Revalidation of the genera Bia and Zuckertia (Euphorbiaceae) with B. capivarensis sp. nov. from Serra da Capivara, Brazil

Researchers revalidate the genera Bia and Zuckertia, previously considered sections of Tragia, based on morphological and molecular analyses. The study proposes a new circumscription for Bia and describes B. capivarensis sp. nov., a newly discovered species from Serra da Capivara National Park, Brazil. This discovery contributes to the taxonomic understanding of Euphorbiaceae and highlights the biodiversity significance of the region. The research also provides a key to distinguish between Zuckertia and Bia, along with detailed morphological data for the new species.
