Isoperla jewetti Szczytko & Stewart

Grande Stripetail Stonefly (Isoperla jewetti)  

This species was described in 1976 from specimens that had been collected in 1939 from a single location in El Paso County, Texas, which is now completely destroyed by agriculture.  

The species is furthermore known from a single specimen collected in Huerfano County, Colorado, and from at least six nymph specimens that were collected in Dona Ana County, New Mexico.  

The Grande Stripetail Stonefly was not recorded since 1980 and is most likely extinct.
