Microtus multiplex (Fatio, 1905) . Arch. Sci. Phys. Nat. Geneve, Ser. 4, 19:193.

TYPE LOCALITY: Switzerland, Ticino Canton, near Lugano .

DISTRIBUTION: S Alps and N Apennines in Switzerland, Austria, Italy, and France; also NW and C Yugoslavia (see map in Krapp, 1982b).

SYNONYMS: fatoi, druentius, leponticus, liechtensteini, orientalis, petrovi.

COMMENTS: Subgenus Terricola . Placed in subterraneus species group by Chaline et al. (1988) but in the multiplex group, along with M. tatricus, by Zagorodnyuk (1990). Reviewed by Krapp (1982b). Corbet (1978c, and references therein) viewed liechtensteini as a separate species, but Krapp (1982b) included it in M. multiplex . Two distinctive karyotypes exist, one with 2N=48 ( multiplex) and the other with 2N=46 ( liechtensteini), but there is a record of hybridization (Zima and Krâl, 1984a). Tarsal glands compared (as liechtensteini) with those of M. subterraneus by Hrabe (1977).
