| Summary: | 61. Masked Shrew Sorex cinereus French: Musaraigne cendrée / German: Amerikanische Maskenspitzmaus / Spanish: Musarana ceniza Other common names: Cinereus Shrew, Common Shrew Taxonomy. Sorex arcticus cinereus Kerr, 1792, Fort Severn, Ontario, Canada. Sorex cinereus is in the S. cinereus group and subgenus Otisorex. The S. cinereus group contains S. rohweri, S. longirostris, S. cinereus, S. fontinalis, S. lyelli, S. emarginatus, S. millet, S. preblei, S. hayden, S. pribilofensis, S. ugyunak, S. portenkoi, S. jacksoni, S. camtschaticus, and S. leucogaster. S. fontinalis has generally been considered a subspecies of S. cinereus but is considered a separate species here because the two species apparently overlap in distribution in Pennsylvania without interbreeding, although genetic data are needed to supportits species status. Recently, some Pacific Northwest populations have been described as a new species, S. rohweri, based on morphometric and genetic data. Sorex longipilis and S. milleri are included in S. cinereus genetically, but S. cinereus might represent multiple species. Recent genetic data have found various clades in S. cinereus from the Midwest, West, Southwest, Southeast, and East; S. longirostris being closest to the East clade; and S. milleri being closest to the Midwest clade. Sorex miller: might represent a relict population of S. cinereus, although morphometric data show that S. milleriis distinct; additional research is needed. Morphological data placed S. cinereus close to S. haydeni and S. fontinalis, although genetic data have not supported this. Two populations from south-western USA were closer to various other species, one from the central Rocky Mountains being closer to S. lyelli and the Beringian clade, while the other from northern Arizona and New Mexico was closer to S. haydeni and S. preblei. Subspecies acadicus is now considered a junior synonym of nominotypical cinereus based on recent morphometric studies. Subspecies here do not currently represent distributions of major clades in ... |
