Taxonomy
The brown-chested alethe was formally described in 1850 by the French naturalist Charles Lucien Bonaparte based on a manuscript by Coenraad Temminck. Bonaparte gave the binomial name as Trichophorus and the [type type locality (biology)|locality (biology)|locality] as Africa. The locality has been restricted to the island of Bioko. The specific epithet combines the Ancient Greek polios meaning "grey" with -kephalos meaning "-headed". The brown-chested alethe is now one of four species placed in the genus Chamaetylas that was introduced in 1860 by Ferdinand Heine.Nine subspecies are recognised:C. p. poliocephala – Sierra Leone to GhanaC. p. compsonota – south Nigeria to southwest Central African Republic, northwest Angola and BiokoC. p. hallae – west AngolaC. p. giloensis – south SudanC. p. carruthersi – southeast Central African Republic, northeast DR Congo, Uganda and west KenyaC. p. akeleyae – central KenyaC. p. vandeweghei – Rwanda and BurundiC. p. kungwensis – west TanzaniaC. p. ufipae – southeast DR Congo and southwest Tanzania
