Until recently considered to constitute several species, with splits of althaea and minula (with margelanica), and this may ultimately be more appropriate. Nuclear DNA, however, fails to support clades based on mtDNA, and, although althaea is relatively well marked, characters used to define species (and subspecies) limits prove too weak for taxa to pass tests of diagnosability#R. Treatment of these forms under a single species currently therefore inevitable#R. Geographical variation largely clinal, race halimodendri intergrading widely with nominate in S Siberia. Proposed races caucasica (Turkey, Caucasus and N Iran) and zagrossiensis (SW Iran) barely separable from nominate; similarly, telengitica (Russian Altai and Mongolia) included in margelanica. Proposed race snigirewskii (Turkmenistan) largely inseparable from minula, and jaxartica (S Kazakhstan) falls within range of clinal variation of halimodendri; poorly differentiated chuancheica (upper R Huang He, S of Gobi, in N China) included in margelanica. Birds from Alai and Pamir Ranges E to Tien Shan sometimes separated as race monticola, but not reliably distinguishable from those in rest of range of althaea. Six subspecies recognized.

Subspecies and Distribution
  • S. c. curruca (Linnaeus, 1758) – Lesser Whitethroat – Europe (E from S Fennoscandia, Britain and N, C & SE France) E to the Urals, S to N Italy, Balkans, Asia Minor, Levant, the Caucasus and NW & SW Iran; winters mainly in C & NE Africa, but also in the Middle East.
  • S. c. blythi Ticehurst & Whistler, 1933 – boreal forests from the Urals E to Transbaikalia, S to N Altai, N Mongolia and S Siberia#R#R; non-breeding probably in NE Africa, the Middle East and S Asia.
  • S. c. halimodendri Sushkin, 1904 – Kazakhstan (from lower Volga) E to W Mongolia, S to SE Caspian region, E Iran, W Afghanistan, N Tien Shan and extreme NW China (N Xinjiang)#R#R; winters mainly in Arabia, S Asia and probably NE Africa.
  • S. c. minula A. O. Hume, 1873 – Small Whitethroat – dry steppes in W China (Tarim Basin in Xinjiang and W Qinghai); non-breeding in Pakistan and NW India.
  • S. c. margelanica Stolzmann, 1898 – CN & N China from SW Gobi S to Lop Nur and Qaidam Pendi, E to Ningxia (R Huang He); range probably also includes Russian Altai and NW & E Mongolia#R. Non-breeding range presumed S Asia.
  • S. c. althaea A. O. Hume, 1878 – Hume's Whitethroat – mountains of SE Kazakhstan (Karatau Mts) E to SW & C Tien Shan, S in mountains to NW Himalayas (Kashmir, Ladakh), S Turkmenistan, NE & SE Iran, Afghanistan and W Pakistan; non-breeding from S Iran (probably also S Iraq and S Afghanistan) E to S India and N Sri Lanka, probably also SE Arabian Peninsula.
