Ptychochromis onilahy is a species of fish in the cichlid family. It was endemic to the Onilahy River in southwestern Madagascar. Despite several recent visits to the region, this species has not been recorded since 1962 when the only known five specimens were collected.[1] It is listed as extinct by the IUCN (their rating was made before its official description, and is therefore under the temporary name Ptychochromis sp. nov. 'Kotro'),[1] but the Onilahy River system is large, and there is a small chance remnant populations exist in remote regions.[2]
