SPECIES Stylodipus andrewsi

Author:Allen, 1925.
Citation:Am. Mus. Novit., 161: 4.
Common Name:Andrew’s Three-toed Jerboa
Type Locality:S Mongolia, near Mt. Uskuk (Ussuk), Camp Ondai Sair (Andrews, 1932:101).
Distribution:NW, S, and C Mongolia east of Barun Khurai (Baruun Huuray) Valley; and adjacent China: Nei Mongolia, N Hebei, N Shanxi, N Shaanxi, Gansu, and Ningxia (see Ma et al., 1987; Qin, 1991; Wang, 2003; and Zheng and Zhang, 1990).
Status:IUCN – Lower Risk (lc).
Comments:Ellerman and Morrison-Scott (1951) and Corbet (1978c) included andrewsi as a subspecies of S. telum, but Sokolov and Orlov (1980) recognized it as a distinct species. Sokolov and Shenbrot (1987b) showed that in addition to the retention of a rudimentary P4, S. andrewsi is differentiated from S. sungorus and S. telum in dental and phallic characters, and in greater bullar inflation. The ranges of S. andrewsi and S. sungorus are adjacent but do not overlap (Sokolov and Shenbrot, 1987b). See comments under S. sungorus and S. telum.
