Se describe una nueva especie de Anopheles de las alturas de la Cordillera Oriental de Colombia (2700 a 2840 m. sobre el nivel del mar) muy cerca de Bogotá; del estudio se deduce que pertenece al subgénero Arthuromyia, del cual representa la tercera especie conocida. Se hace la diagnosis comparativa entre larva, pupa e hipopigio de A. vargasi, A. gilesi y A. oiketorakras n. sp., y se anotan algunos datos ecológicos, relacionados con esta especie. / Abstract.  A new species of Anopheles from a high altitude in the Eastern Andes of Colombia (2700 to 2840 m. above sea level), very near Bogota, is described. From the characters of the male terminalia, larva and pupa, the species must be included in the subgenus Arthuromyia of which it represents the third known species.  A comparative diagnosis is made between larva, pupa and hypopygium of A. vargasi, A. gilesi and A. oiketorakras n. sp. A few ecological details are given in relation to the present species.
