GENUS Thomomys
| Author: | Wied-Neuwied, 1839. | | Citation: | Nova Acta Phys.-Med. Acad. Caes. Leop.-Carol., 19(1): 377. | | Type Species: | Thomomys rufescens Wied-Neuwied, 1939 (= T. talpoides rufescens). | | Comments: | Recent species allocated to two subgenera (Thaeler, 1980): Thomomys and Megascapheus. Patton and Smith (1981) and Smith (1998) examined phylogenetic relationships among members of the subgenus Megascapheus based on molecular characters. Species boundaries for some forms are poorly defined, but Patton and Smith (1989, 1994) provided an operational definition that can be applied to all pocket gophers. |
