Ptychochromis onilahy is a species of cichlid 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 initial rating was made before its official description, and therefore listed 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] This species can reach a length of 8.6 centimetres (3.4 in) SL.[3]
