| contents | A new species of Annonaceae, endemic to the limestone karst forests of Chiapas, Mexico Gaspar Moreno-Méndez Andrés Ernesto Ortiz-Rodriguez Biología Miliuseae Cauliflory Neotropics tropical rainforest Background and Aims: In Mexico, the Neotropical genera of Annonaceae tribe Miliuseae, including Sapranthus, Stenanona and the Mexican endemic genus Tridimeris, are particularly diverse and many of their species are endemic to this country. This diversity is not fully documented and many new species have been discovered as a result of recent botanical explorations in southern Mexico. Here, we describe a new species of Stenanona. Methods: We collected a new species of Stenanona during field work in a little known karst forest area located in the highlands of Chiapas, Mexico. The new species was recognized using the unique combination of features through comparisons with morphologically similar species and literature review. We assessed its conservation status by calculating its extent of occurrence (EOO) and its area of occupancy (AOO) using the GeoCAT tool and applying the IUCN Red List Categories and criteria. Key results: A new species of Annonaceae, namely Stenanona morenoi, endemic to karstic forests of southern Mexico, is described and illustrated. According to the criteria established by the IUCN, it is possible to tentatively determine the species as Critically Endangered (CR B1ab (iii)). Conclusions: Based on its general floral morphology, S. morenoi is hypothesized to belong to subclade A of the Desmopsis-Stenanona clade. Within this lineage, S. morenoi shares several morphological features with S. migueliana, S. stenopetala and S. zoque. 2020 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57466093039 https://www.redalyc.org/journal/574/57466093039/ https://www.redalyc.org/journal/574/57466093039/html/ https://www.redalyc.org/journal/574/57466093039/57466093039.epub https://www.redalyc.org/journal/574/57466093039/movil 10.21829/abm127.2020.1625 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
