Austrofundulus

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]

They are small thickset fish, no more than 10 cm (3.9 in) in total length,[4] and most less than half that size.[2]

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]

  • Austrofundulus guajira Hrbek, Taphorn & Thomerson, 2005
  • Austrofundulus leohoignei Hrbek, Taphorn & Thomerson, 2005
  • Austrofundulus leoni Hrbek, Taphorn & Thomerson, 2005
  • Austrofundulus limnaeus L. P. Schultz, 1949
  • Austrofundulus myersi Dahl, 1958
  • Austrofundulus rupununi Hrbek, Taphorn & Thomerson, 2005
  • Austrofundulus transilis G. S. Myers, 1932
