Kozlov's accentor (Prunella koslowi) or the Mongolian accentor, is a species of bird in the family Prunellidae. It is found in Mongolia and northern China.
The specific epithet was chosen to honour the Russian explorer Pyotr Kozlov.[1]
The name Tharrhaleus pallidus Menzbier, 1887 was published just months after the scientific name to which this species is now recognized: Accentor Koslowi Przewalski; therefore, it is a synonym of it.[2]
