Robert’s Stonefly (Alloperla roberti)

Robert’s Stonefly was described in 1981, apparently based on material that had already been collected in 1860 from somewhere in the Rock Island County of Illinois, USA.

The species has not been found since the collection of the type material and is very likely extinct.
