Synodontis macrostigma, known as the largespot squeaker, is a species of upside-down catfish that is native to Angola, Botswana, Namibia, South Africa and Zambia where it is found in the Cunene, Okavango, upper Zambezi and Kafue River systems. It was first described by British-Belgian zoologist George Albert Boulenger in 1911, from specimens collected in the Okovango River, Botswana, by R. B. Woosnam. The species name macrostigma is derived from the Greek word makros, meaning "large", and the Greek word stigma, meaning "mark" or "spot" and refers to the large spots on the sides of the fish.
