Distribution. This species is restricted to the temperate grassland, semidesert and desert steppe vegetation of Mongolia and the neighbouring areas of southern Siberia, eastern Kazakhstan, and northern China; a distribution map was presented by Putshkov (1986: 98, fig. 54). Its distribution in China can be summarized as follows: Inner Mongolia: Alxa League!, Xilingol League!, Ar Horqin Banner!, several additional localities ( Hsiao 1977; Liu & Nonnaizab 1985; Nonnaizab 1986, 1999; Ma et al. 1991); Qinghai: Qilian!; Ningxia: W foot of Mt. Helan, Khar- Us [Lake] ( Zheng & Gao 1990); Shanxi: Linfen, Yuncheng ( Li et al. 2007); the records from Ningxia and Shanxi could not be verified. The record from Daxing’anling Prefecture, Heilongjiang ( Hsiao 1977), is erroneous, and pertains to M. miriformis gracilis ; Hua (2000) listed it from Sichuan and Xinjiang, but these data are based on unknown sources therefore they are suspicious.
