Taxonomy
The black-backed cisticola was described by the German explorer and ornithologist Theodor von Heuglin in 1869 from a specimen collected near the Bahr el Ghazal River in South Sudan. He coined the binomial name Drymoeca eximia. The specific epithet eximius is the Latin for "select" or "distinguished". The species is now placed in the genus Cisticola which was erected by the German naturalist Johann Jakob Kaup in 1829.

Three subspecies are recognised:
 C. e. occidens Lynes, 1930 – south Senegal to Nigeria
 C. e. winneba Lynes, 1931 – south Ghana
 C. e. eximius (Heuglin, 1869) – Congo and Central African Republic to Eritrea, Ethiopia, west Kenya and north Tanzania
