Abstract

MENDOZA-CIFUENTES, Humberto; AGUIRRE-SANTORO, Julián  and  IDARRAGA, Álvaro. Two new species of Miconia (Melastomataceae) from the eastern foothills of the Cordillera Central of Antioquia, Colombia. Biota colombiana [online]. 2018, vol.19, suppl.1, pp.17-28. ISSN 0124-5376.  https://doi.org/10.21068/c2018.v19s1a03.

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.

Keywords : Flora of Colombia; Miconieae; Northern Andes; Subandean Forest; Taxonomy.
