Justification: It has been many decades (early 1960s) since any specimen of this taxon has been caught in Lac Itasy. The lake and surrounding region are highly degraded and numerous exotics (potential competitors and predators) are established. Despite continued reports of the persistence of a relict population of cichlids resembling this species in the upper reaches of both the Tsiribihina and Ikopa Rivers, no Ptychochromoides have to date been collected from either drainage. Under the circumstances (targeted collecting efforts, presence of numerous exotics, and time lapsed since last collected), it is defensible to treat this species as Extinct. |
