Zusammenfassung:The Cundinamarca Antpitta (Grallaria kaestneri sp. nov.) is described from a locality at upper subtropical elevations of the eastern slope of the Eastern Andes of Colombia. It is a terrestrial bird of the understory of primary and secondary cloud forest, known from elevations of ca 1800-2300 m at the type locality; its vocalizations, foraging behavior, and probable breeding season are described. The closest relative of the new form appears to be the Santa Marta Antpitta (G. bangsi) of the Santa Marta mountains; in fact, G. kaestneri may be the present-day representative of the ancestral population that gave rise to G. bangsi. The probable distribution, and possible conservation measures for G. kaestneri are discussed. /// Se describe Grallaria kaestneri sp. nov. de una localidad de la zona subtropical alta de la vertiente oriental de la Cordillera Oriental de los Andes de Colombia. Es un ave terrestre del sotobosque de selva nublada primaria y secundaria; en la localidad típica ha sido registrado entre ca 1800 y 2300 m de elevación. Se presentan datos sobre la época de cría, las vocalizaciones, y el comportamiento de forrajeo de la nueva especie, cuya pariente mas cercano parece ser G. bangsi de la Sierra Nevada de Santa Marta; incluso, kaestneri bien podría ser el representante actual de la población ancestral que dio origen a bangsi. Se discuten la distribución probable de G. kaestneri, y posibles medidas para la conservación de la especie.
