          Abstract

          We present the G-band karyotype of Sorex granarius (Miller, 1910). With minor exceptions, each of the acrocentric autosomes in this karyotype is completely homologous to one of the chromosome arms in the karyotype of the common shrew (Sorex araneus L., 1758). If, as is the simplest interpretation, the karyotypic evolution in S. araneus is by repeated Robertsonian fusion, the karyotype in S. granarius represents the ancestral condition. We urge breeding studies to establish whether the designation of S. granarius as a full species is justified.
