Austrofundulus is a genus of killifish in the family Rivulidae native to northern Colombia, northern Venezuela and southwestern Guyana.[2] They are annual killifish where adults generally have a short life in temporary ponds or swamps and the eggs experience a period of drought, only hatching when again covered by water.[3]

Species

Austrofundulus is closely related to Rachovia,[2] and it has been suggested that the former should be merged into the latter.[5]

There are currently 7 recognized species of Austrofundulus:[4]
