Oligoneuriidae

Oligoneuriidae is a family of mayflies with a pantropical distribution. They are also known as brushlegged mayflies due to the presence of two rows of setae used for filtration on the front legs of their nymphs. Nymphs also have tufts of gills at the base of their maxillae. There are at least 68 described species in over a dozen genera.
