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 (Griniger) and the locality as Africa. The locality has been restricted to the island of Bioko (formally Fernando Po).[2][3] The specific epithet combines the Ancient Greek polios meaning "grey" with -kephalos meaning "-headed".[4] The brown-chested alethe is now one of four species placed in the genus Chamaetylas that was introduced in 1860 by Ferdinand Heine.[5]

Nine subspecies are recognised:[5]

  • C. p. poliocephala (Bonaparte, 1850) – Sierra Leone to Ghana

  • C. p. hallae (Traylor, 1961) – west Angola
  • C. p. giloensis (Cunningham-Van Someren & Schifter, 1981) – south Sudan
  • C. p. carruthersi (Ogilvie-Grant, 1906) – southeast Central African Republic, northeast DR Congo, Uganda and west Kenya
  • C. p. akeleyae (Dearborn, 1909) – central Kenya
  • C. p. vandeweghei (Prigogine, 1984) – Rwanda and Burundi
