Maratecoara is a genus of killifish in the family Rivulidae.[2] These annual killifish are endemic to seasonal pools, swamps and lagoons in the upper AraguaiaTocantins and middle Xingu river basins in Brazil.[3][4] Most are from savanna regions, but M. gesmonei is from the Amazon rainforest.[4]

They are small fish, up to 5 cm (2.0 in) in total length.[2] The males are mottled or spotted orange-red and turquoise-blue, and have long, pointed fins. The much duller females have "normal" fins.[3][4]

Species[edit]

Maratecoara and the closely related Papiliolebias, Pituna, Plesiolebias and Stenolebias form a clade, Plesiolebiasini.[3]

There are currently 4 recognized species in Maratecoara:[2]
