P. e. rhodoptera (Shelley, 1880) – Kenya to eastern Zimbabwe and Mozambique
Most taxonomists place this species in the genus Prinia rather than in its own monotypic genus Heliolais.[6][7] Support for this alternative placement is provided by a molecular phylogenetic study of the Cisticolidae published in 2013 that found that the red-winged warbler was closely related to the prinias.[8]
