Abstract
Quaestus (Speogeus) littoralis n. sp. from Sierra del Sueve is described. T he main distinguishing characters of the new species are the shape of the m esosternal carina and the aedeagus. The affinity with close species and the position within the subgenus Speogeus are discussed. Finally, the possible colonization of the karstic area of Sierra del Sueve and the evolutionary process of the four Leptodirinae species found in the western Cantabric reg ion are analysed.
