Hypsolebias

Hypsolebias is a genus of small fish in the family Rivulidae that are endemic the Caatinga, Cerrado and nearby regions in Brazil. The greatest richness is in the São Francisco River basin, but there are also species in the Tocantins, Jequitinhonha and Jaguaribe systems, as well as smaller river basins in northeastern Brazil.[2][3] Like their relatives, Hypsolebias are annual killifish.[4] The short-lived adults inhabit temporary waters like rain pools, laying their eggs in the bottom. As their habitat dries up the adults die, but the eggs survive and hatch when the water returns in the next season.[2]

The males are more colorful than the females, and male colors/patterns are a primary way of separating the different species.[2] They are small fish that reach up to 7 cm (2.8 in) in total length.[5]

Hypsolebias was formerly regarded as a subgenus of Simpsonichthys.[2][6] Although this split is generally accepted, a genetic study indicates that Hypsolebias is not monophyletic.[7]

gollark: It's undocumented if you have to rely on a random third party source. Especially when half of them disagree with each other.
gollark: I don't want to delve into cryptic undocumented realms of configuration to apply tweaks which will randomly break later.
gollark: On Arch the only "set dates" are stuff like "you need to update pacman within a year or so before we break backward compatibility".
gollark: Well, enjoy randomly being interrupted!
gollark: It's like being angry if they came up to me and forced it down my throat if I didn't eat it within 10 seconds.
