ARTICLECOLLECTING ENDEMIC AND RARE STONEFLIES (PLECOPTERA) INCALIFORNIA, U.S.A.Richard W. Baumann¹ & Boris C. Kondratieff²¹Department of Biology and Monte L. Bean Life Science Museum,Brigham Young University, Provo, Utah, U. S. A. 84602E-mail: richard_baumann@byu.edu²Department of Bioagricultural Sciences and Pest Management,Colorado State University, Fort Collins, Colorado, U. S. A. 80523E-mail: Boris.Kondratieff@Colostate.eduIntroductionCalifornia is a remarkable state in regard to its geographical and biologicaldiversity. Death Valley in the southeast is 86 m below sea level, the lowest point in theUnited States, and Mount Whitney (4,417 m) is the highest point in the contiguous 48states. It has been estimated that there are more than 27,000 species of insects that occurin California (Ballmer 1995). The myriad of freshwater aquatic habitats in Californiasupport an amazing number of aquatic insect species (Usinger 1956, McElravy et al.1989), including stoneflies. Jewett (1956) in the classic volume: “Aquatic of Insects ofCalifornia,” listed 93 species of stoneflies from the state and then in 1960, he listed 101species, noting that this number would increase. Currently, there are at least 186 speciesof stoneflies recorded from California (Stark et al. 2009, Baumann and Kondratieff 2009,Kondratieff and Lee 2010, Lee and Baumann 2010, Baumann and Kondratieff 2010).What makes California unique among all other states of the United States is that 39% ofthe 186 species or 72 species are only known from the state. For example, Nelson andBaumann (1987) described fifteen new species of Capnia in a single publication, allendemic to California.A collecting trip was organized by John B. Sandberg of Chico, California to occurfrom April 25-29, 2010 to collect endemic or rare taxa of California stoneflies, especiallyin the central Sierra Nevada foothills.Materials and MethodsAdult stoneflies were collected using a beating sheet and specimens werepreserved in 80% ethanol. Additionally, nymphs were collected from selected streamsand returned to Colorado State University for rearing. Material was studied using WildM-8 stereomicroscopes. Specimens listed in this study are located at Brigham YoungUniversity, Provo, Utah (BYUC) and Colorado State University, Fort Collins, Colorado(CSUC).13
