Paris, Ser. 3, 7:44 . TYPE LOCALITY: Portugal . DISTRIBUTION: Portugal , NW Spain, and SW France (see Niethammer, 1982/). SYNONYMS: depressus , gerritmilleri, hurdanensis, marine, pelandonius , planiceps . COMMENTS: Subgenus Terricola , duodecimcostatus species group sensu Chaline et al. (1988) . Spitz (1978) provided craniometric analyses in context of contrasting M. lusitanicus with M. duodecimcostatus and M. gerbei . Reviewed by Niethammer (1982;) and Corbet (1984) ; chromosomal data reviewed by Zima and Krâl (1984a) . Both Graf (1982) and Chaline and Graf (1988) apparently used mariae for this species, which reflects Winking's (1976) usage in separating the latter from M. duodecimcostatus ; however, the proper name is lusitanicus (Niethammer (1982;).
