SPECIES Thomomys (Megascapheus) townsendii
| Author: | Bachman, 1839. | | Citation: | J. Acad. Nat. Sci., Philadelphia, 8: 105. | | Common Name: | Townsend’s Pocket Gopher. | | Type Locality: | USA, erroneously given as "Columbia River", but restricted to Idaho, Canyon Co., near Nampa, by Bailey (1915). | | Distribution: | Snake River Valley of Idaho south and west to SE Oregon, NE California, and N Nevada (USA). | | Status: | IUCN – Lower Risk (lc). | | Comments: | Subgenus Megascapheus. Revised by Davis (1937) and Rogers (1991a, b), who recognized only two valid subspecies (townsendii and nevadensis). Considered a distinct species by Thaeler (1968b), Patton et al. (1984), Patton and Smith (1989, 1994), and Rogers (1991a, b), despite limited hybridization with bottae in NE California. Hall (1981:469, 495) reviewed Thaeler's evidence and included townsendii in umbrinus (sensu Hall). |
