SPECIES Spermophilus (see comments) erythrogenys

Author:Brandt, 1841.
Citation:Bull. Acad. Sci. St. Petersbourg: 43.
Common Name:Red-cheeked Ground Squirrel
Type Locality:"...vicinity of Barnaul" [Altaisk Krai, Russia] (Ognev, 1963a:60).
Distribution:E Kazakhstan, SW Siberia (Russia). Formerly included an isolated population (pallidicauda) in Mongolia and Inner Mongolia (China), which is here given full species status along with brevicauda.
Status:IUCN – Lower Risk (lc).
Comments:Subgenus Colobotis according to Gromov et al. (1965:315), but see Hall (1981:381) who included Colobotis in subgenus Spermophilus. Ellerman and Morrison-Scott (1951:508, 511) regarded brevicauda, intermedius and carruthersi as synonyms of pygmaeus, and pallidicauda as a full species. Sludskii et al. (1969) considered intermedius (= brevicauda) a full species; while Corbet (1978c:84) provisionally included these taxa in major; but see Gromov et al. (1965:315), Vorontsov and Lyapunova (1970), and Nikol'skii (1984) for evidence of specific distinctness from major. The names ungae (Martino, 1923), ilensis (Belyaev, 1945), and heptneri (Vasil’eva, 1964) are particularly unstable. Ognev (1947) placed ungae in erythrogenys, and omitted ilensis, as did Ellerman and Morrison-Scott (1955). Gromov et al. (1965) placed ungae, and the newly described heptneri, in major, but heptneri was considered a junior synonym of ungae; ilensis was placed in brevicauda, but considered invalid because it is infrasubspecific. Pavlinov and Rossolimo (1987) placed all three, as well as brevicauda, in erythrogenys, without comment. Finally, Hoffmann et al. (1993) placed ilensis in erythrogenys, and ungae plus heptneri in major. The present treatment was reached after plotting the type localities of all taxa on distribution maps of the three species (brevicauda, erythrogenys, and major); ungae and heptneri fall within the range of erythrogenys, while ilensis is within brevicauda.
