We are including <i>C. shasta</i> in the <i>C. ventura</i> Subgroup based on the epiproct structure. <i>Capnia shasta</i> can be distinguished from the other subgroup members by features given in Nelson and Baumann (2009) and by the short lower process of the epiproct described herein.</p> <p> <b>Phylogeny.</b> The cladogram given as Fig. 10 in Nelson and Baumann (2009) showed <i>C. shasta</i> as part of a polytomy with members of the <i>C. californica</i> Group. This hypothesis needs to be re-evaluated based on the actual state of the epiproct of <i>C. shasta</i> presented herein. With the recognition of the lower process of the epiproct, three characters in the matrix of Nelson and Baumann (2009) must be recoded: character 5 changes from 1 to 0 by redefining the appropriate upper process; 17 changes from 0 to 1 indicating an apomorphic deep notch between the two processes of the epiproct; and 18 changes to an apomorphic narrow lower process. In using the branch rearrangement facility in MacClade 4.08a (Maddison and Maddison 2005), two most parsimonious trees result, both of which clearly move <i>C. shasta</i> into the <i>C. ventura</i> Subgroup and require little change to the Nelson and Baumann (2009) hypothesis of relationships. One places <i>C. shasta</i> basal to all members of the subgroup (from <i>C. regilla</i> to <i>C. ventura</i> in Fig. 10 of Nelson and Baumann (2009)) and the other places this taxon further up the tree between <i>C. regilla</i> and <i>C. saratoga</i>. Analysis using new information we present here resolved the tree to a more basal polytomy and by consensus created a polytomy further up the tree, within the <i>C. ventura</i> Subgroup. Resolution of this polytomy will require using additional morphological or molecular characters.</p> <p> <b>Distribution.</b> The most recent collections of <i>C. shasta</i> were made in small creeks that the authors predict have reduced surface flow in the summer.

(Figs. 1-9) Capnia umpqua, Nelson & Baumann 1989:306, Figs. 177 – 180, 252, map Fig. 263 (Not Capnia umpqua Frison 1942) Material examined. ♂ holotype, female allotype, and 2 male and 4 female paratypes, USA, California, Shasta Co., Sulphur Creek, Castle Crags State Park, 16 February 1985, R.W. Baumann & C.R. Nelson. The locality was checked with Google Earth internet software on 17 June 2009 and found the location just outside of the park at: N 41.15587° W 122.36285° elev. 708 m. Each primary type specimen has been placed in a separate vial, in 70% ethanol. One paratype male and the allotype female were the specimens illustrated in Nelson & Baumann (1989) as C. umpqua. Of the paraptypes, one male and three females are in 70% ethanol and the terminalia of 2 males and one female are dried and on SEM stubs, including the specimens used for Figs. 1-8 (the remainders of these specimens are in 70% ethanol vials). The holotype and allotype are deposited at the Smithsonian Institution, United States National Museum, Washington, D.C. (USNM). All paratypes are housed at the R. W. Baumann Aquatic Insect Collection, Monte L. Bean Life Science Museum, Brigham Young University, Provo, Utah (BYUC). Male. Body length 5.10 mm; interocular distance 0.57 mm; wings macropterous, forewing length 5.9 mm; tergum 9 divided along one-half its length by medial membranous area, anterior margin heavily sclerotized. Well-developed tergal knobs present along inner margin of the divided tergum nine (Figs.1-4), no tergal knobs on segment eight; epiproct broad, length 285 m, epiproct width 132 m, measured in dorsal view (Figs. 1, 3) with only a single process well-developed (Figs. 2, 4); apex of epiproct unforked (Figs. 1, 3, 5). Female. Body length 6.48 mm; interocular distance 0.62 mm; wings macropterous, forewing length 6.80 mm; subgenital plate triangular with apex directed anteriorly (Figs. 8, 9); subgenital plate width 0.46 mm on hind margin; hind margin straight with margin thickened and not overlapping sternite 9; subgenital plate with paired lateral light thinnings of sclerotization near distal corners, immediately anterior to the hind margin, darker lines (probably internal) running much of the length of subgenital plate near medial line (Figs. 8-9). Etymology. This species is named for prominent Mount Shasta of the Cascade Range in northern California as a noun, without gender, in apposition. It shares this name with a common, somewhat generic brand of soda water common in the western United States. Diagnosis. Capnia shasta is unique in that it is the only member of the Californica Group with tergal knobs only on segment 9 and no distinctively divided process on the epiproct. It lacks the distinct upper process of the epiproct found in the Ventura Subgroup. It differs from the Californica Subgroup in lacking knobs on tergum 8. Phylogenetic relationships of C. shasta with all known members of the Californica Group are summarized in Fig. 10. Discussion. Nelson & Baumann (1989) predicted that the area in California between Santa Barbara and Carmel would probably be a site for a new species or two yet to be discovered in the Californica Group. To this date, no one has reported any new records of Capnia species from this area but in this paper we describe C. shasta, from a more northerly thought-to-be-well-collected and central portion of the overall group range. The challenge remains to find coastal new members of the group in northern California. Key to males. All males of the previously known species in the Californica Group except true C. umpqua can be identified using the key (p. 304) of Nelson & Baumann (1989). The following key is a modification of the 1989 key written to accommodate both true C. umpqua and C. shasta. Couplet numbering follows that key, with couplet 8 added and figures from various sources noted. 