There are five races, which fall in two groups:
- mongulus are the large east Asian forms, C. m. mongolus and C. m. stegmanni which are sometimes given specific status as Mongolian Plover, Charadrius mongolus.
- atrifrons consists of atrifrons, pamirensis and schaeferi which, if the taxonomic split is accepted, becomes a narrower Lesser Sandplover Charadrius atrifrons.
