| description | Background and Aims: Dahlia is a characteristic genus of Asteraceae tribe Coreopsideae and eight species were known in Nueva Galicia. The objective of the present communication is to report two additional species.Methods: Botanical explorations were carried out in Nueva Galicia. Additionally, Dahlia specimens deposited at the herbaria ANSM, BUAP, CFNL, CHAPA, CIIDIR, ENCB, FCME, IBUG, IEB, MEXU, QMEX, SLPM, UAT, UAZ and XAL were reviewed and identified. Morphological descriptions and an identification key were made based on the analysis of specialized literature, revision of herbaria specimens and plants in the field. A database was compiled with the information and was analyzed with a geographic information system for the elaboration of distribution maps and proposals for protection categories.Key results: We documented Dahlia merckii and D. rupicola in Nueva Galicia. These new records extend the distribution area for both species to western Mexico. According to the categories and criteria of the International Union for Conservation of Nature, D. merckii can be qualified as a Least Concern species. Meanwhile, D. rupicola could be considered as Endangered if the area of occupation and the extension of occurrence are taken into account.Conclusions: This information extends the adaptive amplitude of both Dahlia species to habitats with different ecological conditions to those previously documented. We recommend carrying out studies to evaluate the conservation status of all the species in the genus according to conservation categories at national and international scales. Finally, the expanded distributions of D. merckii and D. rupicola indicate the need to continue and promote botanical exploration in Mexico. |

Antecedentes y Objetivos: Dahlia es un género característico de Asteraceae tribu Coreopsideae y para la Nueva Galicia se conocían ocho especies. El presente texto tiene como finalidad reportar dos especies adicionales.Métodos: Exploraciones botánicas en Nueva Galicia fueron llevadas a cabo. Se revisaron y determinaron ejemplares depositados en los herbarios ANSM, BUAP, CFNL, CHAPA, CIIDIR, ENCB, FCME, IBUG, IEB, MEXU, QMEX, SLPM, UAT, UAZ y XAL. Se realizaron descripciones morfológicas ampliadas y una clave de identificación a partir de la consulta de literatura especializada, del análisis de ejemplares de herbario y la revisión de plantas en el campo. La información recopilada se analizó con un sistema de información geográfica para la elaboración de mapas de distribución y propuestas para categorías de protección.Resultados clave: Se documenta a Dahlia merckii y D. rupicola para la Nueva Galicia. Estos nuevos registros extienden el área de distribución para ambas especies al occidente de México. De acuerdo a las categorías y criterios de la Unión Internacional para la Conservación de la Naturaleza, D. merckii se puede tratar como una especie en Preocupación Menor. Dahlia rupicola podría considerarse En Peligro tomando en cuenta los valores de extensión de la ocurrencia y el área de ocupación.Conclusiones: Estos datos extienden la amplitud adaptativa de las dos especies de Dahlia a hábitats con condiciones ecológicas diferentes a las antes reconocidas. Recomendamos la realización de estudios para evaluar el estado de conservación de la totalidad de especies del género, de acuerdo a las categorías de conservación a nivel nacional e internacional. Por último, la ampliación de las distribuciones de D. merckii y D. rupicola también señala la necesidad de continuar e impulsar la exploración botánica en México.
