ED51AE2DFFCF7B4594F6FD55BE45E79D.taxon	distribution	Published Records: Adult Sierraperla examined in this study indicate S. cora is restricted primarily to the Sierra Nevada and Warner Mountains of eastern and northeastern California and potentially western Nevada in the Lake Tahoe area. Other populations in northwestern California and southern Oregon, except one population from Black Butte Spring near Weed, California, are referred to the new species, S. tolowa. The following list provides a summary of the previously published sites that we assign, at least tentatively, to S. cora. California: Jewett (1954) referred to “ A nearly mature nymph … ” collected by H. P. Chandler in Plumas Co. at Howells [Road?], 29 August 1946. Jewett (1960) gives apparently valid records from Colusa Co., (Paradise Creek), El Dorado Co., (Pyramid Ranger Station), Plumas Co., (2 sites, Howells, and tributaries of Smith Creek near Blairsden), Shasta Co., (2 sites, Hat Creek and Shingletown). Nelson & Stark (1987) list one site from Shasta County, and Stark et al. 2008 report collections from six Modoc Co. sites. Nevada: (Needham & Smith 1916; Needham & Claassen 1925) both list the holotype female from Reno, collected in 1878 by Morrison.	en	Stark, Bill P., Kondratieff, Boris C., Sandberg, John B., Gill, Brian A., Verdone, Chris J., Harrison, Audrey B.

Head mostly yellow brown, usually with an irregular narrow bar extending across median frons forward of ocelli and often with a narrow brown band extending between ocelli; occiput yellow-brown, sometimes with obscure dusky pigment; some specimens have more extensive dark pigment forward of ocelli. Pronotum with numerous irregular pale spots, some bearing small dark inclusions, particularly in median half of pronotum. Femora yellow-brown to brown, but sometimes slightly darker along dorsal margin; tibiae usually yellow-brown. Wing membrane brown with darker veins except along C and Sc (Fig. 33). Male.

ED51AE2DFFCB7B4F97B9FBE4BEE1E079.taxon	etymology	Etymology. The species name honors the Native American Tolowa people whose homeland, based in northwestern California and southwestern Oregon, may have encompassed the site in Del Norte County, California where the type specimen was collected.	en	Stark, Bill P., Kondratieff, Boris C., Sandberg, John B., Gill, Brian A., Verdone, Chris J., Harrison, Audrey B. (2015): Sierraperla Jewett, 1954 (Plecoptera: Peltoperlidae), Distribution, Egg Morphology And Description Of A New Species. Illiesia 11 (2): 8-22, DOI: 10.5281/zenodo.4760527
ED51AE2DFFCB7B4F97B9FBE4BEE1E079.taxon	diagnosis	Diagnosis. This species appears distinct by virtue of its dark habitus, the bilobed lateral aedeagal lobes, the chorionic detail of the anterior pole of the egg and the barcode sequence of the COI gene. Females may be separated by comparison of subgenital plate shape and size of the median notch. No morphological characters are known which permit separation of larvae of the two species of Sierraperla. Because present data suggests the two species are allopatric we assigned identifications of some larval specimens on this basis when no barcode or adult data were available. Sierraperla cora is known from sites in the Sierra Nevada and Warner Mountains of California and Nevada, whereas S. tolowa is known from the Coast and Cascade mountains of southern Oregon and northern California. A possible exception to the allopatric distribution occurs in Siskiyou Co., California, where populations of both species were discovered near Mt. Shasta. Adult specimens from Big Spring, Mt. Shasta City Park were diagnosed based on the dark habitus, bilobed lateral aedeagal lobes and chorionic detail of the anterior pole (Figs. 24 - 26), and larval specimens from this site and Black Butte Spring, near Weed were diagnosed by comparing COI sequences. Adults and larvae from the Mt. Shasta City Park site are both identified as S. tolowa. Unfortunately, no adult specimens are available from Black Butte Spring but the larval COI sequence from this population is consistent with that of other S. cora populations.	en	Stark, Bill P., Kondratieff, Boris C., Sandberg, John B., Gill, Brian A., Verdone, Chris J., Harrison, Audrey B.

ED51AE2DFFCB7B4F97B9FBE4BEE1E079.taxon	distribution	Distribution. Sierraperla is currently known from a region of northern California, southern Oregon and western Nevada. The northernmost known locality is a site in Jackson Co., Oregon at Pearsony Falls on Mill Creek, the southernmost known locality is Bendorf Spring in El Dorado Co., California, the westernmost site is in Elk River Canyon, Curry Co., Oregon, and the easternmost site is in Douglas Co., Nevada (R. Bottorff, personal communication). Sierraperla appears to be rare along the western slope of the Coast Range but has been collected from upper Freshwater Creek in Humboldt Co., California by a colleague (J. J. Lee, personal communication).	en	Stark, Bill P., Kondratieff, Boris C., Sandberg, John B., Gill, Brian A., Verdone, Chris J., Harrison, Audrey B.

ED51AE2DFFCB7B4F97B9FBE4BEE1E079.taxon	description	DNA barcoding. Of the 48 specimens submitted, CCDB returned 44 high quality sequences (~ 92 %) meeting the standards for barcode compliance of the Consortium for DNA Barcoding (CBOL) for Sierraperla cora (N = 19), S. tolowa (N = 24) and Soliperla campanula (N = 1). Mean genetic distances among individuals of S. cora and S. tolowa were 0.3 % and 0.8 % respectively (very similar). The mean genetic distance among specimens of these two species was 9 % (quite divergent). Therefore, low levels of intraspecific and high levels of interspecific divergence of DNA barcode sequences among individuals of these taxa provide further support for the recognition of S. tolowa as a species distinct from S. cora (Hebert et al. 2003, Sweeney et al. 2011, Zhou et al. 2009). Mean genetic distances among S. cora, S. tolowa and exemplars of the other western peltoperlid genera (Soliperla and Yoraperla) calculated here are presented in Table 1 for reference.	en	Stark, Bill P., Kondratieff, Boris C., Sandberg, John B., Gill, Brian A., Verdone, Chris J., Harrison, Audrey B.
