Onilahy River
Onilahy is a river in Toliara Province, southern Madagascar. It flows down from the hills near Betroka to the Mozambique Channel. It empties at St. Augustin (23°34′00″S 43°45′00″E / 23.5666667°S 43.75°E), and into the Bay of Saint-Augustin.
Two species of cichlids are endemic to the river basin, but Ptychochromis onilahy is probably already extinct[1] and the remaining range of Ptychochromoides betsileanus covers less than 10 square kilometres (3.9 sq mi).[2]
