Map showing the distribution of Neomys anomalus anomalus, N. a. milleri and N. teres. The original distributions were downloaded from the IUCN Red List of Threatened Species website [72, 73] and they were modified to reflect the results of our genetic analyses. Dots indicate samples used for sequencing nuclear introns and cytochrome b (large dots) or only cytochrome b (small dots). The locations of additional cytochrome b sequences downloaded from databases are indicated with diamonds (with empty diamonds corresponding to samples being used in the cytochrome b tree but not in the species tree analyses). All localities correspond to a single specimen, except the localities of N. teres. Locality numbers are given in Tables S1 (for samples obtained for this work) and S2 (for database sequences) of Additional file 1. Type localities of N. a. anomalus (San Martín de la Vega, Madrid, Spain) and N. a. milleri (Chesières, Alpes Vaudoises, Switzerland) are indicated with a star symbol. The distribution of N. fodiens largely overlaps with that of the other species and it is not shown here; see Additional file 1: Tables S1 and S2 for further details
