This is a small family confined to Australia, New Zealand and South America. Adults of Australian species are of medium size (body 8-28 mm, fore wing 4-24 mm) and characterised by a pronotum with sharp or produced corners. Larvae have a similar pronotum, live in streams under stones or in gravel and are often associated with organic debris or logs.
