argenteum (A. Juss.) R. F. Almeida & M. Pell. comb. nov., due to its basionym being a replacement name for Hiraea argentea A. Juss.
