Lee (1997) refers to S. xuecunensis as a metaspecies lacking the autapomorphies of Shihtienfenia.
Tsuji & Müller (2009) seem to consider it a valid taxon for cladistic analysis, and like Lee 1997 place the two Chinese species close to Pareiasuchus.

S. permica (Young and Yeh, 1963); The skull of this pareiasaur is unknown.
It is known originally from a number of isolated vertebrae, jaws, and limb-bones and an incomplete skeleton, all from a single locality (Shiqianfeng Formation at Baode, Shanxi).
Shanshisaurus xuecunensis Cheng, 1980 and Huanghesaurus liuliensis Gao, 1983 are synonyms.

S. completus (Wang, Yi and Liu, 2019); The first pareiasaur skull from Asia came from this species.
