A new report of Lepanthes (Orchidaceae) for Mexico and clarification of the taxonomic status of Lepanthes quetzalensis

The Neotropical genus Lepanthes is one of the largest groups within Orchidaceae. Here the presence of Lepanthes fratercula is reported by the first time for the Mexican flora. In addition, the taxonomic status of L. quetzalensis is clarified here, considering it as a different specie from L. scopula, in which it has been included as its synonym. Both L. fratercula and L. quetzalensis are described from Mexican specimens collected in Chiapas State. For each taxon information about its distribution, habitat, phenology, and conservation status in Mexico is provided. Additionally, both species are compared with other morphologically similar taxa from Central America. The richness of Lepanthes in the Mexican flora increases to 65 species, 35 of which are native to Chiapas. (C) 2017 Universidad Nacional Autonoma de Mexico, Instituto de Biologia.
