Popis:A new species of Pleurothallis subgenus Talpinaria, discovered in the department of Tolima, Central Andes of Colombia, is described, illustrated, and discussed. The new species, Pleurothallis vallejoi is compared with P. talpinaria from Colombia and Venezuela, P. trimeroglossa from Peru and Ecuador, P. jostii, presumed to occur in Ecuador, and P. gracilicolumna from Colombia. The new species is distinguished from the previous ones by a lip with subquadrate lateral lobes, with narrowly elliptical basal auricles, and a callus that is elongated, thin, and slightly elevated, with the median lobe occupying almost half of the total lip length. Additionally, the pollination mechanism of the P. talpinaria complex is described and discussed.