7(4) Terga 5 and 6 each bearing paired knobs (Figs. 69 and 70 of Nelson & Baumann 1989) …………………………………… jewetti Frison 7’ Terga 8 or 9 bearing paired knobs (Figs. 1-4 and 7 in this publication and Figs. 177-178 of Nelson & Baumann 1989) ………………….... 8 8(7) Terga 8 bearing paired knobs (Figs. 1-2 in Baumann & Stewart 2009) ……. umpqua Frison 8’ Terga 9 bearing paired knobs (Figs. 1-4 in this publication; Figs. 177-180 in Nelson & Baumann 1989; and Figs. 3-4 in Nelson 2004 …………………………….. shasta, new species Phylogeny. A purported phylogeny for the entire Californica Group was produced in (Nelson 2004). In the 2004 paper, the species illustrated (and used for the phylogenetic analysis) as C. umpqua was the species we herein describe as C. shasta. Table 1 summarizes the morphological characters used in the 2004 paper with addition of character states observed from the holotype of C. umpqua, a minor reinterpretation of Character 14, and a correction of species name for the Sulphur Creek, Castle Crags State Park specimens (C. umpqua of Nelson 2004) as C. shasta. We ran a branch and bound analysis using this corrected matrix (Table 1). This analysis yielded six equally parsimonious trees. In all of these trees, the topology conformed largely to that of the tree in Nelson (2004) except that now C. nana falls into a polytomy with C. shasta and the two subgroups (Fig. 10). Still C. shasta is basal to C. jewetti. In three of these trees C. shasta is immediately basal to C. jewetti and in the remaining three it is also basal to C. regilla. Thus in the consensus of the six trees it appears as a polytomy with the two major clades in the Californica Group (Fig. 10) and C. nana. The more important question then becomes, “Where does true C. umpqua fit on the tree?” In five of the six most parsimonious trees, C. umpqua fits in a pectinate fashion up the tree from C. jewetti and down from C. ophiona. In the sixth tree C. umpqua is still up tree from C. jewetti but in a polytomy with C. ophiona and (C. californica + C. quadrituberosa). Zoogeography. With the consensus cladogram of purported relationships (Fig. 10) and the overall distribution of the group’s species in hand (Nelson 2004) one is tempted to hypothesize the origins, dispersal, and speciation sequence for members of the group. The zoogeography for the group as previously presented (Nelson 2004) stands. The Californica Group, taken as a whole (Nelson 2004, Fig. 3) divides into two sister taxa basally (Ventura Subgroup) and (Californica Subgroup + C. umpqua + C. jewetti). But our new species comes out in a polytomy with these two subgroups (and C. nana) and thus leads to no strong zoogeographic hypotheses. Capnia shasta is currently known from a single locality on a single date. It is currently known only from far down the flanks of Mount Shasta in a small tributary of the Sacramento River at the northern head of California’s Central Valley. We suggest that further careful winter collections of many sites in the area are warranted. We examined a range of specimens of C. umpqua from throughout its broad Oregon – southern California range. The shape of the epiproct in these specimens varied widely in relative width both within series from a single collection and across its range. Using this information we tentatively propose that C. shasta, C. jewetti, and C. ophiona arose as independent peripheral isolates from the widespread C. umpqua -like ancestor. This speculative hypothesis could best be tested using fast evolving sequences of DNA. We have little hope that further morphological study of this question will resolve these polytomies, and hope that the sequences will. Conclusions. This new, interesting species shows that small, relictual populations and species probably remain to be discovered in western North America. Careful, fine scale collecting of the numerous streams in northern California continues to yield new species. The limited distribution of C. shasta points to a need for careful conservation of the tributaries of the Sacramento River. The Californica Group remains an important and virtually untapped resource to learn more about the paleogeography of this part of western North America. The use of sequence data on a phylogeographic scale remains a next best step in sorting out the range relationships of these populations and species in understanding this perplexingly complex group of stoneflies.Published as part of Nelson, C.

