Spectrolebias is a genus of killifish in the family Rivulidae. These annual killifish are endemic to seasonal waters (like pools) in the Paraguay, Tocantins–Araguaia, Xingu and Mamoré–Grande basins in Bolivia, Brazil and Paraguay.[2][3][4] Each species generally has a small distribution and some are seriously threatened by habitat loss; the entire known range of S. reticulatus is in the area flooded by the Belo Monte Dam.[5]
They are small fish, up to 6 cm (2.4 in) in total length.[6] As typical of killifish, males are more colorful than females.[2][3][4]
Species
[edit | edit source]Spectrolebias was formerly regarded as a subgenus of Simpsonichthys.[7][8][9] Although this split is generally accepted, a genetic study indicates that Spectrolebias is not monophyletic.[10]
There are currently 9 recognized species in Spectrolebias:[6]
- Spectrolebias bellidoi D. T. B. Nielsen & Pillet, 2015[2]
- Spectrolebias brousseaui D. T. B. Nielsen, 2013[3]
- Spectrolebias chacoensis (L. H. Amato, 1986)
- Spectrolebias costai (Lazara, 1991)
- Spectrolebias filamentosus (W. J. E. M. Costa, Barrera & Sarmiento, 1997)
- Spectrolebias inaequipinnatus (W. J. E. M. Costa & G. C. Brasil, 2008)
- Spectrolebias pilleti D. T. B. Nielsen & Brousseau, 2013[4]
- Spectrolebias reticulatus (W. J. E. M. Costa & D. T. B. Nielsen, 2003)
- Spectrolebias semiocellatus W. J. E. M. Costa & D. T. B. Nielsen, 1997
