Cicerbita auriculiformis is closely related to C. roborowskii, although well distinct by its smaller capitula with only 5 inner phyllaries. This relationship was clearly expressed by S. W. Liu and T. N. Ho (Fl. Qinghai. 3: 512. 1996) when publishing it under the name Chaetoseris qiliangshanensis. However, the species had been known before, but it was, for its small capitula, misplaced in Stenoseris as S. auriculiformis (e.g., FRPS 80(1): 286. 1997).
