Microtus gerbei (Gerbe, 1879) . Le Naturaliste, 1:51.

TYPE LOCALITY: France, Loire-Inferieure, Dreneuf .

DISTRIBUTION: SW France, and the Pyrenees Mtns of France and Spain (see Krapp, 1982d).

SYNONYMS: brunneus , pyrenaicus .

COMMENTS: Subgenus Terricola , savii species group sensu both Chaline et al. (1988) and Zagorodnyuk (1990). This species was reviewed by Krapp (1982d) under the name pyrenaicus , but according to Spitz (1978) the latter is a nomen dubium and gerbei assumes priority. The species was included in savii by Corbet (1978c), but chromosomal evidence and craniometric analysis underscore its specific integrity ( Kratochvil and Krâl, 1974; Spitz, 1978). Chromosomal data (as pyrenaicus ) summarized by Zima and Krâl (1984a).
