Microkayla De la Riva, Chaparro, Castroviejo-Fisher, and Padial, 2017
25 species
Common Names
None noted.
Distribution
Cloud forests, elfin forests and humid puna of the Amazonian versant of the Cordillera Oriental of the Andes, from the eastern part of Cordillera of Carabaya (Department of Puno) in southern Peru to the western limits of Department Santa Cruz in central Bolivia (Serranía Siberia, on the boundaries of Carrasco National Park, Department of Cochabamba; and Amboró National Park, Department of Santa Cruz), between 2466 and ca. 4000 m elevation, encompassing a straight line distance of ca. 670 km.
Comment
Portik, Streicher, and Wiens, 2023, Mol. Phylogenet. Evol., 188 (107907): 52, 67, suggested that the placement of Microkayla guillei as the sister taxon of part of their Noblella + Psychrophynella, might render Microkayla nonmonophyletic but recommended no taxonomic change due to weak support for this topology.