Triznaka wallowa Kondratieff & Baumann 2012, sp. n.
Triznaka wallowa sp. n. (Figs. 1-12) Material examined. Holotype ♂, USA, Oregon, Union County, Fry Meadow Creek, Forest Road 62, above confluence Grand Ronde River, near junction of Wallowa River, 2 July 2011, C. Kerst (USNM). Paratypes (BYUC, CSUC): Same locality as holotype: 2 July 2011, C. Kerst, 4♂, 3♀; 23 July 2011, N. M. Craft, 8♂, 6♀. Male. Macropterous. Length of forewing 9-11 mm. General color yellow, to light yellow-brown. Head and pronotum with black markings, median pronotal stripe expanded anteriorly and especially posteriorly, with rugosities unmarked (Fig. 1); abdomen with mid-dorsal black stripe, extending from segments 1-8. Hammer present on sternum 7 (Fig. 9). Epiproct widest at base (Fig. 7), rugose at tip, bearing basally expanded scale-like spines anteapical to tip and on lateral edges, also bearing medial and basal setae (Figs. 7, 8). Aedeagus, ventrally with a distinct median band of thick reddish-brown setae arranged in longitudinal rows (Figs. 3, 4, 5, 6, 11, 12), aedeagal apex with a pair of triangular lobes, surrounded by patches of setae (Figs. 3, 4). Female. Length of forewing 10-11 mm. Coloration and markings similar to male, black pronotal stripe often wider. Subgenital plate often narrow at apex, lateral margins relatively straight to slightly convex, apical margin shallowly emarginate (Fig. 2) to relatively deeply emarginate (Fig. 10). Larva. Unknown. Etymology. The species name is a noun in apposition based on the Wallowa Mountains of northeastern Oregon. Diagnosis. The males of T. wallowa can be readily separated from the other three described Triznaka species by the distinctive ventral longitudinal band of reddish-brown setae on the aedeagus (Figs. 3, 4, 5, 6, 11, 12). The aedeagus of T. signata has a ventral broad mushroom shaped patch of golden setae (Baumann and Kondratieff 2008, figs. 15-17, 23, 24, 31). The aedeagus of T. pintada bears numerous large basal spines and an inverse V-shaped medial patch of golden setae (Baumann and Kondratieff 2008, figs. 12-14, 29). The basal half of the aedeagus of T. sheldoni in ventral aspect is covered with hair-like setae and a medial elongate patch of spines (Baumann and Kondratieff 2008, figs. 18-20, 33). The epiproct tips of the four species are similar, with flattened setae basally, and overlapping scales of spine-like setae apically as shown for T. wallowa (Figs. 7, 8). The subgenital plate of T. wallowa is narrower at the apex (Figs. 2, 10) than either T. sheldoni (Baumann and Kondratieff 2008, figs. 42-44) or T. pintada (Baumann and Kondratieff 2008, figs. 37-39), which can also have emarginated apical margins. REMARKS. Fry Meadow Creek was flowing on July 2 and 23 (Fig. 13) when both adult collections were made, but when Cary Kerst returned to the site on 15 August, the stream was dry (Fig. 14). The Wallowa Mountains are located in the Columbia Plateau of northeastern Oregon, an area often known as the “Alps” of Oregon. Most precipitation in the Wallowa Mountains occurs in the form of snow during the colder months and in the higher elevations, and usually from late July to mid-December there is little additional precipitation (Hamlet et al. 2005). Drying of streams such as Fry Meadow Creek may also result from decreased snowpack and earlier runoff that this region has recently experienced (Luce and Holden 2009). The Wallowa Mountains are relatively isolated from the Rocky Mountains to the east and the Cascade Range to the west. However, the stonefly fauna of these mountains is most closely related to the Rocky Mountains (Baumann et al. 1977). The Quaternary climate fluctuations and topographical variation of the region, including the Wallowa Mountains, may have isolated a clade that gave rise to T. wallowa as has been reported for other faunal elements (Chavez and Kenagy 2010). Additional adult stoneflies collected by Nadine Craft with T. wallowa included Podmosta decepta (Frison) and Suwallia sp.Published as part of Kondratieff, Boris C. & Baumann, Richard W., 2012, A New Species Of The Western North American Genus Triznaka From Oregon (Plecoptera: Chloroperlidae), pp. 10-15 in Illiesia 8 (2) on pages 10-15, DOI: 10.5281/zenodo.476065

