Oxychilus basajauna n. sp. is closely related to 0. helveticus (Blum, 1881) and 0. anjana Altonaga, 1986 but maintains constant differences: the proximal portion of the penis has a heart-shaped appearance and the inner proximal part of the penis has 30—35 very sinuous bands. This constitutes an indication that the validity of the Ortizius Forcart, 1957 subgenus should be reconsidered.
