SPECIES Thomomys (Megascapheus) bottae
| Author: | Eydoux and Gervais, 1836. | | Citation: | Mag. Zool., Paris, 6: 23. | | Common Name: | Botta’s Pocket Gopher. | | Type Locality: | USA, coast of California (restricted to vicinity of Monterey, Monterey Co., by Baird, 1857). | | Distribution: | SW and W USA, north to Oregon, east to Colorado, and south to the Cape region of Baja California, Sinaloa and Nuevo Leon (Mexico). | | Status: | IUCN – Lower Risk (lc). | | Comments: | Subgenus Megascapheus. The taxonomic history of this, and related species has been contentious. Hall and Kelson (1959) included bottae within umbrinus but considered baileyi and townsendii as separate species, but Hall (1981) included all four of these taxa within his concept of umbrinus. Anderson (1966, 1972), Hoffmeister (1969, 1986), and Patton and co-workers (Patton, 1973; Patton and Dingman, 1968; Patton and Smith, 1981) considered bottae (including baileyi) separate from umbrinus. Thaeler (1968b), Patton et al. (1984), Patton and Smith (1989, 1994), and Rogers (1991a, b) supported the specific separation of townsendii from Hall's (1981) umbrinus. As envisioned here, bottae includes a number of taxa considered by earlier workers to be full species but each of which are now relegated to subspecific status or are recognized as synonyms of other subspecies (taxa marked by asterisks in the list of synonyms, above). Hoffmeister (1969), Patton and Dingman (1968), and Patton (1973) reported on hybridization between bottae and umbrinus in S Arizona; Thaeler (1968b), Patton et al. (1984), and Patton and Smith (1993) examined hybridization between bottae and townsendii in NE California. For subspecies, see Hall (1981), exclusive of those herein allocated to townsendii and umbrinus, and as modified for Arizona by Hoffmeister (1986) and for California by Patton and Smith (1990). |
