ResumoFew Plecoptera species records are available from Nebraska. Distribution for nine species of stoneflies in five families from 16 western counties are newly presented. Five new state records include: Capnura wanica (Frison), Isoperla quinquepunctata (Banks), Perlesta cinctipes (Banks), Pteronarcys pictetii Hagen, and Taeniopteryx burksi Ricker & Ross. Our survey indicates that western Nebraska is a mixing zone for typical eastern and midwestern North American and Rocky Mountain species. Presently, no faunal studies on the stoneflies of Nebraska are available. An inventory of aquatic insects is maintained by the Nebraska Department of Envi ronmental Quality, usually at the generic level (Ken Bazata, Nebraska Department of Environmental Quality?pers. comm.). Only eight stonefly species have been recorded from all of Nebraska, and are scattered through the literature. In their review of Nearctic Acroneuria, Stark and Gaufin (1976) listed A. ab normis (Newman) from Douglas County in the eastern half of the state, and Red Willow County in the western half. In 1989 Stark reported Perlesta decipiens (Walsh) from Hall County. Recently, Stark and Rhodes (1996) described Perlesta xube from Cherry County. Three species of Isoperla have been reported from Nebraska: Claassen (1937) originally described /. extensa from Lincoln, Szczytko and Stewart (1978) listed /. bilineata (Say) from Lancaster County in eastern Nebraska, and in a review of North American stonefly species records, Stark et al. (1986) included /. marlynia (Needham and Claassen) and Pteronarcys dorsata (Say) from Nebraska. Finally, Attaneuria ruralis has been listed from Nebraska by Stark (1996); these records are from Colfax and Lancaster counties in eastern Nebraska. Eight species of stoneflies appear extremely low for a state occupying 200,673 km2 in the High Plains and extending 743 km east-to-west and 330 km north-to south. Several adjacent states record substantially more species as compared to Nebraska: Colorado (79), Kansas (26), and Wyoming (83); Iowa and South Da kota report comparable numbers to Nebraska with 9 and 14 species, respectively (Stark et al., 1986, Stark, 1996). We present five new state records of stoneflies collected from 16 of the 27 counties in the western half of Nebraska. This half of the state was selected because it includes (1) the Nebraska Sand Hills region comprised of extensive dune formations cut by numerous streams and several large river systems, (2) the Pine Ridge formation along the state's northern border, a unique area that contains Rocky Mountain floral elements, along with faunal representatives, and (3) the above combinations have created several interesting mixing zones.
