| description | Background and Aims: The genus Agave comprises 159 species and is the eighth most diverse of the Mexican flora. In this work four new species for science are described, result of the exploration of little-known areas from a botanical point of view in the south of Mexico.Methods: As a result of field and herbarium work in the states of Guerrero, Oaxaca, and Puebla, populations of agaves were found whose morphological characteristics do not correspond to previously described species. Following a morphological analysis and a literature review, these are formally described. The conservation status of the four species was evaluated based on the criteria of the NOM-059-SEMARNAT-2010 and the method proposed by the International Union for the Conservation of Nature.Key results: The new species are described and illustrated here, Agave lyobaa, from the subgenus Agave group Ditepalae, and three from the subgenus Littaea, A. gypsicola from the Choritepalae group, and A. quiotepecensis and A. megalodonta from the Marginatae group. For each one, information is provided on distribution, habitat, phenology, possible morphological relationships with other species of the genus, and uses. According to the criteria of the NOM-059-SEMARNAT-2010, the four species are proposed in the Threatened category (A). Based on the method proposed by the IUCN, the first two species are placed in the category Endangered (EN) and the last two in the category Near Threatened (NT).Conclusions: The four species of Agave described here are endemic to Mexico and distributed in the states of Guerrero, Oaxaca, and Puebla. Each is composed of vulnerable populations that require priority conservation actions. |

Antecedentes y Objetivos: El género Agave está conformado por 159 especies, es el octavo más diverso de la flora mexicana. En este trabajo se describen cuatro especies nuevas para la ciencia, resultado de la exploración de áreas poco conocidas desde un punto de vista botánico en el sur de México.Métodos: Como resultado de trabajo de campo y de herbario en los estados de Guerrero, Oaxaca y Puebla, se encontraron poblaciones de agaves cuyas características morfológicas no corresponden con especies descritas con anterioridad, por lo que después de un análisis morfológico y una revisión bibliográfica se describen formalmente. El estado de conservación se evaluó con base en los criterios de la NOM-059-SEMARNAT-2010 y el método propuesto por la Unión Internacional para la Conservación de la Naturaleza.Resultados clave: Se describen e ilustran Agave lyobaa, del subgénero Agave grupo Ditepalae, y tres especies del subgénero Littaea, A. gypsicola del grupo Choritepalae y A. quiotepecensis y A. megalodonta del grupo Marginatae. Para cada una se proporciona información sobre su distribución, hábitat, fenología, posibles relaciones morfológicas con otras especies del género y usos. Según los criterios de la NOM-059-SEMARNAT-2010, las cuatro especies se proponen en la categoría amenazada (A). De acuerdo con el método propuesto por la IUCN, las dos primeras especies se encuentran en la categoría En Peligro (EN) y las dos últimas como Casi Amenazada (NT).Conclusiones: Se describen cuatro especies endémicas de México, distribuidas en los estados de Guerrero, Oaxaca y Puebla; todas ellas con poblaciones vulnerables que requieren acciones prioritarias de conservación.
