Distribution.

China (Inner Mongolia, Taiwan). In literature the records for mainland China are listed under the name pygialis du Buysson and the Taiwanese citations are listed under the name sauteri. It is widely distributed in the Palearctic from Europe to the Russian Far East and in the Nearctic, where it is very likely to have been introduced via commerce ( Kimsey and Bohart 1991; Kurzenko and Lelej 2007).

Remarks.

Du Buysson described pygialis based on two syntypes collected in China and Caucasus: " Deux esemplaires ♂♀: Chine, Caucase " [not Chinese Caucasus as listed in Kimsey and Bohart, 1991]. Tsuneki (1946) considered Ellampus potanini as synonym of sauteri.
