Ceratozamia, a genus of Zamiaceae, is one of the most species rich genera of gymnosperms in Mexico with a high level of species endemism. Over the last two decades, their known diversity has increased considerably because of extensive field work. Recently, 16 new species were described as a result of revision of species complexes and new explorations in southern Mexico. Here, we describe a new species from Oaxaca (Mexico) which inhabits an evergreen tropical forest. We collected this species during fieldwork in a little studied area located in the karst region of northern Oaxaca. The new species, C. martinezii sp. nov., is described and illustrated, and its phenological pattern is characterized. The species is compared with geographically close and morphologically similar species. Additionally, we present notes on the reproductive phenology of the new species and a taxonomic key for diagnosability.
