Smith’s Zokor
French: Zokor de Smith / German: Smith-Blindmull / Spanish: Zocor de Smith
Taxonomy. Myospalax smithii Thomas, 1911 View in CoL ,
30 mi (48 km) SE of Tao-chou , Gansu, China.
G. M. Allen in 1940 suggested that E. smith-#2 may be a hybrid between E. rothschildi x E. cansus , but subsequent authorities have not adopted this position. On the basis of tooth morphology and smaller body size, M. A. Lawrence in 1991 argued for a sister relationship to E. rothschildi . Molecular data weakly suggest a close relationship to E. rufescens or E. baileyi . Monotypic.
Distribution. Gansu, Ningxia, N Sichuan, and W Shaanxi (C China). View Figure
Descriptive notes. Head-body 162-255 mm,tail 34-39 mm; weight 180-460 g. Smith's Zokor has dark brown dorsal pelage, with slight cinnamon colored tips. Back of head is dark gray to velvety black, area around ears is dark brown, and vibrissae are black and white. White forehead blaze is present in some individuals. Venter is grayish brown, also mixed with cinnamon. Immature individuals are bluish gray, with sooty gray head.

Breeding. Breeding of Smith’s Zokor peaks in June-July, and offspring are born in May-September. Litter size is usually 2-4 young but can be as high as eight young. Females produce two litters annually.
Activity patterns. No information.
Movements, Home range and Social organization. Smith’s Zokors construct complex burrows in soft wetsoils.
