Distribution and remarks: a Lower Guinea endemic, found from the Mbei (or Mbe) and Komo River drainage systems in north-western Gabon southward across western Gabon and Cabinda to the Chiloanga River. Also extends to Angola, Congo and Democratic Republic of the Congo with a recent record from the Rio Combe in the extreme southwest of Equatorial Guinea in 2018 (Van der Zee, pers. com.). Aphyosemion striatum microphthalmum is considered as valid as A. microphthalmum Lambert & Géry, 1968 , by some authors, to be verified.
