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). |
