[3] S. raddei ranges through much of northern China, Mongolia, and the Russian Far East, and is also found in North Korea.

The Mongolian toad is relatively small, with adults not exceeding a snout-to-vent length (SVL) of 9 cm (3.5 in).

[4] The mating season of S. raddei occurs between March and July, depending on the local climate.

When adult, the Mongolian toad favours ants as food, particularly in arid regions.

The Mongolian toad was classified as Bufo raddei prior to the 2006 definition of the genus Pseudepidalea.
