Spectrolebiasis agenusof killifish in thefamilyRivulidae.These annualkillifishareendemicto seasonal waters (like pools) in theParaguay,Tocantins–Araguaia,XinguandMamoré–Grandebasins in Bolivia, Brazil and Paraguay.[2][3][4]Each species generally has a small distribution and some are seriously threatened byhabitat loss;the entire known range ofS. reticulatusis in the area flooded by theBelo Monte Dam.[5]

They are small fish, up to 6 cm (2.4 in) intotal length.[6]As typical of killifish, males are more colorful than females.[2][3][4]
Species
editSpectrolebiaswas formerly regarded as a subgenus ofSimpsonichthys.[7][8][9]Although this split is generally accepted, ageneticstudy indicates thatSpectrolebiasis notmonophyletic.[10]
