Abstract
Stoneflies of the Neoperla clymene (Newman) species complex in Illinois were reexamined from museum and newly collected adult material. Seven species have historically been present in the state. The previously known species, N. clymene, is joined by six new state records including N. catharae Stark and Baumann, N. harpi Ernst and Stewart, N. mainensis Banks, N. occipitalis (Pictet), N. robisoni Poulton and Stewart, and N. stewarti Stark and Baumann. Four species (N. mainensis, N. occipitalis, N. robisoni, and N. stewarti) are considered extirpated since all records predate 1930. Two species (N. catharae and N. clymene) have had extensive range reductions, while N. harpi has maintained its historical distribution in the state. Large rivers at the periphery of Illinois and small streams in the Shawnee Hills of southern Illinois still maintain populations of Neoperla.
