Asellus (Asellus) monticola monticola Birstein, 1932 has been found in a spring in the extreme NW of Iran. Amplifications of the original description of this valid species, which is clearly distinct from A. aquaticus, are given. Contrary to A. aquaticus, A. monticola appears to be strongly endemic and stenotopic; its settlement may have taken place prior to the expansion of A. aquaticus across Europe. Some reflections on the taxonomy and biogeography of the Asellidae of the Transcaucasian region are included.
