Position cytotaxonomique de quelques musaraignes du genre Crocidura au Tessin (Mammalia, Insectivora)

The chromosome study of 14 shrews of the genus Crocidura caught in the Tessin confirms the presence of two species South of the Alps C. leucodon and C. suaveolens = C. mimula, but not C. russula. The first is caracterized by 2N = 28 and NF = 56. The new data on C. suaveolens permits the rectification of the karyotype formerly described (Meylan, 1966) and to point out a polymorphism based on the presence of supernumerary autosomes. The 2N in that species is 40, 41 and 42 with respectively a NF of 50, 52 and 54. The taxonomical situation of the Crocidura species living South of the Alps is discussed in relation to these new data.
