Taxonomy

The chestnut-headed tesia was formally described by the English army officer and zoologist Edward Burton in 1836 under the binomial name Sylvia castaneocoronata.^[3] The specific epithet combines the Latin castaneus meaning "chestnut-coloured" and coronatus meaning "crowned".^[4] Formerly placed in the genus Tesia, a molecular phylogenetic study published in 2011 found that the chestnut-headed tesia was embedded in a clade containing members of the genus Cettia.^[5][6]

Three subspecies are recognised:^[6]

• C. c. castaneocoronata (Burton, 1836) – Himalayas and northeast India to south China and north Laos
• C. c. abadiei (Delacour & Jabouille, 1930) – north Vietnam
• C. c. ripleyi (Deignan, 1951) – Yunnan (south China)