Vesicle narrow and elongate, broadest medially and near apex, with thin base, vesicle surface covered with many rounded pit-like indentations, basal and lateral margins bearing thin hairs (Figs. 7, 12). Cerci with mesobasal lobe, nipplelike and unsclerotized, with rounded tip directed inwardly towards the cerci, lobes and cerci covered with many stout hairs (Figs. 1, 6). Female. Macropterous. Body length 7.0-8.0 mm, forewing length 7.0-8.0 mm. Color and general morphology similar to male. Seventh sternum produced medially into small stout nipple-like structure, medial portion of sternum swollen. Eighth sternum with median V-shaped notch, notch deep and extending to base of segment, lateral margins of segment bordering notch swollen (Figs. 5, 13). Swollen portions of sterna 7 and 8 are more visible in lateral aspect. Larva. General morphology typical for the genus (Baumann 1975, Stewart and Stark 2002): male body length 5.5-6.5 mm, female body length 7.0-8.0 mm. General color brown. Cervical gills present, two pairs located on each side of midline, gills found both inside and outside of lateral cervical sclerite, each set composed of 6-8 gills, usually with the actual number being 7 in undamaged specimens. Etymology. We are pleased to name this species after our friend and colleague, the late Chad M. Murvosh, who collected the first specimens that are part of this study. Chad was a well known aquatic entomologist, with expertise in the water penny beetles or Psephenidae. He collected many interesting aquatic insects throughout western North America during his career at the University of Nevada at Las Vegas. Diagnosis. Malenka murvoshi males can be separated most easily from its closest congeners, M. biloba (Claassen) and M. coloradensis (Banks) by the shape of the paraprocts. In M. biloba, the median lobe of the paraproct has a bilobed apex, the larger outer lobe is longer and cultriform, while the inner lobe is stout with a triangular apex. The median lobe in M. coloradensis has a nearly truncate apex, terminating in two short stout tips. Whereas, in M. murvoshi the apex of the median lobe is scythe-shaped with a large sharply pointed apex, but bears a short stout spine on its outer margin (Figs. 4, 11). All three of these species share the character of simple mesobasal cercal lobes which are nipple-like and not apically acute or darkly sclerotized (Figs.1, 6). Females cannot be separated without associated males by external characters. Nymphs may potentially be separable by the number of gill branches on each side of the cervical sclerite from sympatric species, but this character requires further study. Remarks. The Spring Mountains of southern Nevada range northwest-southeast between Las Vegas and the California border and are isolated from the many north-south oriented ranges in the Great Basin portion of Nevada. The highest point is Mount Charleston, at 3,633m. Extensive collecting of the region indicates that M. murvoshi is apparently endemic to these mountains. Malenka coloradensis, however, was collected in Deer Creek only a short distance south of the known localities for M. murvoshi. It is interesting to note that the three Malenka species that were discussed in the diagnosis have the most southern distribution of the genus in their respective states in the United States and Mexico: M. biloba California and Baja California; M. coloradensis: Arizona, Colorado, Nevada, New Mexico, South Dakota, Utah and Wyoming (Stark et al. 2009); M. murvoshi only in southern Nevada.Published as part of Baumann, Richard W. & Kondratieff, Boris C., 2010, Malenka Murvoshi, A New Species Of Stonefly From The Spring Mountains Of Southern Nevada (Plecoptera: Nemouridae), pp. 113-117 in Illiesia 6 (11) on pages 114-117, DOI: 10.5281/zenodo.475976
