Taxonomy

It was previously considered conspecific with the Siberian (lesser) sand plover, and includes three subspecies: A. a. atrifrons, breeds in Tibet, A. a. pamirensis breeds in Pamir Mountains, and A. a. schaeferi, breeds in Qinghai.^[2]

A study published in 2022 proposed that the "mongolus" group of lesser sand plover is the sister group of greater sand plover, and "atrifrons" group is the sister group of them also. So a taxonomic split of lesser sand plover was needed. The authors suggested new scientific and common English name for them:^[3]

• Siberian sand plover (Anarhynchus mongolus), A. m. mongolus and A. m. stegmanni;
• Tibetan sand plover (Anarhynchus atrifrons), A. a. atrifrons, A. a. pamirensis and A. a. schaeferi;
• Desert sand plover (Anarhynchus leschenaultii), currently greater sand plover.

The International Ornithologists' Union accepted the split and renaming of the lesser sand plover in 2023, erecting the Tibetan sand plover as a full species.^[2]
