Abstract

Se describen dos especies de Melastomataceae de frutos carnosos procedentes del departamento de Antioquia, Colombia: Miconia mailynii y Miconia hernandogarciae. Miconia mailynii se caracteriza por la presencia de mirmecófilos, hojas levemente anisófilas e inflorescencias terminales; los taxones más cercanos corresponden a especies del género Clidemia de Panamá y Costa Rica. Miconia hernandogarciae se asocia al clado Octopleura y se distingue por poseer inflorescencias terminales y hojas con venación basal. Estas dos especies se consideran endémicas al piedemonte asociado al Magdalena Medio de las cordilleras Central y Oriental de Colombia y, debido a su distribución restringida y especificidad de hábitat, se recomienda su categorización como En peligro (EN). Miconia mailynii and Miconia hernandogarciae, two new species of berry-fruited Melastomataceae from the department of Antioquia, Colombia, are described. Miconia mailynii is characterized by the presence of ant domatia, slightly anisophyllous leaves, and terminal inflorescences. This species is probably related to those species previously placed in the genus Clidemia from Panama and Costa Rica. Miconia hernandogarciae is associated within the clade Octopleura, and can be distinguished by its terminal inflorescences and leaves with basal venation. These two species are endemic to the foothills of the Cordillera Central and Cordillera Oriental around the central Magdalena Valley of Colombia. Because of their restricted distribution and habitat specificity, the categorization of species these species as Endangered (EN) is recommended.
