Once the genus Rivulus was one of the most specious genus of killifish at all. Nowadays, more and more species are placed in different, smaller genera. This splitting is not always supported by the majority of scientists, and so some of them call still all species Rivulus, other scientists follow the splitting. In the case the splitting is justified, tecminae is placed in the genus Laimosemion. This fish occurs in the Orinoco basin in Venezuela and in the upper Rio Negro in Brazil. Our specimens, which we could import currently for the first time ever, come from Venezuela.
