SPECIES Cryptotis parva

Author:Say, 1823.
Citation:In James, Account Exped. Pittsburgh to Rocky Mtns, 1: 163.
Common Name:North American Least Shrew
Type Locality:"Engineer Cantonment," west bank of Missouri River; restricted by Jones (1964:68) to USA, Nebraska, Washington Co., approximately 2 mi. (3.2 km) east Ft. Calhoun.
Distribution:Extreme SE Canada through EC and SW USA and Mexico S to Chiapas and W to Nayarit.
Status:IUCN Lower Risk (lc).
Comments:Reviewed by Whitaker (1974, Mammalian Species No. 43), who recognized 9 subspecies, 5 of which occur in Middle America (Choate, 1970). Woodman (2002) concluded that orophila is a diagnosable species; see under that name. The remaining taxa are tentatively assigned to the five subspecies noted here (Carraway, pers. comm., 2003; Woodman, pers. comm., 2002). Some of these taxa may in fact represent good species. Karyotypes from Missouri and Texas count 2n = 52, FN = 54 (Genoways et al., 1977).
