SPECIES Sorex (Otisorex) hoyi

Author:Baird, 1857.
Citation:Mammalia, in Repts. U.S. Expl. Surv., 8(1): 32.
Common Name:American Pygmy Shrew
Type Locality:USA, Wisconsin, Racine.
Distribution:N taiga zone of Alaska, Canada and the USA, with S outliers in the montane forests of the Appalachian and Rocky Mtns.
Status:IUCN Lower Risk (lc).
Comments:Formerly in Microsorex, which is a synonym of subgenus Otisorex, according to George (1988). Includes thompsoni since Diersing (1980b), but D. T. Stewart (in litt.) suggested that it may be a distinct species, as previously postulated by Long (1972b). Reviewed by Long (1974, Mammalian Species No. 33) and Junge and Hoffmann (1981). Sorex browni George, 1988 [replacement name for minutus (Brown, 1908), not Linnaeus, 1766] is the name for a Wisconsinan shrew related, if not conspecific, with S. hoyi. The name montanus used by Long (in Wilson and Ruff, 1999) for the Colorado and Wyoming population is a secondary homonym of S. montanus Kelaart (now Suncus montanus), and may therefore persist (Hutterer and Zaitsev, 2004). Karyotype insufficently known; Meylan (1968) provisionally identified 2n = 62, FN = 72.
