Austrolebias is a genus of killifish in the family Rivulidae. These annual killifish live in temporary pools, swamps and streams in the Río de la Plata, PatosMirim and Mamoré basins in South America.[3][4]

Most species are small, less than 10 cm (3.9 in) in total length, but a few reach 15–22 cm (5.9–8.7 in), making them some of the largest killifish (only a few Fundulus, Moema and Orestias reach a similar or larger size).[3][5]


There are currently 46 recognized species in this genus:[5]
